The best mic I have had so far the sound quality is amazing
Style: QuadCast 2 S, Style: QuadCast 2 S
This is a USB like and the sound quality is amazing. It’s a great price for what you’re getting it’s got some weight to it. The build quality is amazing. It’s compatible with almost anything given that it’s a USB Mic

Crisp mic
Style: QuadCast 2 S
A great mic. Captures my voice with crisp quality. My only grievance is having to set how much it picks up every single time I use it.

Fantastic USB Mic for Gaming, Podcasts & Content
Style: QuadCast S
I’m really happy with this HyperX QuadCast S USB microphone, it delivers clear, rich audio whether I’m streaming, recording podcasts, or chatting with friends. The RGB lighting is a fun visual feature that adds personality to my setup, and I love that it’s customizable via software.
The built-in shock mount and pop filter help reduce background noise and bumps, so my recordings sound much cleaner without needing extra accessories. The tap-to-mute sensor and LED indicator are super convenient for quick control during streams or meetings.
It’s also very easy to set up, just plug in with the included USB-C cable and you’re ready to go on PC, PS4, PS5, or Mac. The multiple polar pattern options give flexibility depending on what I’m recording, and overall the mic feels solid and high quality.
This makes a great gift for any creator, streamer, or podcast host, both functional and stylish. Highly recommend!

It's fantastic. It's just not quite perfect.
Color: Black, Size: Full Size
Update after almost 2 years of ownership:
I've gotten very used the the height of the full height keyboard wrist rest. I can't go back to a smaller one. It's super comfortable. I bought a second one for work and 2 mouse wrist rests to go along. All of them are built fantastically. They clean easily. If something happened to one of the ones I already have, I would come straight back here to buy another of the same one. On point #2 in my original review below, I still wish the edges weren't tapered so much, but I have gotten used to it. I gave in and offset the wrist rest from the keyboard. Not ideal, but it gets the job done.
Bottom line: would recommend any time.
Original review:
The build quality is good. The fabric is nice and soft. The bottom keeps it from sliding. It seems great, overall. I have only 2 problems with this thing:
1. It's too thick. I should have gone with the thinner one. Maybe it'll wear out a bit and my hands will lower into a position with which I'm more comfortable.
2. The left and right sides taper off. It's fine that the front and back do, but having the sides tapered means that if I center this along the bottom of my keyboard and rest my hands to type, my left hand is partially sloping off to the left side, off of the rest. Obviously this is easily fixed by sliding the rest to the left of center, but I've got a compulsion about things lining up and this really really digs into my brain badly.

By about last year I started looking at more pricey wristpads like the leather wrapped ducky and several other imitations online
Color: Black, Size: Full Size, Color: Black, Size: Full Size
I've been using Grifiti wristpads for a few years now at home and work. I buy a replacement every 6/9 months due to them getting absolutely filthy and having the top fabric falling apart. By about last year I started looking at more pricey wristpads like the leather wrapped ducky and several other imitations online. I decided to wait and at one point heard of Glorious although I was on a new set of Grifiti's so didn't think a lot of it.
So the time came for new pads (once again!) and when I was checking for alternatives to the Grifiti (and the Leather from EliteKeyboards, Ducky, Filco, and other wristpads -- sheesh, I'd think I was talking keyboards there with names). Then I came across the Glorious and recalled its a higher quality wristpad so I decided to order a full and compact to use at work. Definitely very happy with them so far and by 6 months and a year then I'll see how they hold out.
Pros:
* Cushion-y soft great for resting and supporting wrists, hands, or an arm on
* Firm without being too hard or soft
* Cloth wrapped so they're not going to wear apart like a Grifiti
* Cloth is sewed to the base and not glued by inspection
* Doesn't slide, there's a textured non-slick rubber on the bottom. Great on my work desk!
* Good price, the leather imitation glued to a base starts at $30+ dollars and they go up to $70
Cons:
* None so far!
I'll be buying 1 more for home use in a month as im using both full and compact at work. The compact size matches up well with my mouse pad there although you may want to measure if you do this. May Gaben be with you!
