Removed 1 star because of the ridiculous blinking blue light -- if you plan to use these headphones in a darkened room, you just may be driven mad by the constant blink blink blink

If used in a dark room, it is best to use the headphones with the auxiliary cord

This is minor, but obnoxious when using in a dark room, eg a movie.

Also the blue power light could be smaller, annoying in a darkened room.

And the most important part, no noticeable sound leakage even on full volume!Only thing I dislike is the flashing blue light when it's paired which is very noticable/distracting at nights in a dark room, but I can live with that or just use the cable.

I often wake up in the middle of the night and want to listen to music or an audiobook until I get sleepy again but that bright flashing light illuminates the whole room, wakes up my husband and gives him seizures!

It's definitely bright and easily noticed when using in a dark room

, headphone wire works great if you don't want to use bluetoothCONS:- size is a bit bigger than I expected, blue light is waaay too bright and blinks every few seconds or so if you're on bluetooth - not an issue usually, but in a dark room or airplane it's really annoying

The light of the on/off button may only be disturbing if you tend to use it in a dark room.

The light that blinks when they're turned on and connected is really bright and kind of annoying, especially in a dark room or bus, but that's nothing a small strip of electrical tape can't fix if you're not OCD with putting stuff on your electronics

They are great except for the completely annoying bright flashing LED light that lights up a dark room while you're using them.

This light is VERY annoying when in a dark room and the main reason I have this product 4 stars rather than 5

It can be distracting at times, especially when you are in a dark room
