Listen to your music with McIntosh sound quality no matter where you go. Your headphones will thank you.

Nearly everyone walks around with most (if not all) of their music library in their pocket or bag, where it's readily accessibly via a pair of headphones. While convenient, it likely doesn't sound as good as it could. The handheld MHA50 Portable Decoding Amplifier can make your music sound its best - and likely better than you've ever heard it before - through your headphones.

The MHA50 includes wired inputs for Apple iOS devices as well as Android devices that are compatible with USB on-the-go technology, plus Mac and Windows computers. It can also wirelessly connect to these devices via Bluetooth 4.1 with aptX technology (Android devices that aren't compatible with USB on-the-go can still connect via Bluetooth). It features a high-performance 32-bit digital-to-analog converter (DAC) and supports 32-bit/192kHz Hi-Res audio and DXD384 files, as well as asynchronous USB audio. Its 3,000 mAh rechargeable battery provides up to 6 hours of playback on a single charge when connected via Bluetooth; playback can last even longer when using the wired connections.

Comparably sized to smartphones, the MHA50 is compact and lightweight for easy portability, with a beloved case that fits comfortably in your hand or pocket. Its sleek design features a glass front panel with a touch-sensitive volume control knob inspired by the classic knobs found on countless McIntosh products. It's built primarily from durable extruded aluminum which also has some inherent noise-shielding properties to help block external interference.

Two gain settings allow the MHA50 to work with all types of headphones from small in-ear models to large over-ear studio type designs like the McIntosh MHP1000 headphones (sold separately); it can drive headphones with impedances ranging from 8 - 600 ohms. Headphone Crossfeed Director (HXD) brings added dimension to your music in a naturaly sounding way and can be easily turned on and off depending on your preferences. All audio is output via a gold-plated 3.5mm jack. This jack can also connect to a pair of powered desktop speakers, allowing the MHA50 to serve as a desktop DAC.

The MHA50 comes complete with four USB adapter cables to connect various devices, a leather carrying case, and a wall-mount charger with USA plug and adapters for Europe and Japan.
