QPAD QH-90 Headset

qpad-q90

Introduction

QPAD, as its name implies, is traditionally a mouse mat manufacturer. These days though, you can’t be a one trick pony – you need to diversify; and that’s what QPAD is doing, branding itself out into the headset game. This latest offering, the QPAD QH-90, features a stark white colour scheme, super soft padded leather cushioning and a detachable microphone. Will the audio quality back up these features and will it be worth the price tag? That’s what we’re here to find out.

QH-90 Features

  • Hi-fi capable 53mm drivers for supreme audio quality
  • 15-25.000 Hz frequency response
  • Detachable microphone (quick and easy to plug/unplug for music-only purposes)
  • Solid aluminum construction for durability and stability
  • Super-soft padded leather headband and leather padding on cups
  • Closed cup design on QH-90 for enhanced bass-reproduction and sound leakage

Unboxing

The packaging for the QH-90 is really high end stuff. It’s got that lovely matt feel to it that gives a good first impression.

After removing the slide cover, there’s a second lid to remove, this one featuring the typical message from the founder of the company, congratulating you for being such a smarty that you bought their fine product. We shall see if that holds true.

All hardware comes wrapped in plastic as well. There’s a lot of crap to throw away with this after unboxing, but it should mean that you receive your QH-90s in near perfect condition.
