## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Good Value - but finding the correct setting is a pain
  

*by A***0 on Reviewed in the United Kingdom on 12 February 2020*

The headset eventually does the job, but finding the right setting means some serious feedback howls. Make sure the person you are using for the set-up call knows what is going on.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect!
  

*by E***G on Reviewed in the United Kingdom on 3 February 2020*

Good quality. Hard to find right setting at 1st but now I have had no issues with it.

### ⭐⭐⭐⭐ 







  
  
    Fabulous piece of equipment
  

*by K***L on Reviewed in the United Kingdom on 14 December 2018*

Does the job better than phones twice the price. Wire from phone to earpiece a little short but still great value
