BYTECC TCB2 XLR to TRRS Smartphone Adapter with Headphone Jack

XLR-to-TRRS Smartphone Adapter

The BYTECC TCB2 is a compact Y-splitter that lets content creators connect a standard female XLR microphone to the 3.5 mm TRRS port on an iPhone or Android phone. A built-in 3.5 mm headphone jack enables real-time monitoring through a compatible recording app. The adapter requires no battery and draws power directly from the smartphone, so it suits mobile journalists, podcasters and streamers who need a lightweight, cable-free solution for on-the-go interviews.

Passive Gold-Plated Signal Path

Gold-plated, impedance-matched connectors preserve signal integrity without active circuitry, so the unit adds no electronic noise or power draw of its own. Because it is entirely passive, thermal output is negligible and there is no fan or circuitry to generate audible hiss during normal recording sessions. The short 10-inch cable keeps the assembly light at 0.05 kg, reducing strain on the phone's port while you work.

Sustained Session Reliability

With no internal battery or amplifier, performance remains consistent for the full duration of a recording session regardless of length. The adapter simply passes the microphone signal and monitoring return through the gold-plated contacts, so there is no risk of voltage sag, thermal throttling or sudden shutdown during extended interviews or live streams. Mechanical durability depends on the connector mating cycles rather than any electronic wear-out mechanism.
