Review on KZ ZSN Headset Hybrid Technology 1BA 1DD HiFi Bass Earbuds In Ear Monitor Sport Noise Cancelling Headphones (With Mic by Dawn Kraft

Bass and treble are "fun" like most IEMs and headphones, which may be too much for some, so consider adding an EQ to them to tone them down a bit. Another thing to note is that Revain's product description mentions ANC; They definitely don't have that, but they do have pretty decent passive noise isolation. However, they sound a lot better than some of the $150 IEMs I've had in the past. I kick myself for sleeping in the Chinese hi-fi scene for so long. I would only deduct a star for my own arrogance but they are more than good enough to make up for it.
