Best Praise

“I mean the best gaming headset you can get right now under 100 is mh751 or mh752. I have the 751 and they are perfect. I’ve never had a headset that has done that with my voice but honestly I the only thing I can think of is maybe you’re talking too loud (I know that’s an incredibly stupid thing to say but still). But yeah basically mh751”

“Right ear cushion has become loose and therefore completely lost audio on the right side. I know 751/752 are top tier suggestion in this subreddit, just like 1 year ago when i started browsing, but tbh as fine as the headset works to completely break after one year is trash in my book. And if you read through some history in this subreddit there are a lot of people having issues with it”
