I've owned these for a few weeks now and after only 15 mins the outside edges of my ears began to hurt. The fit is too tight and the little pads are too small for normal ears. Sound quality is good and instructions are very simple. I appreciate the long battery life but I can't even wear the headphones for a longer period of time than 30mins.
I bought these on a semi-whim as I was looking for affordable Bluetooth headphones that I could wear on a flight. I despise earbuds and these are super comfortable! They are a bit tight as other reviews have indicated, but it is not something I find bothersome. The sound is GREAT! I listen to music and podcasts all day at work and at home, and while I'm not the biggest sound snob, I've been known to retire headphones after a few listens if the sound is a little bit bad. These are great, especially for Bluetooth!
Just got these. Worked great right out of the box. Awesome frequency response. Swept sine wave from 18 Hz to 18kHz. Very flat spectral response and powerful bass. love them!!
