Headphones
These earbud headphones are the perfect accessory for
your Trellis M4 - they've been tested to work with our
modules - but can be used with any iOS or Android
device that uses a TRRS pinout. The buds themselves
are 16mm in diameter with a nice 40" long cable. They
come with a standard 4-pole TRRS headphone jack and
have a small microphone for recording audio samples
on your Trellis M4 (or for making calls on a mobile
phone).
