QCY — bluetooth headphones
I have bought their headphones on Aliexpress. It took a long time to receive them. The operation of the headphones is complex and uncomfortable, the sound is (very) poor and they are so heavy that they keep falling from my ears. I have tried to send them back (on my account) and get a refund (brand new unused in the original box and they keep dragging me with a zillion requests (I have sent a video and a detailed description) and they keep asking for more. They do not answer to emails and they wear me down until I will quite. It is a waste of $35. Try to avoid buying from them.
