Paying this much for a headset seemed a bit much. but after charging it and setting it up for my xperia Arc. this headset is brilliant. rang my friend to test if it was crystal clear sound. i hear my friend very well. as could he on his end. i put mp3's on its 2gb memory card for when im out and about. plus if u play mp3's off the headset, you will drain the phone a lot less. volume is quiet loud, thou Ive sensitive hearing, so it does the job for me. when u get texts, it comes on its little screen, if its set for voice, it will say the message to u at the press of a button. really love that feature. you can download a few different voices for the headset, be it English or American voice overs. as well as other languages. other apps can be installed also when they released. all in all, this headset is a great buy. i would recommend to anyone.
