Comfortable Over-Ear Gaming Headset

The Ruth's sister 857 is a wired over-ear headset built for comfort with an adjustable headband and memory-foam ear pads. Its sealed earcups use orthodynamic drivers and a ferrite magnet to deliver clear stereo sound. A 3.7 metre cable with an L-shaped 3.5 mm plug connects to any compatible audio jack. The set includes a microphone and inline volume control.

Suited for Long Sessions on 3.5 mm Devices

This model fits gamers and mobile users who want passive comfort and active noise cancellation during extended use. The memory-foam cushions and adjustable frame reduce pressure over time. Buyers needing wireless freedom or a USB digital connection should consider other options. The fixed 3.5 mm analogue plug limits use to devices that still provide that port.

123 dB Sensitivity Drives Loud, Clear Audio

At 123 dB sensitivity the headset reaches high volume levels from low-power sources such as phones or controllers without distortion. The impedance range of 33 to 100 ohms and 43 ohm resistance match a wide variety of 3.5 mm outputs. This single electrical characteristic determines whether the headset will perform well with your specific device.

Questions about this item

Does the 857 headphone come with a cable or must I buy one separately?

The 3.7 m wired cable is permanently attached and ends in a 3.5 mm L-bend plug, so no extra cable is needed.

Should I choose a different impedance version than the 33–100 range listed for the 857?

Only one version exists; its impedance spans 33 to 100 and works with any 3.5 mm audio source.

What does the 123 dB sensitivity mean when I plug the 857 into my phone?

At 123 dB the headphone reaches loud volumes with very little power from a mobile device.
