Cowin Audio is a scam! Do not buy! They don't respond to costumer support emails!! I purchased Cowin E7 headphones in August of 2022. As per Cowin's warranty policy if you purchase from their website your purchase is secured under a two year warranty. About a year after my purchase (July 2023), the audio went out in my headphones. I have been attempting to contact their email help line for nearly a year at this point. I have never received a response despite sending four emails. Their email is the only contact line listed on the COWIN website.

Low Quality for a high price tag Noise cancelling had a high pitch with low volume clicking every second. Reached out to customer service. They never replied to my emails. They never answer the phone. I lost 49 dollars on this purchase. Save the hassle and never buy from Cowin or anything advertised as E7

All measurements are way way off A nice looking watch, but don't rely on anything other than the time and date. The Bp, Bs, workouts, sleep measurements etc. are just way off, maybe as much as 30%. But because they have stolen all your personal information, its a victory for them. I've tried 2 support emails and their official site messaging and no answer regarding my request for return. The delivery date may be intentionally delayed so that it's impossible to protest your charge card when you've already paid. This is fraud even China might not approve of....

Similar to many others here Similar to many others here - I ordered a replacement pair of E7s after using mine daily and loving them...but no delivery two months later, no response to any customer service emails...nothing.

Not fulfilling the order I see many similar posts here — ordered their headphones on January 6, and nothing since then, the tracking app says order received and that’s it… emails are unanswered… It’s a shame because I used to have E7 and they are very comfortable and noise canceling is great, they died after couple of years of heavy usage which is fine. But what’s going on now with them looks like a total scam, taking money and not sending anything. What happened?
