kingofdirtysouth: this shyt off the chain it works fine for my 650

cowgirlup53186: Works pretty good to me. Definately makes a BIG difference in volume level!Love it!!! Only downfall is it does randomly disable :(

magmax: I have no idea where some of these reviews are coming from- A 1.5 star rating posted to ask if it works with the 680? I mean, give me a break! I've used it with very satisfactory results in my 650 and I'm ready to install it in the 700p that replaces it. The sound reproduction is very good and it curves toward less than good on the high end of the volkume control because, let's face it the speaker on the 650 wasn't meant to go that far and yet it does!

ranielvalerio94: Does it work on treo 680?

devilish19: this program actually made my volume almost completely silent. the treo's natural volume is louder than this program.

Arbor: It works greatly! It has more than doubled the volume of my treo 650. Thanks alot!
