Good to use with some extra apps

Optical Sony MBH10 has me already really liked on the product picture, unpack the feel convinced. An on / off slide would be practical, it is sometimes not clear whether the device is actually made of.
As had noticed some reviewers, the maximum volume is not very loud, I had doubts whether I can understand my interlocutor at higher speeds well, practice test but then found that the volume is sufficient, although it would be more comfortable yet a little louder be able to switch.
After about 20 minutes I find the earloop uncomfortable, I wear the headset in the meantime without the earhook. Now it is very pleasant and it keeps sufficient strength without the strap in the ear.

The biggest complaint is the inconvenience for me; I (with Nexus 5) use the headset to make calls mainly in auto answer (not even to make calls). I have now forgotten to turn on Bluetooth on my Nexus and "pairing" with the headset to I can not directly use the headset with an incoming call. Also NFC does not work when it "is ringing". So I need to either always remember to join before the call or call back the caller to connect. However, I have found a couple of apps that solve this problem for me and MBH10 Curling handling the Sony lot more pleasant, here the links:

Bluetooth On Call - ensures that as soon as I make a call or receive a call Bluetooth is activated. Then I have to turn on only the headset, the call on the mobile phone (on the headset works here not) annnehmen and can make phone calls with the headset. [...]

Bluetooth Auto Connect - is also needed; Thanks to this app will once Bluetooth is activated also connected to the headset. [...]
Mono Bluetooth router - Unfortunately, I could no music, navigation instructions etc. hear with my Nexus 5 in the headset, but only calls. Thanks to this app that works now. [... 9
Conclusion: With these apps, I'm quite happy with the headset. Without I could not keep it well. I find it a bit sad that the volume level is so low and that, for example, no calls can be made via voice control. Unfortunately, this is subject to the höherpreisigeren headsets.
