Poly BlackWire 5210 USB-A Headset (TAA Compliant)

The Poly 8M3X1A6#ABA is a BlackWire 5210 USB A headset that gives professionals clear audio and dependable comfort for every call or meeting. It connects by USB A for laptops and desktops, and by 3.5 mm for tablets or phones, so you can move between devices without swapping headsets.

When you speak, the noise canceling microphone and built in Digital Signal Processing help callers hear only your voice, not the chatter around you. During a presentation or while listening to music, dynamic EQ automatically adjusts the sound profile to suit speech or media, keeping voices natural and music crisp.

Comfort lasts all day because the headband is metal yet light, and it adjusts easily to fit. Memory foam cushions covered in soft leatherette rest gently on the ears, so long sessions feel less tiring. Inline controls sit on the cord, giving quick access to answer or end calls, mute, and volume, which keeps meetings flowing smoothly.

The headset folds flat and slips into the included case, making it a practical choice for hybrid workers who split time between home, office, and travel. TAA compliance also makes it a safe pick for government or regulated environments that require approved equipment.
