SAVE 50% on this HRT HeadStreamer Mobile, the most affordable HRT streamer yet, a perfect partner for listening to better quality audio from your Mac, PC, iPad, Surface tablet or a Samsung Galaxy S ll or lll phone, etc.
What is it?
This music streamer is basically a USB powered external sound card containing a very high quality DAC (digital to analogue converter) and headphone amplifier, designed to work automatically with your computer or phone (including PC, Linux, and Macintosh computers, iPads (1, 2 & 3), Microsoft Surface tablet and the Samsung Galaxy S ll and lll phones).
Why use HeadStreamer Mobile?
The sound cards featured in most computers and headphones outputs on most phones and portable players are a tick on the features list but are rarely if ever designed principally for excellent sound reproduction. Head Streamer Mobile fixes that by decoding the digital data from your computer, phone or tablet into the best possible sound for headphones listening.
Easy to set-up
Like other HRT models, setting it up is easy and quick, simply connect the USB cable (included) from the USB input on HeadStreamer Mobile into any available USB port on the host computer. Using it with your iPad (1, 2 & 3) requires HMA-1 adaptor (included). Use with Samsung Galaxy S ll & lll phones requires Host Mode cable (included).
HeadStreamer Mobile automatically performs an "electronic handshake" with the device connected, sends it the audio signal, and you're ready to listen with any suitable headphones connected to the 3.5mm jack headphones output.
LED indicators show the current sample rate (32k, 44k1, 48k, 88k2 & 96k), as well as the state of the HeadStreamer Mobile's mute circuit; you will always know at a glance your system's operating mode.
Stream all your music
Use HeadStreamer Mobile to play music stored on your phone or computer, including music stored on iTunes, Spotify, Windows Media Player, internet radio and play music from CD in your computers optical drive. In fact, you'll never need a stand alone CD player again as HeadStreamer Mobile does such a good job of making your computers CD drive sound fantastic.
If you happen to have high resolution music files (up to 24bit/96k) stored on your hard disc, you can play these through HeadStreamer Mobile as well in their full native resolution (no up-sampling).
How does it sound so good (the technical bit)
Utilising a minimalistic but extremely high-performance circuit that includes strong power isolation from the host device, HRT's proprietary asynchronous data transfer for lowest possible jitter, and a digitally controlled analog volume attenuator (the master digital volume slider on the host device causes the analog circuit inside the HeadStreamer Mobile to adjust the volume up or down), the HeadStreamer Mobile allows a level of sonic performance that until now has been unobtainable in its price range.
Although best suited to powering low impedance, high-sensitivity headphones, the HeadStreamer Mobile, which is equipped with a 3.5mm stereo mini-jack for its output, is able to drive higher impedance, less sensitive models as well, with the only compromise being a reasonable limit to ultimate volume level, not sonic performance.
If used with a male 3.5mm stereo plug-to-RCA adapter cable, HeadStreamer Mobile is also capable to act as a single-input, (analog) volume-controllable, line stage preamplifier that connects directly from a computer, tablet or phone to your personal entertainment system or powered speakers.
As firmware improvements become available, HRT's UpStream utility allows the HeadStreamer Mobile to be updated right from a computer's desktop in a matter of seconds.

21 Apr 2016Good value, found cheaper on Audioaffair than anywhere else, sounds graet with my Audeze headphones
16 Jul 2014Very happy with this and service provided. Very easy to set-up, just plug in and select as sound device. I use mine with Sennheiser Momentum headphones to listen to flac files etc. Shame its not as small as the HRT Microstreamer, but can't complain when it sounds so much better than coming out of the sound card directly.
