Fake electronics fiascos

Until recently, at least to the best of my awareness and recollection, I’ve only been fooled into three purchases of counterfeit tech devices, all of which I’ve documented in past blog posts:

1. Hands-on review: Is a premium digital audio player worth the price? (Specifically note the mention within it of my acquisition of two fake-capacity 400GB microSD cards)
2. Memory cards: Specifications and (more) deceptions, and
3. USB activation dongles: Counterfeit woes

In the first and third cases, I should, in retrospect, have known better, since the devices I bought were substantially lower priced than equivalents from more “legitimate” seller sources. The second case was the seeming result of someone returning to Amazon a falsely labeled subpar substitute for something they’d bought, and Amazon not catching the switcheroo and reselling it as legit on the “Warehouse” area of their site. In all three cases, happily, I got my money back.

Mercari’s previous track record

This fourth time, unfortunately, I wasn’t so lucky. And the deception was, if anything. more impressive (among other, less-positive adjectives) than before. Mercari, for those of you not already familiar with it, is a Japan-based buyer/seller intermediary online service in the same vein as eBay or (for audio gear) Reverb. It’s generally considered to be more “seller-friendly” than eBay; how much so will become clear shortly. My first (recent) purchase there, which went smoothly and successfully, was of a headphone amplifier. I subsequently picked up a matching equalizer from the same manufacturer (Schiit Audio) via another seller, along with two Raspberry Pi AI Cameras and a special-edition Ray-Ban Meta AI Glasses set, the latter which will be showcased in another writeup (a pseudo-teardown, to be precise) this month. All went fine.

The sixth Macari-coordinated transaction? Not so fine. Perhaps, in retrospect, the prior track record lulled me into a false sense of complacency. More likely, I just “wanted to believe” too much, referencing the memorable X-Files poster- and character-delivered quote:

I’d been watching the for-sale postings of a seller with username “Skii” (apparently short for “skiitheflipper”) for a while. This person regularly listed claimed-legitimate and factory-sealed 2nd-generation Apple AirPods for sale, and Mercari dutifully let me know each time “Skii” lowered his sales price on the particular set I was watching. When they hit $93, I was seriously tempted. And when Mercari did a one-day free-shipping promotion, I bit. The total price, including sales tax and a $3.54 “buyer protection fee” (cue foreshadow snort), was $100.88.

A pause here for some background: first off, given that I already had both a primary and backup set of first-generation AirPods Pros, why was I interested in a second-generation set the first place, particularly with the AirPods Pro 3 rumored to arrive later this year? At the normal $249 price, I wasn’t. Even at the fairly common $189-or-thereabouts promotion price, I didn’t pull the trigger. But why the interest at all? The AirPods Pro 2, in comparison to the first-generation forebears I already owned, have claimed superior active noise cancellation, for example, along with dynamically adaptive “transparency” mode and longer battery life. More recent gen-2-only enhancements include the Hearing Aid feature, which I don’t require (at least I don’t think so! What did you say?) but still wanted to try. And the further temptation of possibly upcoming Live Language Translation pushed me over the edge…once the price tag dipped below $100, that is.

About that price…many of you are likely right now thinking something along the lines of “Were you really so stupid as to think that something sold at a roughly 2/3 discount to MSRP was legit?”. Actually, I wasn’t. Although, hey, who knows…per the “flipper” portion of the seller’s username, maybe he or she had scooped up the inventory of a going-out-of-business retailer and was reselling it. Regardless, I figured that I’d give the purchase a shot, and if it was a fake (as I assumed would be immediately obvious) I’d file a dispute and get my money back. Which was conceptually feasible, mind you. But as a Mercari newbie, I didn’t realize how difficult it would be, both in an absolute sense and in relative comparison to eBay (on which I’d been a regular participant since 1997), to translate the buyer-refund concept into reality. Hold that thought.

The listing 

Back to my story. To his credit, the seller at least was speedy from a delivery standpoint; the package shipped on Tuesday, April 1 (April Fool’s Day: how prophetic) and arrived that same Saturday. At first glance, at least to my uneducated-recipient’s eyes, everything looked authentic, although had I known more/better I never would have clicked on “buy” in the first place. Here are the photos that accompanied the listing:

Looks legit, right? Only one problem, I later learned: Apple reportedly no longer sells AirPods in shrink-wrapped boxes. But pretend for now that, like me at the time, you’re not aware of that critical nuance.

