Didnt charge my phone really and battery doesnt last super long. I wouldnt recommend Keen, thier priced like a quality product but built cheaply and dont stand buy thier product. ubon sp 6770 As I ordered these via Amazon, my return option had expired, which was very disappointing. As for sound, there is plenty of bass, but its natural sounding, tight and punchy, and doesnt overwhelm the other frequencies of the audio spectrum. ubon sp 6770 I purchased the headphone plus the charger set and then ordered a single Sennheiser headphone so both my husband and I can listen to movies or just the television at different levels of hearing. ubon sp 6770 I have run the device and it all looks to be working perfectly well; the thumb print is good and the operation is smooth and quick. mine washed well in cold water and low dry. Picture attached. ubon sp 6770 More out of habit than necessity. the instructions are a bit off, but you are smart and will figure it out.
