Good sounding earphones are usually a bit of a gamble as there are very few places that will let you try them (due to OH&S). So I read a number of reviews and rolled the dice on these. The sound gives me that bottom end that helps round the sound beautifully for me. Comfortable however bulky but I prefer sound quality over aesthetics in this case. Charge lasts about 8 hours. Very happy. And not too expensive compared to some other out there.
