They are pretty good. They get really loud, sound is good ??

There is a loud hissing when they are on

On sale<$20. Grezt low latency and battery life. Equivalent LaLatecy headphones are $55-75. Decent sound and battery gas never run low even after 5 hours use.

The sound is good for now. The Bluetooth is not sometimes connected to my MP3 device..

Bought it on monoprice ebay, Apx X low latency works great and range is very long with my avantree DG60 transmitter, sound quality is good for the price, bass is boosted, not the most accurate but good enough, and its got clear highs.
Build quality is good with metal hinges, impressive for the price.
Its that middle sized ear cup which is partially on your ear so depending on the size of your head you will few pressure after a while, so not all day wear of large sized ear cups.
Easy to pair and the slide on switch is a nice change from the press and hold.
The listing is wrong on Bluetooth 4.2, it is 5.0, both on box and manual.
The charge port is micro usb though, matters much less as I use magnetic charge adapter cable to make charging easy.

These headphones are absolutely amazing for the price. They are very sturdy and well built for earphones of this price. They do not have the wall shaking bass, but rather a well rounded and tight base that goes well with the mids and highs. Bluetooth works well and there are no lip sync problems with video. The only negative that I could find is the ear cups are just a little small for over the ear headphones.

Its a decent headphone for the money. These replace my original monprice which were discontinued.
I would spend more for better sound i dont know whats better bc you have anc factoring in the price of some cans.
