Nickel seems to break the laws of physics. More power output than just about any portable solution on the market, yet smaller than some pairs of IEMs. Analog in, analog out. Super simple and clean. It’s like we took a kilowatt, kilobuck high end audio amp and shrunk it down like an angora sweater put through the hot wash cycle.

Over 25 mW per gram – yeah, no one else talks that way because no one else has as much power in as small and light a package.  Over 250 mW – a quarter of a Watt – per channel into 32 Ohms.  Nearly double that into 16 or 8 Ohms.  Plenty of power for just about any headphone out there.  And with 6.5 dB of gain, it’s a good bump up in level – without crushing the volume range of your phone.

Ultra-simple to use, plug it in to turn on, unplug to turn off. Add it to a cellphone and watch high-end personal music players run in fear. Hours and hours of play time, and mere minutes to recharge. Easily 8 hours of too-loud-to-listen output from a good set of IEMs (like our units), and 30 minutes to charge.  Oh, and you can charge at the same time you’re listening, thanks to a dedicated split power supply for the audio stage.  Designed for unmatched accuracy, built to survive the mobile lifestyle.
