Now, your own voice will sound as clear as what you hear without clunky clip-ons or wireless pairing. Installation is as simple as just plugging it into your headphones. The 10 mm condenser mic captures outstanding voice quality with a directional cardioid pattern that reduces background noise. You get volume and mute right at your fingertips, all on a single cable. Upgrade your calls, games, and streams with the HD 500 BAM. It’s the neat and easy way to turn your Sennheiser headphones into a high-end headset with brilliant audiophile sound.

Exceptional voice clarity
At the heart of the HD 500 BAM is a 10 mm electret condenser capsule with a cardioid pickup pattern, delivering exceptional speech clarity. The cardioid design rejects distracting noise from nearby fans, appliances, and people that would otherwise pollute the gaming experience.
Streamlined solution
For gamers accustomed to juggling headsets or relying on separate components for listening and speech, making the switch from listen-only headphones to an integrated microphone is no longer a burden. The HD 500 BAM provides a streamlined solution which can handle crystal-clear sound in both directions, whether in the heat of a match or a crucial Teams call.
Get volume and mute right at your fingertips, all on a single cable. The in-line volume control with mic mute switch gives you instant command over your audio without interrupting your workflow or gameplay.


Simple plug-and-play
Installation is as simple as just plugging it into your headphones. No clunky clip-ons or wireless pairing required. The HD 500 BAM seamlessly integrates with your Sennheiser HD 500 series and HD 620S headphones, transforming them into a complete headset solution.
To ensure flexibility across a vast range of devices, the HD 500 BAM uses a 4-pole 3.5 mm plug with CTIA wiring. A Y-adapter for PC soundcards with discrete microphone and headphone connections is included, along with three windscreens for optimal performance in any environment.
“Gamers have praised the extended comfort and immersive listening their 500-series headphones bring, but the lack of a microphone option meant compromise. With the HD 500 BAM, we’ve created a sleek, durable, and great-sounding way to level up your output and input. It is the perfect addition to your daily driver headphones, and a powerful accessory for anyone chasing a total audio upgrade.”
