Closer Examination, Build Quality, and Comfort

In terms of design, build quality and comfort, the Corsair HS70 Bluetooth is nearly identical to the rest of the HS gaming headset lineup, which is a good thing as Corsair's headsets grouped under that name have continuously proven to be well built and very comfortable. Because of that, I can only rehash what I wrote in my previous reviews and point out the few differences of the HS70 Bluetooth compared to rest of the lineup.


If you've seen any of Corsair's HS gaming headsets, you've seen them all. With that in mind, the Corsair HS70 Bluetooth is instantly recognizable because of its simple, clean, and very likable design which looks as good as it feels in your hands or on your head. Corsair really nailed the aesthetics and build quality, so it comes as no surprise that they're sticking with what obviously works.


The ear cups are made out of sturdy plastic and feel very nice when handled. The central part of both ear cups is covered in black metal mesh, which might trick you into thinking that the ear cups are based on an open-back design. They are not. Like with most other gaming headsets on the market, the ear cups are completely sealed, which means you don't have to worry about the sound of your games, movies, or music leaking out. The passive noise isolation isn't as strong as with some other closed-back headsets, which is good news if you don't like your headphones forming a very tight seal with the sides of your head.


The ear cups are connected by a metal headband reinforced with aluminium. The hangers are also made out of metal. The Corsair HS70 Bluetooth looks and feels just as premium as other headsets from the HS lineup.


The outer headband is decorated with a fresh and subtle-looking Corsair logo. Its inner side is decently padded and quite wide, which helps with weight distribution and overall wearing comfort. Both sides of the headband are covered in pleather.


The ear pads are filled with memory foam and covered in pleather. They completely surround my largish ears and don't clamp the sides of my head too firmly. The ear pads cannot be removed or replaced.


The ear cups are suspended from a pair of hangers, giving them a certain degree of freedom of movement. This is yet another feature which improves wearing comfort and makes the HS70 Bluetooth perfectly usable for longer gaming sessions.


The height of the headset can be adjusted by sliding the ear cups up and down its metal frame. Corsair didn't forget to put appropriate markings on each side, and they are clearly visible. There's a grand total of eight "steps" of movement on each side of the headband.


The left ear cup contains an analogue volume knob, a microphone mute button, USB-C port (battery charging and PC connectivity), and 3.5-mm jack plug. The microphone offers no visual indication for when muted, which would definitely be useful.


The left earcup is also equipped with a plug for the detachable unidirectional microphone. It's designed such that turning the microphone the wrong way is impossible.


The right earcup has a power button. If you want to use Bluetooth connectivity, you have to turn the headset on. This button is also used to pause music and answer/drop phone calls. Both of those actions are done with a single press of the button. Corsair's user manual claims that double-clicking the power button will skip to the next track, and quickly pressing it three times will return us to the previous track, but I wasn't able to get any of that to work. No matter how fast I clicked, double-clicked or triple-clicked the button, it didn't do anything other than play/pause the music and answer/drop phone calls.


The microphone arm consists of a series of metal rings that make it easily bendable, while having it stay in exactly the position it's adjusted to. The capsule can be protected with a pop-filter, which makes it look more professional, too.


Be careful when using the supplied analogue cable: Its gray side has to be connected to the headset, while the black side goes into a 3.5-mm jack plug on your device. It's a combined 4-pole TRRS plug, which means it works both as headphone output and microphone input. If you want to connect the headset to a PC sound card with separate microphone input and headphone output, you'll have to buy an appropriate splitter separately.


That's not at all mandatory, though. When connecting the HS70 Bluetooth to your PC, you should use the supplied USB cable as it is fully configurable in iCUE over USB; USB also avoids any potential issues with your integrated sound card, such as static noise or background hiss.
