£35 looks like a very good buy for this one: the Headstreamer launched at about £90-ish, and a new-price $139–$140 DAC/amp would still usually sit well above this on the used market, so this asking price is comfortably bargain territory.
It’s well liked as a tiny, bus-powered asynchronous USB DAC/headphone amp that sounds clean and straightforward rather than flashy, which is exactly why it still has appeal for a desk or laptop rig. At £35, the main upside is simple value: if it powers up cleanly and the USB connection is stable, it’s an easy entry point into HRT’s sound; just make sure the cable and any needed accessories are included, since that matters more than cosmetics at this price.

HRT, or High Resolution Technologies, is an audio brand founded by Kevin Halverson, a notable figure previously associated with Muse Electronics, a company known for forward-looking digital solutions and high-end amplification. The brand emerged from Halverson’s vision to apply compact, cost-effective streaming technology to audio file replay, positioning HRT as a digital innovator in the early 2010s. While the exact founding year is not publicly documented, HRT’s rise coincided with the exploding market for digital audio streaming around 2010–2013.
HRT is primarily known for its music streamers and digital-to-analog converters (DACs), particularly the MicroStreamer and Music Streamer II, which function as high-performance external sound cards for computers, tablets, and smartphones. The brand also introduced the Stage loudspeakers, a modular, pro-audio-style speaker system designed for ultra-low distortion. These products emphasize compact design, regulated power supplies, and benchmark performance in digital audio conversion, making HRT a key player in the entry-to-mid-level digital streaming segment.
In the market, HRT occupies a niche boutique position, appealing to knowledgeable hi-fi buyers seeking affordable yet high-performance digital solutions. It is not a high-end luxury brand but is respected for delivering industry-benchmark streaming technology at accessible prices. While some of its products, like the MicroStreamer, have been discontinued, HRT’s reputation remains strong among enthusiasts who value its innovative approach to digital audio replay and its focus on practical, cost-effective design.
