I don't know why these bad ratings, it's weird. I bought them, they have a good sound, depends what you send out of your mobile phone/music player. I use an equalizer, there is bass, treble, everything. Of course they are gonna be bit bulky, how else fit in a battery that will give you over TEN HOURS of playback on normal volume ? I use maxx volume and loudness, and I get easy 8 hours ! Show me earpieces that can do that under 100 euros, and I will show you a flying pig. Very satisfied, recommended to a friend, he tried it, he said they are good. Best buy !
