What the headset does and who buys it

The Acesori K2 is a blue over-ear wireless gaming headset built for PC and PlayStation players who want cable-free sessions. It connects by 2.4 GHz USB dongle or Bluetooth 5.3 and also works wired through a 3.5 mm jack. Xbox consoles are supported only in wired mode, so buyers wanting wireless Xbox chat should look elsewhere.

Battery life and where it stops

A 100-hour rated battery delivers roughly a week of typical play before a four-hour recharge is needed. Wireless range reaches 10 metres, so you can move around the room without drop-outs. While charging the headset operates only in wired mode and both 2.4 GHz and Bluetooth links are disabled.

The spec that decides fit

Dual 50 mm drivers with a 5 Hz to 20 KHz response and 96 dB sensitivity drive game, music and movie modes selectable on the headset. The boom microphone uses sound isolation for clear voice pickup. At 350 grams the set stays comfortable for long sessions, but anyone needing active noise cancellation rather than passive isolation will need a different model.

Questions about this item

Will the 2.4 GHz USB dongle work with my PS4 and PS5 without extra drivers?

The USB dongle provides plug-and-play 2.4 GHz wireless audio on PC, PS4 and PS5; no driver install is needed.

How do I know the 2.4 GHz link is active after I plug in the dongle?

Hold the power button five seconds until you hear "pairing mode"; a steady blue LED on the dongle confirms the link is locked.

Which cables and adapters are included, and what must I supply for Xbox wired play?

The box contains the headset, 2.4 GHz USB dongle, USB charging cable and 3.5 mm audio cable; Xbox Series consoles require the 3.5 mm cable plugged into the controller.
