First of all i did search and i could not find what i needed. the sound on my end is fine it is just the caller who heres an echo. are there any tricks to lowering the echo. this feature is great but the sound quality just isnt that nice.
thank you in advance for your help. 
Ehhh... short answer is "no"...the bluetooth sucks.
Long answer is that you can lower the volume output of the other party, but that makes it quieter for you too. There has been talk that if you lower the output volume on your phone prior to pairing with the unit that it helps, but I've tried it a dozen different ways with the same echoy results.
