The bracket by clamp onto the visor fits on my Volvo C30 just (thickness 1.5 - 2 cm). Coupling with my Nokia Lumia 925 and a Samsung Note 3 worked fine. Also reconnect / Neukopplung is easy to accomplish.
### Incoming calls ###
The call is accepted via the central button on the front side. However, the incoming caller is fairly quiet to understand already in city traffic. Even the highest volume level (talking the Vol + button several times) has a barely adequate volume more than in urban traffic. The amazing thing is that the voice prompts of the Nokia navigation are much louder to be understood. An adaptation of the volume directly on the Lumia brought unfortunately unsuccessful. Confirmation of the discussion participants was the fact that my speech intelligibility was again very well transmitted to the caller.
### Outgoing Calls ###
Double-clicking activates the voice control of my Lumias. One must then wait briefly cracking in the FSE and then selecting a contact via voice control is possible. When talking going too fast, comes with the mobile phone, the call command not to complete. Works with Nokia Lumia very well, so you can get over the lack of display on the FSE, especially the Nokia Conversation yes again speaks the callers name and you have to confirm this with "Yes" before dialing.
### Charge & battery ###
Here I have a separate battery charger Nokia AC-3E (about 6 EUR) ordered me, for charging the FSE in operation is neither sensible (cable field) yet possible due to the low cable length. As used herein, a Nokia 2 mm hollow jack, you can not rely on its various mini and micro USB standard power supplies, unfortunately. However, it should be noted in this regard that a charge on the home network for the AC-3E is completed in less than 2 hours. The stand-by times, I can not say much, I submit here but to be happy.
CONCLUSION:
+ Reasonable price
+ Adequate processing
+ Speech intelligibility in conversation participants
+ Interaction FSE with Nokia devices
- Low noise level (too low for motorway)
- Comes complete with proprietary power adapter connection only with Nokia optional possible at home
For about 35 EUR you get with the Nokia HF-210 FSE one of the more affordable yet high ordinary speakerphones. Must arrange it with the fact that you have to keep an eye on the state of charge and that you remember to turn on the FSE before each ride. For little riders who are mainly in the city on the road, a good and sufficient FSE.