The delivery

Here’s the (shrink-wrap already removed) box of the actual product I received, as usual, accompanied by a 0.75″ (19.1 mm) diameter U.S. penny for size comparison purposes:

The tape strips at the top and the bottom were seemingly “stiffer” than I’d remembered before with other Apple devices, but I didn’t give that much thought, eager to get inside:

Getting the two halves of the box apart was similarly more difficult than I’d remembered …but again, I now have the benefit of hindsight in making these key-nitpick observations. The literature package up-top seemed to be legit:

The protective plastic sleeve around the case admittedly also seemed flimsier than I’d remembered from other Apple earbuds (there’s that rear-view-mirror perspective again):

Putting the case aside for a minute, let’s look at the rest of the contents (again, a reminder that these shots were taken post-initial removal). Extra earbud tip sizes:

And below them, an authentic-looking and functional (at least for charging) USB-C cable:

Now for that case. The LED in front seemingly operates as expected (both green and orange illumination mode options), as do the speakers and USB-C port on the bottom edge:

Open the case: it still looks, sounds (beep!), and otherwise acts legit.

Earbuds out: Charging contacts at the bottom of each receptacle.

The earbuds themselves, from various perspectives. Apologies for the earwax remnants

“That’s odd.” 

Back in the case for initial pairing, which is where my initial “that’s odd” moment happened (hold that thought for a possible explanation to follow shortly):

I didn’t recall this particular message before, particularly for supposedly brand-new Apple earbuds, but I plunged on and got them paired and associated with my Apple user account straightaway. They automatically also appeared in the paired-Bluetooth-devices listings of all my other Apple widgets. One thing that seemed a little strange upfront was that “Handoff” mode, wherein I could connect to them from another account-associated device even if they were connected to a different device at the time, didn’t seem to work. I instead needed to manually disconnect them from, for example, my iPad before I could connect them to my MacBook Pro. But after a bit of online research, I chalked that up to a potential bug with the earbuds’ current firmware version (7A305, which dated from late September 2024). And about that…check out the three-part post-activation settings listing:

All looks legit, right? The earbuds even claimed that valid warranty coverage existed through June 2025! Activating noise cancellation seemed to do something, although I can’t say it was notably superior (or even equivalent) to what I’d experienced with their first-generation forebears. And when I tried to activate hearing aid mode, it told me that I’d have to update the firmware before that particular feature was available for my use. All reasonable. When I tried “Find My” on them, it couldn’t locate them, but I figured that since I’d just activated them, Apple’s servers were just slow and they’d show up eventually. So, I connected them to my iPad, put them in close proximity to it so that the firmware would auto-update, and…

Mercari’s seller rating policy

Another background-info pause. As soon as USPS delivered the earbuds, Mercari as-usual sent email alerting me that they were at my front door and—this is key—immediately encouraging me to “rate the seller” so he or she could get paid. From past experience, those emails would continue at a one-to-multiple times-per-day cadence until I either reported a problem or went ahead and rated the seller. And here’s the twist that I didn’t realize until afterwards:

• The buyer has only 72 hours after package delivery to report a problem
• In the absence buyer response to the contrary after (only) 72 hours, Mercari goes ahead and automatically marks the package as received and pays the seller anyway (remember my earlier “seller-friendly” comment about the service?), and
• Once the transaction is complete, Mercari washes its hands (words ironically written by me within the Triduum) of the matter and accepts no further fiscal responsibility.

Did I go ahead and rate the seller that same evening so that he/she could get promptly paid? Bathed in the “giddiness glow” of a seeming legit transaction…yes, I did. Sigh. The next morning, of course, when I checked the settings and saw that the firmware had not updated, alarm bells belatedly started going off in my head. Multiple subsequent factory-reset and re-pairs were equally unsuccessful in getting the firmware updated. And then I found this video:

Different serial numbers on each earbud

wherein I remembered that although the serial number on the packaging matched that on the case and (by default) reported in settings, the serial numbers for the right and left earbuds were supposed to be different in both places. Here, for example, are the serial number markings on the case and earbuds for my first-generation AirPods Pros (apologies again for the earwax bits):

The print is a bit faint, but hopefully you can see that the serial numbers on the earbuds both don’t match those on the case (H6VHW8651059) and are different from each other (H6QHWQRX06CJ and H6VHX88Q0C6K).

Now here’s the settings listing entry of interest for the “fakes”. If you click on it, it’ll report unique serial numbers for the case and each earbud:

And the model numbers stamped on the case and both earbuds are also different, and match what they should be. But the stamped serial numbers on all three? Identical: DT601W1T41.

