Know before you buy
The Groove features a high-performance integrated DAC and a dedicated amplifier that bypasses your device's internal audio hardware. This provides a significant power boost and cleaner signal, allowing your headphones to perform with greater clarity and dynamic range.
The Groove excels with high-impedance headphones, providing 71 milliwatts of power at a 300-ohm load. Because of its 21-ohm output impedance, it is best paired with headphones that have an impedance of 32 ohms or higher to ensure optimal frequency response and sound quality.
No, the Groove is entirely USB-powered. It draws power directly from your computer or mobile device, making it a true plug-and-play solution for portable high-fidelity audio.
The unit features tactile, rubberized volume buttons on the top of the chassis. It also includes an integrated LED display that provides visual feedback for your current volume level.
While it works with most standard 3.5mm headphones, its 21-ohm output impedance means it may not be the ideal match for very low-impedance in-ear monitors, which can sometimes sound colored or distorted when paired with higher output impedance amplifiers.
The Groove is larger and more substantial than typical thumb-drive-sized USB DACs, reflecting its high-quality build and desktop-grade internal components. While it is still compact enough for travel, it feels more like a premium piece of audio equipment than a disposable accessory.
