Many of the newer headphones like planar magnetics need more wattage than the average headphone amp can deliver. Have you been wanting to find out what those headphones sound like with the extra juice from your speaker amp? Wonder no longer, the Zynsonix speaker amp to headphone converter box delivers the wattage to your ears in spades with top notch parts like non-inductive resistors, high-purity wiring and Cardas silver content solder to ensure the best sound quality. 

This unit includes protective protective components mandatory for tube amplifiers with output transformers to present a load and prevent shorting, and will assist in protecting headphones from excessive wattage from solid state and OTL amplifiers (within reason). All units now include a brass and dark blue emblem (see images). If you need multiple headphone outputs, please see the deluxe version

ATTENUATION BYPASS SWITCH: If you are using low sensitivity headphones such as HifiMan HE-6, HE-6SE, Susvara, HEDDPhones, or the Abyss headphones, you can add a switch to bypass the internal attenuation in the box. Bypassing the attenuation can damage normal headphones, contact me if you are not sure. 

Note: If using the 1/4" headphone output, please ensure your amp has a common ground. Contact me if you aren't sure. It's pretty easy to test with a $10 multimeter or you can simply ask the amp manufacturer. Nearly all amplifiers share a common ground. Also note that excessive wattage (turning your amp volume way up) can damage your headphones, so always be mindful of the volume.

*This product is made to order. Please expect a turn-around of about 6-10 business days.
