The XBA-BT75 can be quite like ....

Delivery
Ordered yesterday, today I hold the XBA-BT75 in my hands, Amazon is quickly and reliably as always .....

Bluetooth connection
Connecting to the iPhone 5 went fast and without problems. The connection is clean and without interruptions. Reach a wall and then come 6m interruptions.
What stands out very positively: tracks back and forth, raking start and stop without and interference. What else I already negative in many Bluetooths headsets noticed (eg MDR1BRT).

Creating, comfort
Equip the headset is the first time somewhat tricky but you get used to quickly. I have a soft rubber made around the cable which I closely sits create the high order sliding the cable head. So the HS sits really safe and annoying grinding noises attributable almost entirely.

If I would like to take my environment better I pull one of the plugs from the ears and but let him hang over the ear. Now I can talk to my wife and the current music is not so mutilated. At least I will always do that before when I put a plug in a normal inEar headset.

After an hour wearing and not bother pushing it.

Sound
The sound of the XBA-BT75 is clean and pleasant. The subtleties of music are well resolved. For my taste might be a little more bass. (... Perhaps Sony is indeed a jerk and still builds a second driver unit in the next model).
For those who like it loud .... the thing is, according to bear only seconds at 100% and the bass is a little unclean.

During a telephone conversation the interlocutors is very clearly heard and also my opponent hears me clean.

Processing and accessories
The XBA-BT75 a quality image and tidy processed. The charging station can I find impractical but not a direct charging port on the headset would not be bad.

Battery performance may be higher, 3.5 hours are not much but for my habits sufficient .....

Conclusion
The people who are not put off by the price, not calling all day listening to music and and need a hammer bass will be very pleased with this headset.
Oh appeal ..... Siri can not.
