Compact 11g DAC/Amp for Mobile Use

The SMSL Idol+ is a portable digital-to-analogue converter and headphone amplifier that connects via Micro USB OTG to computers, Android phones, iPhones and iPads. It weighs 11 g and measures 2.25 inches long. The unit draws power from the host device and requires no driver installation.

For listeners who want a tiny USB audio upgrade

This device suits users who need a lightweight DAC/amp for earphones or headphones on the move and who can use a Micro USB OTG connection. It is not for buyers whose source only offers USB-C or Lightning without an adapter, nor for systems that require balanced output or desktop-grade power delivery.

192 kHz maximum sampling rate

The internal VT1620A USB controller and MAX97220A amplifier chip support PCM playback up to 192 kHz through the 3.5 mm headphone output. This ceiling defines the highest-resolution audio the Idol+ can process from a compatible source.
