Logitech H390 vs Poly Blackwire 3320 Comparison

Logitech H390

A bi-directional noise-cancelling boom covers 100 Hz to 10 kHz, and it rotates to either side. However, from a moderately noisy room, I'd expect listeners to find it clear enough, better than most headphones without a boom. Rotating the boom to either side helps left- and right-handed users on shared units.

Poly Blackwire 3320

The noise-cancelling mic sits on a 135 mm boom that rotates 280°, with a 100 Hz to 10 kHz range. However, among open-plan desks, I'd expect your voice to come through clearly from the far end, excellent for the price. A 135 mm boom with 280° rotation means left- and right-ear wearers are both covered without a special SKU.

Logitech H390

At 197 g, with padded swivel cushions and an adjustable band, it's comfortable for the price. After a long session, I'd expect the cushions to feel warm. That's fine for students and occasional callers. The adjustable padded band suits shared classrooms where head sizes vary. At 197 g it isn't featherlight, yet for three-hour seminar blocks it's adequate before the pads feel sticky.

Poly Blackwire 3320

At 131 g with foam cushions, it's light. The on-ear stereo design is comfortable for shorter stretches. Expect the foam to feel warm after a long session. At 131 g it's one of the lightest stereo headsets we list, so all-day shifts are realistic if you accept on-ear pressure. Foam wears faster than leatherette; keep spare cushions in the IT closet for a fleet rollout.

Logitech H390

The H390 is not listed with Microsoft Teams or Zoom headset certification. Mute is listed as Inline mic mute. A mute alert or indicator is included, so you can tell when you are muted. On-headset controls are listed as Inline volume +/-, mic mute. I'd look for a physical mute I can find without thinking, especially in an open office.

Poly Blackwire 3320

The Blackwire 3320 is listed as Microsoft Teams, Works With Chromebook. Mute is listed as Inline mute button. Call controls include call answer/end; Teams button on Teams variants. On-headset controls are listed as Inline: call answer/end, mute, volume, Teams button. IT can manage it through Poly Lens. I'd look for a physical mute I can find without thinking, especially in an open office.
