HFA Modular Detachable Headphone Cable Beta Program

We’re looking for members of the community to test our upcoming modular detachable headphone cable and give us feedback on how we can improve the product before launch. This program will also act as a stress test to find manufacturing issues that may arise from active use. If selected, you’ll be provided our beta testing kit which includes…

Headphone Adapters

Audeze / ZMF Dual 4-PIN Mini XLR
Sennheiser HD800 Dual 2-PIN
Sennheiser HD600 Dual 2-PIN
Focal / Hifiman Dual 3.5mm TS
Dan Clark Audio Dual 4-PIN Hirose

Amplifier Cables

4-PIN XLR Balanced 8FT
6.3mm Single-Ended 8FT

You’ll have the beta testing kit for one week, at which point you’ll ship it to the next beta tester. We’ll send you a shipping label via email towards the end of your testing period.

If you’re interested, please fill out the form below and we’ll get back to you shortly. If you’re selected, you’ll receive a follow-up with more information on when you can expect your demo kit. We only use your information for the Beta Program, and if you’re not selected, we’ll discard your submission data.

We appreciate your consideration and value your feedback!
