Mono USB-C headset for calls

The HP 8X217AA Poly Blackwire 3315 is a monaural on-ear headset built for voice communication. It connects via USB-C or the included 3.5 mm plug, so it works with laptops, phones and desk phones. The single ear-cup design keeps one ear open to the surroundings while you talk.

Dual cables and adapter extend device choice

A 7 ft USB-C cable and a 3.5 mm cable with a USB-C/A adapter ship in the box. The adapter lets the headset plug into older USB-A ports without extra dongles. Switching between a modern laptop and a legacy desktop takes only a cable swap.

Wired analog and USB audio limits

The 32 Ohm impedance suits typical PC and mobile outputs but will not drive high-power studio gear. Audio quality depends on the host device’s built-in DAC when using the 3.5 mm jack. The omni-directional microphone picks up ambient noise in open offices.

Questions about this item

Will the ear cushion on the 3315 monaural headset need replacing after daily use?

The on-ear ear-cup cushion is user-replaceable; Poly sells spare leatherette pads that snap on without tools.

What limits call time when the 3315 is worn for back-to-back meetings?

Because the headset draws all power from the USB-C or 3.5 mm connection, there is no battery to deplete — only physical comfort sets the practical limit.

How much heat or fan noise does the 3315 produce during all-day calls?

The passive 32 Ohm drivers and lack of active electronics mean the headset generates no measurable heat and has no fan or coil whine.
