“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”

“Wife asked me what I wanted for Xmas and I was looking at the closed back sundara as a possible replacement for my HD569 for use on the Sofa. So sent it over but she stated she’d already gotten me my big present. So figured I would try and pick them up in January. But then this arrived. Nice surprise, looking forward to trying them out!”

“I ordered a brand new (supposedly) pair of Sundaras from HiFiMan's Amazon store, and upon opening the box I noticed white dusty stuff on the open back of the headphones, in the finer mesh material. I knew HiFiMan has a reputation for QC issues but I was not expecting *mold*. I contacted customer service about it and sent photos and microscope images. Here's hoping they have a good response. Definitely disappointed but I guess that's the risk you take.”
