30-day 100% Money Back Guarantee!  

A few headphones and speakers don't trigger stereo mode on the Treo when used with a stereo audio adapter (such as the Palm Headphone Adapter, Seidio's Stereo Adapters, and the Sedio InnoDock). Instead of a wonderful stereo sounds you are met with deafening silence or mono sound. This is due to the impedance level on your headphones/speaker isn't high enough to trigger the Treo to switch into stereo mode.

The Audio-out Coupler resolves this issue by raising the impedence level of you headphones/speaker. Simply insert this adapter in-line between the headphones and your stereo audio adapter.

Great idea, but...
User: Brian Weng, Mar 15, 2007
...why do they manufacture this so that you need to buy an ADDITIONAL adapter? So not only do you have this kluge-y chain of adapters and connectors to deal with, you have to pay another $6 for the privilege. They should have made the 2.5mm-3.5mm conversion in the unit itself. C'mon, people!!
Broke right away
User: Joe Salem, Apr 2, 2007
Pros: Worked for about a week
Cons: Broke right away
It worked ok for a while than it looks like the wires got loose and started making wierd sounds. Not very well made. It looks like it is the only thing that works to make the audio sound any good on my
Treo 700wx. It looks like I have to buy another one after i just bought this one.
Didnt solve the problem
User: Neall D, Jan 18, 2008
Pros: none
Cons: Doesnt function as advertised
In spite of the claims, this device did NOT solve the impedance problem between my headphones and the palm 755p. In other words, the phone incorrectly recognized my stereo headset as an earpiece, and sound came through only one side. This is the exact problem this device was designed to solve, and it didnt work at all towards this end.
