I’m not sure where the admin got £39.99 as the next best price from? These are the wireless version (Karius X are the wired version). Still a fair few sets for less then £35 on Amazon warehouse if anyone missed out. According to reviews they are pretty decent. Almost the same as the Karius pro but without Bluetooth connectivity. (They connect straight to the Xbox, or PC via Xbox dongle)
I bought a set of Razer Kaira X the other day from Amazon for £34.99 and would highly recommend. They're not that price now mind you. The black ones are £39.99 currently on Amazon.
I have but always nice to get some opinions from here lol. Geez (lol)
