Does it work with both iPhone and Android?

It connects over Bluetooth or a Type-C cable to phones, tablets and computers. Bluetooth codecs like LDAC and aptX Adaptive depend on what the source device supports; iPhones top out at AAC over Bluetooth.

Can it drive high-impedance headphones?

The balanced output is rated at 220mW, which covers most portable headphones and many full-size ones. Very high-impedance or low-sensitivity models may want more power.

How long does the battery last, and can I replace it?

The 3.7V lithium battery is rated for up to 7.5 hours of playback and is detachable, so you can swap in a fresh one instead of retiring the device.

What audio quality do I get over Bluetooth versus USB?

Both paths support 96kHz audio. Bluetooth adds LDAC, aptX Adaptive and aptX LL when your source supports them; USB is the more stable option for desktop use.

Can I customize the sound?

Yes. It ships with eight retro-inspired presets, and you can build your own tuning through the app or the web interface.

What comes in the box?

The device, its detachable rechargeable battery and a Type-C cable for wired use and charging. Check the listing for any additional accessories.
