Defendwe 2-in-1 USB-C to 3.5 mm Jack & Charging Adapter for Letv Le 2 X620

What it is and who it fits

This 2-in-1 USB-C adapter adds a 3.5 mm headphone jack while keeping the charging port free for Letv Le 2 X620, Le 2 Pro and Le X220 phones. It also works with Moto Z, Moto Z Force, Mate 10 Pro and Mi Max 3 handsets that share the same combined charging and audio interface. The integrated decoder chip handles digital-to-analogue conversion so audio plays through wired headsets without extra software. Compact black, silver, yellow, rose-gold or red finishes slip into a pocket for daily carry.

What it replaces and when to upgrade

It replaces the missing 3.5 mm socket on phones that route both power and sound through a single USB-C port, letting you charge and listen at the same time. The jump is worth it when your current dongle blocks charging, fails to recognise inline microphone controls or introduces static during calls. Plug-and-play operation means no driver installs; the adapter simply draws power from the port while passing clean audio to the headset.

Capacity and headroom

The adapter supports simultaneous charging and stereo playback for typical commuting or office sessions, with stable transmission speed noted by the supplier. It runs out of headroom if the phone demands high-current fast charging beyond the adapter’s pass-through capability or if the connected headset requires more drive voltage than the built-in decoder can supply. For those edge cases a powered dock or wireless headphones become the practical alternative.
