For the price, these headphones are quite comfortable and the sound is very good. Very happy with my purchase. One problem I have noticed is when I share a headphone with my mom when we go walking so we can listen to talk radio and keep an ear open, the sound will cut out for a second every 15 seconds or so. I don't think it's due to a low battery since I store my headphones in its case so I'm assuming the headphones are charging... right? Not sure if both headphones need to close to each other since it doesn't happen when I'm wearing both... although bluetooth range is further than we ever get. Very annoying, but still great headphones.Update: Somehow I got my headphones unsynced and can only use them one at a time and there are 2 bluetooth connections listed in my device list on my Android phone. So I referenced the manual and it does give instructions for "reorganizing the two headphones", but NOTHING described in the manual is what happens in real life. It mentions white and orange lights, but I have red and blue lights that flash. It tells me to take the headphones out of the case when "the orange light is on"... WHAT ORANGE LIGHT? I can't tell which light are on on the headphones when they're still in the case... or did they mean some orange light on the case? I don't know. The whole miscommunication could be due to a language barrier, but OH MEIN GOTT, Germany should have some native English speakers around to get this right (I'm totally guessing it's a Germany company since the instructions only come in English and German and I can tell the English is a translate)! Blue ist blau und white ist weiß. Es ist nicht schwer! Nevertheless, even with making educated guesses to what's meant in the manual, nothing worked... no-thing!Tiksounds, get at me and help get my headphones synced again if you want my faith in your product and my 5-star review restored.
