Hama Multimedia Behind Neck Headset CS-498

Am somewhat dissatisfied with the product.
- The 'fit' seems not made for my head. Carrying the set reluctant.
+ The quality is doubtful in my copy:
- The microphone cover (can I see no structural features that would prevent the fall) groundless
- The microphone funktionierte- probably for this groundwater very quickly no longer, because the soldering of the part is extremely weak and no contact required to break.
Well, as long as it worked (5 days) was the sound of the handset and the Fct. Of the microphone in order.
