Hi-Res audio · USB-C & Lightning · pocket DAC
Spectra X2
Hear everything in the recording.
A cable-sized DAC and amplifier that turns any phone into a hi-res audio source. It drives demanding wired headphones cleanly and loudly — no bulky desktop amp, just the dongle on the end of your cable.

Three steps · nothing to set up
Studio sound, straight from your phone
Plug Spectra X2 into your phone
Connect the dongle to your phone's USB-C or Lightning port. Both cables are in the box, so it's ready the moment you open it.
Connect your wired headphones
Slot your favourite wired headphones or in-ears into the 3.5mm output. The built-in amp has the power to drive them properly.
Press play — hear the full resolution
Open any music app and listen. Spectra X2 decodes the file at its native resolution, so you hear the detail your phone alone leaves out.
What's inside the dongle
Small body, serious sound
A full DAC and headphone amp packed into an aluminium body no bigger than the plug on your cable.
On the move · late at night
The late train home, in full detail.
The carriage rattles, the lights are low, and your phone's own output flattens everything into a wall of sound. Clip Spectra X2 onto the cable and the track opens up — the bass settles, the vocal steps forward, the hiss falls away.
It's small enough to live in a jacket pocket and quiet enough for headphones at midnight. Plug in, press play, and the recording sounds the way it was mixed.