And are, I’m guessing, also identical to the serial numbers stamped on and reported by who-knows-how-many other identical “fakes” also sold by “Skii” and others, which is why I got the initial “not your” notification at the beginning of the pairing process. Apple, is it not possible to detect and more meaningfully alert owners when multiple sets of earbuds with identical serial numbers are activated? You have both fiscal and reputational motivations to do so, after all.

I’m begrudgingly impressed with the degree to which these counterfeit earbuds mimic the real thing. And here’s the twist: were I the owner of only a single Apple device, such as an iPhone, therefore unaware of the “Handoff” glitch, and were I a typical non-geeky (non-Brian) consumer, unaware how to determine the existing firmware version, far from what the current version is, how to update it and what it would add to my usage experience…I might be blissfully unaware far into the future that I’d bought a cheap-but-fake set of earbuds …maybe forever.

Reporting the fake to Mercari

I reported the situation in detail, complete with pictures, to Mercari. Throughout the subsequent email back-and-forth, they several times reminded me that:

When you submit a rating for your transaction, you are prompted to confirm you understand that once the rating is submitted, the sale is final. Once submitted, funds are released to the seller and we are no longer able to process a return or refund. Moving forward, if you receive an item that is not as described, please do not submit a rating for your seller and contact us immediately.

That said, they also made a promise:

Please know that if a report is made against the seller we will conduct an investigation to confirm the suspicions. If the seller is found guilty immediate action will be taken against them regarding their listings. I appreciate for your concerns and just for you we will further review this for you. Your case will be taken as a feedback and we do value your time in reaching out to us to inform us of this inquiry.

and:

Regarding your seller’s action, please note that our team is very vigilant with those kinds of activities. We will conduct monitoring where we will need to check all their transactions and make sure that our Trust and Safety team will review this concern. Please leave it to us, rest assured that the right sanction will be given accordingly.

It’s been two weeks since I filed my report. “Skii” is still on Mercari. And as I write these words, he or she has three more “authentic” AirPods Pro 2 sets for sale. Admittedly, “Skii” may not even know that the earbuds being sold are fakes. Although I doubt it. Caveat emptor, indeed.

Then there was this closing email from Mercari:

Thank you for reaching out to Mercari! We hope your issue was resolved to your satisfaction.

We would appreciate it if you could take a moment to provide us with your feedback. Your input helps us improve our service. Thank you for helping us serve you better!

Grrr.

I plan to “turn lemons into lemonade” via future teardowns of both the case and one of the earbuds, comparing them to existing published teardowns of legit alternatives. Until then, I welcome your thoughts in the comments on what I’ve written so far on this “fakes” saga.

Зустріч між новим головою Наглядової Ради і керівництвом КПІ ім. Ігоря Сікорського kpi пн, 06/09/2025 - 19:09

Editor’s Note: This DI is a two-part series.

In Part 1, Nick Cornford deliberately oscillates the TDA7052A audio power amplifier to produce a siren-like sound and, given the device’s distortion characteristics, a functional Wien bridge oscillator.

In Part 2, Cornford minimizes this distortion and adds amplitude control to the circuit.

In the first part of this Design Idea (DI), we saw how to use the TDA7052A (or similar) power amp to build a minimalist siren-type power oscillator, and also, having looked at that device’s distortion characteristics under various operating conditions, a simple but half-decent Wien bridge oscillator. In this second part, we’ll turn that semi-decency into something even more respectable, concentrating on minimizing distortion and ignoring the siren song of raw power. We will also stick with a 5-V supply, even though the chip can handle up to 18 V. Figure 1 shows the new circuit.

Figure 1 Adding more precise level-sensing allows much better amplitude control and also reduces distortion.

Most of the changes are in the control loop, but input resistor R5 has been increased because we have more gain available now that Vcon can be driven high as well as just being pulled low. In passing, the series combination of R5 and U1’s nominally 20k input resistance shunts R2/R4 a little; a slightly disturbing operation. Adding 120k across R1/R3 could compensate for that, but the practical difference is tiny. The gangs on twin pots never quite match anyway, so using the lower-value half for R1 is good enough.

Wow the engineering world with your unique design: Design Ideas Submission Guide

The control loop, detailed

Peak output levels are now sensed by comparison with the reference voltage defined by R9 (or its wiper) and R10. (Be careful: pot R9 and fixed resistor R10 should match, so the latter may need to be trimmed.) The junction of R11 and R12 floats at ~650 mV until the peak amplitude exceeds the reference, when D1 or D2 will briefly pull it lower by ~450 mV. The resulting attenuated pulse stream is filtered by R6/C6 and R7/C7 and level-shifted and buffered by Q1 into U1’s Vcon pin. That attenuation is necessary because the effective control-loop gain would otherwise be excessive. U2 is an MCP6022, which has a low input-offset voltage and is fast enough to work well as a comparator. The overall temperature stability is good, the output level scarcely changing between 20°C and ~50°C.

