Audio Technica ATH-M50xSTS USB

From a Studio Best-Seller to a Ready-to-Stream StreamSet

Based on the acclaimed ATH-M50x foundation, the ATH-M50xSTS-USB adapts its core features for streaming and content creation environments. The concept is simple: keep a reference closed-back monitoring headset while integrating a studio-quality microphone and direct USB connection. This approach avoids complex setups and ensures sound consistency, whether speaking, recording voice-overs, managing a live stream, or handling calls.
Compared to a "classic" ATH-M50x, the major innovation is the integration of a flexible boom microphone with mute control, as well as an A/D converter supporting up to 24-bit / 96 kHz via USB. The result is a complete package designed as a production tool rather than just a headset with a mic.

Intended Uses and Creators

The ATH-M50xSTS-USB targets streamers, podcasters, videographers, trainers, and home studio musicians seeking a reliable, quick-to-set-up, and easy-to-use daily solution. The closed-back design limits sound leakage and improves focus, which benefits streaming (less microphone bleed) as well as editing, voice monitoring, or recording.
Thanks to the mic boom positioned close to the mouth and cardioid directivity, the voice remains clear and intelligible even in untreated rooms. It's a relevant choice if you want clean audio for conversations, live commentary, narration, or meetings, while retaining a true monitoring headset to check your balance and details.

Key Features: Clarity, Control, and Long-Term Comfort

Cardioid Condenser Microphone: Clear Voice, Less Ambient Noise

The integrated electret cardioid microphone is designed to prioritize the main source (your voice) and reduce side noise. Positioned at the end of a flexible boom, it can be easily placed close to the mouth, enhancing intelligibility and limiting ambient noise pickup. For quick live responsiveness, muting is immediate: simply lift the boom to activate the Mute by rotation function.

High-Resolution USB Audio and Sidetone

The built-in A/D converter ensures clean and consistent capture over USB, with sampling rates up to 96 kHz and resolutions up to 24 bits. For a more natural feel during exchanges, the sidetone function lets you hear your own voice in the headphones, with volume control accessible via a button on the left earcup. This feature helps prevent speaking too loudly and promotes steadier diction over time.

Two Sets of Ear Pads: Isolation or Breathability, Your Choice

Supplied with two types of ear pads, the headset adapts to your working style: the pads from the M50x emphasize isolation and bass response, while the mesh fabric and faux leather pads prioritize airflow to improve comfort during long sessions. The closed chassis and 45 mm wide-aperture drivers (rare earth magnets, aluminum-coated copper wire voice coils) offer extended response, solid low-end presence, and useful precision for monitoring and voice control.
