5 out of 5 eggsGreat, inexpensive option to add to VoIP phones

Pros: Added this to our Polycom phones for those who had a little trouble hearing people. Many of our calls come from machine operators working on a factory floor where sound quality is poor at best. Our technicians are very happy with how well these helped on those difficult calls. I'm logging into Newegg now to buy more of them!

Cons: It would be nice if the device could adjust various tone levels like an equalizer does but then I guess it would cost much more. No complaints really.
