Setup, Design & Observations
Setting up a headset via jack is fairly simple, Plug into the headphone cable into your soundcard headphone/front panel or primary audio out, along with the microphone into your microphone port. In Windows, you may need to configure the headset via the sound options and set the desired sample rate in the advanced properties tab if not already done so.
The headset is very comfortable to wear with ideal clamping force, enough to hold the headset to your head, but without any crush. The earcups could be a little larger, as some may find them a little on the smaller side, though I had no issue. The tangle free cable is nice, some may prefer a braided cable, but supple, good quality 'non tangle' cabling is just as good. We find no modularity with this product which is a shame as a cable can limit the life of a headset. The inline remote is fairly unergonomic and is uncomfortable to use with your left hand, its positioning could do with being moved a little further down the line from the headset so it doesn't swing in mid-air too. That all said, it works perfectly fine for volume and mic mute.
The retractable microphone seems a little short, protruding by only around 100mm or so, and was a fair distance away from my mouth. On retracting the microphone, it seemed a little difficult to accurately push it back in without taking time to look or feel where it was going, showing a lack in refinement.
Listening to my music library on random presented Tori Amos' Beauty of Speed which is a mix of piano, vocals, bass and various percussion. Each note was crystal clear, the 50mm drivers clearly gave some expert precision. To confirm this early impression, I listened through a playlist of familiar tracks that would push the Force H3X to its limits. The 50mm drivers power some mind blowing bass, rich creamy and there while the mids and highs effortlessly glide through like a polished snowflake. DRXNES (aka drones) - 4evr ~ (plz) warms the heart, while Sabrepulse - Flux creates a party in your head. Cranking up the volume up to the max, the H3X certainly is capable of ear damaging audio that remains distortion free, if that is what you look for in a headset. At these levels there is a small amount sound leakage but at a more reasonable level it is barely noticeable so is unlikely to disturb those around you.
Playing a few matches on DOTA2, there is no sound unaccounted for, even in the thick of a teamfight, while in Battlefield 4, footsteps, explosions and gunfights are well articulated. This headset really throws you in the thick of the action the powerful balanced audio makes sure of that.
In Skype, friends described the vocals as slightly tinny but clear and audible. This could be due to the short microphone length meaning the microphone may have not been close enough to the mouth. There was little background noise picked up and remained decent throughout our gaming session. There was no audio leakage to report, something observed in both the Siberia and Echelon headsets which have retractable microphones too, which is a positive.