Any residual ripple in a control loop like this will cause distortion by modulating the signal. It’s minimized by the lead-lag filter R6/C6 and C7/R7, which also controls the settling time. The values used leave the loop somewhat under-damped at low frequencies, but are a good compromise.

The spectra with unloaded outputs at 0 dBV and -10 dBV are both shown in Figure 2.

Figure 2 The spectra for 1 kHz outputs at 0 dBV and -10 dBV, showing THDs of around -60 and -73 dB respectively—say 0.1% and 0.02%.

Further reducing the output levels doesn’t improve distortion much, partly because this control scheme then becomes less stable. Any offset of one output relative to the other can result in one “phase” of pulses being missed, leading to increased second-harmonic distortion, as implied by the relative levels of second and third harmonics for the two levels shown in Figure 2. Trimming the power amp’s offset makes surprisingly little difference, so it isn’t implemented.

Trying to derive the control voltage from a more complex full-wave rectifier gave virtually the same distortion figures, so we’ll stick to Figure 1’s circuit, run it at -10 dBV or a little less, and accept its THD.

 Some finishing touches

Swapping the capacitors C1 and C2 for 3n3 and 330n parts gave the expected performance on higher and lower ranges, though distortion was a few dB higher on the low range, and the level was less well-controlled at the highest frequencies. All that’s needed to turn this into a useful kit is an output stage, for which the fairly conventional circuit of Figure 3 works well.

Figure 3 A simple output stage can deliver up to about +5 dBV, which is the rail-to-rail swing for a 5 V supply.

The extra stage adds almost no distortion, and leaves a spare op-amp (U3b) which could be used to invert the signal from U3a to provide antiphase outputs. One final spectrum, taken with the oscillator set for -10 dBV and the output for a swing of nearly 5 V, is in Figure 4. That confirms an overall THD of -73 dB, or 0.022%. Hardly earth-shattering, but still quite decent.

Figure 4 The spectrum at the output of Figure 3 for an output of ~+5 dBV.

No tweeters were harmed in the making of this DI, though a 10-Ω, 1/4-W load resistor started to smoke. A 1-W part would have been healthier, as it would only have vaped.

—Nick Cornford built his first crystal set at 10, and since then has designed professional audio equipment, many datacomm products, and technical security kit. He has at last retired. Mostly. Sort of.

Anritsu Company will exhibit cutting-edge high-speed signal integrity solutions at the PCI-SIG Developers Conference from June 11-12 in Santa Clara, CA. Anritsu will present PCI-Express  6.0 and 7.0 live demonstrations of the industry-leading MP1900A BERT in collaboration with Synopsys, Teledyne LeCroy, CIG, and Tektronix.

Live Demonstrations

World’s First PCI-Express 6.0 Link Training over Optics

Anritsu is joining forces with Synopsys, Tektronix, and CIG to demonstrate the world’s first PCIe 6.0 optical connection link training using the Anritsu MP1900A BERT, Synopsys PCIe 6.x PHY and Controller IP, Tektronix DPO70000 Real Time Oscilloscope, and CIG OSFP LPO optical module.

PCIe over optical links provides higher bandwidth, covers longer distances, and is more energy-efficient, effectively addressing key bottlenecks for AI workloads in data centers.

This joint demonstration highlights Anritsu’s leadership in next-generation optical PCIe.

PCI-Express 7.0 Differential Skew Evaluation

In collaboration with Teledyne LeCroy, Anritsu will present a solution for evaluating the effect of differential skew in PCIe 7.0.

PCIe 7.0 uses PAM4 signaling, which reduces eye height by more than three times compared to NRZ. Combined with the speed increase from 32.0 Gbaud in PCIe 6.0 to 64.0 Gbaud, this results in a smaller unit interval (UI) that is significantly more sensitive to skew.

In high-speed environments, signals traversing an ISI channel may exhibit a dip in the fundamental frequency due to skew. While most BERTs lack built-in skew evaluation functions, Anritsu addresses this by using two MP1900A MU196020A PAM4 PPG units with the Channel Sync function to inject P-N skew and Teledyne LeCroy’s WaveMaster 8650HD 65 GHz oscilloscope for advanced analysis.
