@theangelboy @OCC7N Thx guys for clarification. My HE-500 doesn't have this problem.

They are closed? I thought they are open? So is the noise normal? Edit: I'm sure they are open, maybe you mean something different.

Hello, i have an issue. My father noticed that if you press the headphones to your ears, there is a not really squeeking sound but a noise the headphones are making which is audible. Even when the hp are not connected. Has anyone the same phenomenon or should i contact the Hifiman support?

Sounds amazing, dude. I really like it also and even proposed my dad he takes my HE500 and i take his HE400SE. He didn't bite, lol. Where did you buy your cable, Forza Audioworks?

I see, so i assume it's close.

Which are better? 25 Ohm or 32 Ohm?

Ah yeah, i thought so. Will check it out.

Is there a way to see what Ohm i have?

Thanks. Will make sure to enjoy it :) I'm currently using a Mojo 2 with them. Sounds good.

I'm having a hard time to give them back to my Dad. I just wanna keep em.

Really? Thats great. Isn't the HE1000 a 1500 bucks headphone? Why are the HE400SE better than the HE1000?

I've bought the HE400SE for my dad. After listening to them i like them better than my Hifiman HE-500 (which cost me 500 bucks) The HE400SE have a little bit more air to them and the Bass is also very nice. Idk i just like them better. The sound is grand and transparent. Great Headphone.

I've just bought the K240 Studio for my Dad. All i can say for 70 bucks they are sounding good. Not as good as my HE-500 but hey those cost way more. Also they look beautiful and very sturdy.

I love my Akg K501 so i think i would enjoy the K812 Pro.

AKG K142HD were my first more or less better headphones which led me into the audiophile world so i have a weak spot for AKG headphones. I would really love to hear the AKG 812 Pro one day but I'm happy with my Hifiman HE-500 as it is.
