Closer Examination, Build Quality, and Comfort

The most obvious point of differentiation between the Thermaltake Isurus Pro V2 and a regular pair of wired in-ear headphones is the supplied headband. It's made out of a thin, flexible piece of steel and weighs next to nothing, which is why it needs no padding. The headband helps the headphones stay in place even when you're vigorously moving your head and enables you to conveniently hang them around your neck when not used.


If you prefer using the Thermaltake Isurus Pro V2 as a more traditional pair of in-ear headphones, you can effortlessly slide the earpieces off the headband. This takes around two seconds. You can put them back on the headband just as quickly. The headband has two holes that prevent the headphones from sliding off on their own. It's a simple and clever implementation that makes it extremely practical to use.


The earpieces are made out of plastic. They are fairly large and prominently stick out when inserted into the ear canal. The speaker tubes are angled and come covered in basic silicone ear tips.


Thermaltake supplied two additional pairs of silicone ear tips, one larger and the other smaller than the preinstalled pair. It is essential that you try out all three to find those with the best fit. This will determine the overall comfort of the Isurus Pro V2, but also has a massive impact on the sound performance. Speaking of comfort, I'd rate it as solid but not perfect. While I was able to wear these headphones over longer gaming sessions (2–3 hours) without experiencing pain, I always felt them to an extent. It's hard to say if I did because of their size, the angle of the speaker tubes, or the quality of the supplied ear tips. Either way, if you're looking for an in-ear gaming headset that will be so light and comfortable you'll forget you're wearing it, this probably isn't it.


The left and right channel are clearly labeled on the earpiece casings. The left earpiece also has a built-in omnidirectional pinhole microphone—Thermaltake's official website claims that the microphone is on the right earpiece, which definitely is incorrect. This is an interesting design decision as in-ear headphones usually have their microphone on the in-line remote control, which naturally positions it below the face when worn. My guess is that Thermaltake sought to avoid any communication-related issues caused by users rubbing or covering the in-line remote control with their clothes.


The in-line remote control is on the braided cable going from the left earpiece. It has three clicky, easily accessible buttons: volume up, play/pause, and volume down. The play/pause button has other functions as well, which for some reason aren't documented in the user manual. You can also use it to skip a song (double click), go back to the previous one (triple click) and answer/drop phone calls (single click when receiving or in a call). On the side of the in-line remote control is a microphone mute switch.


The headphones terminate in a 3.5-millimeter 4-pole (TRRS) plug. This is what you'll use to connect them to any device with a combined audio output and input (laptops, consoles, or mobile devices). If you want to use the headset on your PC, which most likely has a separate audio input and output, there's a splitter cable with two 3-pole (TRS) 3.5-millimeter plugs that will allow you to do exactly that.
