Still using Bluetooth for gaming? Are you nuts? When you want no dropouts, lowest latency, and best sound, you need an actual physical connection—and you need the mission-critical reliability of Hel+.

Insane Power and Detail

Hel+ lights up any headphone with 1.4W of power, while delivering every detail with a 32-bit ESS DAC. Just plug Hel+ in to any PC, Mac, PS4, PS5, Switch, iOS, or Android device, and you’ll get powerful, lag-free sound…while also sounding amazing to your friends with a podcast-quality microphone input with dedicated TI ADC.

Extreme Protection and Reliability

Hel+ was engineered from the ground up for mission-critical gaming. High-reliability USB-C connectors, quality Neutrik headphone jack, and exclusive custom high-match Alps potentiometer are just the beginning. We also include our exclusive over-current protection to eliminate potential problems with shorts or wrong connectors, plus integrated thermal protection, and extensive ESD hardening of all inputs and outputs. We’ve even decoupled the USB connections to eliminate most ground loops.

Go Beyond Gaming

Hel+ is also an amazing DAC/amp, with incredible flexibility. The high-end ES9018 digital-to-analog converter delivers exceptional sound. Connect to your computer via USB, your TV via optical, and create an entire system with powerful headphone output and versatile preamp output for powered monitors or external speaker amplifiers. 

Designed and Built in Texas

By “designed and built in Texas" this is what Schiit mean: the vast majority of the total production of the Hel—chassis, boards, transformers, assembly, etc—stays local. The chassis are made in California. The PCBs are done in Nevada. Yes, the UK wall-warts are made in China, but there's some give and take at this price point. 

3-Year Warranty 

Hel+ is covered by a limited warranty that covers parts and labour for three years.
