- Autonomy
- Apps on the smartphone
- Changes firmware updates
- Bluetooth and FM reception quality
- I personally do not use integrated micro-SD card but I think it's a very good idea because it makes an independent MP3 player.
- Quality of headphones (with MP3 files of good quality)
- Finish the helmet and the product in general
- Perfect to make or receive calls
Bad points:
- On my Galaxy Nexus (alternative ROM), I have to manually start the Music application. When I click Play, it will not launch automatically. I think it is related to the alternative ROM because I put on an official ROM on the Galaxy S3 to my partner, everything works perfectly. I think the Xperia range, everything should also work without problems.
- Quality of headphones (with MP3 files of poor quality, below a certain bitrate)
- Packaging quite difficult to open without breaking
Brief summary, I highly recommend this headset. I have tried many and this is really the first that gives me satisfaction as integration with the smartphone is pushed and the product finish is excellent. It is a true Swiss knife with all features (Bluetooth, FM, MP3 independent, Apps, ...).
