Doesn't even deserve 1 star Doesn't even deserve 1 star. Headphones arrived DOA. Filled out website submission form, emailed multiple times, called (no answer). I finally gave up and disputed the charge through my credit card company. They've refunded my card, apparently they couldn't get hold of them either.

This company is a total scam This company is a total scam! While I did actually receive my headphones, the microphone was not working and I immediately tried contacting the company for a refund or exchange. Emails went unanswered, no online chat or phone available to try and get in touch with a real person. I even paid to have these shipped back and included the refund request form with my emails backing up that I did try to reach out to request refund within 30 days and still no response. No refund, not even exchange. NOTHING! I learned the hard way this company is a total scam.

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?

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

Great product but absolutely awful Customer Service Great product but absolutely awful customer experience. I bought a pair of headphones that arrived and worked as expected. However, they don't fit me right and were uncomfortable so I wanted to return. Good luck. I've tried emails, the refund form, phone calls, and anything else I can think of to no avail. Seems like this company only creates products while everything else is sham. I'm completely done with Cowin.
