The JCALLY JA3T is a compact USB-C to 3.5mm DAC dongle that gives phones and laptops back a headphone jack, with its own DAC chip doing the conversion. It is an easy add-on for anyone with wired earphones and a modern phone, or a spare for the laptop bag.
Who the JCALLY JA3T is for
Phones without a headphone jack: It plugs into the USB-C port and restores a 3.5mm output.
Wired IEM, earbud and headphone users: It works with wired IEMs, earbuds and headphones alike through its 3.5mm output.
A laptop-bag spare: It is a sensible backup to leave in a laptop bag.
Keychain carry: It is small enough to live permanently on a keychain or in a pocket.
Skip it if: Your phone or tablet has a Lightning port; the JA3T is built around a USB-C input.

JCALLY JA3T vs similar options
vs EPZ TP15 Lightning: Takes a Lightning input instead of USB-C, so it is the pick for Lightning-equipped iPhones and iPads; choose the JA3T for USB-C phones and laptops.
