I bought the stinger as a stop gap for temporary use when away from home. They were truly awful but for £35 or whatever they were that was always going to be expected. even spending just £30 more would have reaped so much more quality and given close to top end performance. Which isn't surprising because £35 headset £30 of that will be shipping, distribution and manufacturing and retailers costs so it's a £5 headset. Whereas a £65 headset will have had at least £20 spent on the actual parts so 4 times as much.
My current headset is end game.

I would say it's much better going for the higher end hyper X headsets they are a lot better. Especially the clouds. The stinger and stinger core aren't great they are probably the best for their budgets but it was a huge step down from what I am used to.
