FS: XENOS 3HA portable amp

post #1 of 6
Thread Starter 
The Xenos 3HA headphone amp is out of production, but it remains quite a remarkable item. It has three dials: for volume, bass, and treble, allowing the listener to vary the tone for different tracks or sources. There are two mini plug outputs so two people an listen at the same time. The unit has received uniformly strong reviews from users and professionals for its sound quality and value.

The 3HA works either with the included wall power cord or four AA batteries (not included).





Included in the package:
- Xenos 3HA headphone amp
- Xenos wall adapter
- Original padded box
- Bonus: RnB Audio "Sky Blue" cable, 8 inches long - beauty that looks as good as it sounds, generally thought to have a "refined" sound; perfect for the 3HA


The amp is in great shape, and works perfectly. $65 - PayPal is preferred. Includes priority shipment within the US. Read my feedback link, and feel free to send me a PM if you have any questions.

Listed on eBay

As promised, I relisted the Xenos amp on eBay. There still seems there's some posthumous interest, so PM me if you still want to buy.

Thanks!
