What HiFiMan HE400se owners say

“The treble is still tamed, but the bass doesn't seem to roll off. Punchy and fun.”
— @onepieceatatime on YouTube
“they are amazing, the replacement grills smooth out all the peaks and dips”
— @ZdraveBass on YouTube
“Hifiman are known to last about two months. It's only a question of time before they fail and customer service is bad from what I saw.”

What Sennheiser HD 650 owners say

“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!”

“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.”

“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”
