My first Bluetooth headset from Nokia was - not bad but I wanted to stereo - so I took a Jabra BT on strings.
So I was happy but these in-ears bothered me so I bought something first favorable - a call Stel HZ.
That was tonally not what you would expect from HiFi, did not fit so well and went very quickly broken and I bought a Samsung SBH 170th
That's not a bad headset - Sonically super - I thought until now - had a hook - on my Nokia N8 went just making calls or listen to music, you get a call while listening to music - you can indeed ran go but the mic is not turned on or something does not go quite definitely hear anyone ... on both sides ... And that annoying after all.
Now I have the Halo2 straight times for 6 hours've listened 4 albums and am thrilled - superb sound a little bassy but these are my Sony MDR-V700 also and have no AV Surround !!!! Some complain about the lack of foreclosure but there are just open headphones and I think it's still bearable what comes through because you do not want to be run over by a truck because you Trant also. The volume is good - and on the train you have not even full blast listening to music that one bothers his neighbor. The service is awesome - Touch sensor and for the price !!! The grip is good - for people with a big head, he may quickly press since he is quite inflexible but I got him on since 4h and then pushes nothing.
The first impression of telephone sound quality was good enough - but was even indoors - outside and in windy conditions is still being tested.
My conclusion so far - just buy it
EDIT:
So after much carrying, Horch and Telefoniersession also out very well. I was well understood and have also heard all good.
