“i'd say go for the Beyerdynamics since their only drawback is their harsh upper register of the frequency and nothing else. For the money, you can't beat them!”— chrissb34 on Reddit
“dt 770 100% and hyperx quadcast microphone! Best combo ever and "cheap"”— NervousNobody666 on Reddit
“The long term durability of these headphones seems to really depend on the climate where you live. When I moved to Florida the humidity and/or heat really caused them to start deteriorating fast.”— Lord_swarley on Reddit
“What an incredible difference they make to everything I had before! You can listen to a track and hear subtle details that you did not even know they existed. Wow!”— @marco83 on YouTube
“HD650 with a bum driver, but I was able to solider the voice coil back on, so they work normally again. I had a pair 15 years ago and always regreted selling them.”— kindofbluetrains on Reddit
“I find the HiFiMan Sundara & the Fiio FT1 Pro both more useful for mixing - the Sennheisers have a much more condensed/flat sound with less bass extension than either of those”— @reallyoldcob on YouTube
