He-400 impedance question.

post #1 of 7
Thread Starter 

Hey guys, I recently bought a pair of He-400s, an upgrade to my previous cans ATH-M50s.  I have the Magni/Modi stack.   My question is, I was hitting pretty loud volumes at around 9 to 10 o'clock with the ATH M50s which have an impedance of 38 ohms.  Now with the He-400s im having to go to around 1 oclock for the same volume, and they're 35 ohms... Is there something wrong with them? Additionally, I found their bass lacking in comparison to the M50s, better quality of course, but just no where near as present. I don't know if this is just because it's my first pair of open back headphones, or if it's part of a problem?

It's not the impedance, but the sensitivity that's the issue here.  The HE-400s have a fairly low sensitivity, so you need to apply more volume.

Thanks for the help, that's good to know :D Everyone talked about how amazing the bass was on these headphones, but I've been a bit disappointed, I've had to EQ it in, and even then it's hard to hear... Am I just retarded, or does the He-400 just have less bass than the M50s?

It does indeed have less bass than the M50.  Bass quantity isn't equivalent to bass quality though.  Even the HE-400's bass is somewhat north of neutral, but not as north of neutral as the M50 though.

Yeah, I can tell it's a lot cleaner and controlled... Just an adjustment I'll have to make I guess :P I'm still within the return period however, is there another headphone that might provide the bass I'm looking for? Maybe something semi open like the Denon AH-D2000, but around that $300 price point?  Sorry for all the questions, but thanks for the help! :)

The Denons will definitely provide the bass quantity.  I'm not sure what might bring quantity similar to the M50, although I hear very great things about the NAD Viso HP50.  You might check them out.  Nothing else short of the LCD2 will provide the quality of the HE-400.

I'm with you. I'm pretty underwhelmed so far with the HE-400's I got last week. I should have done a bit better research. They have bass, but they have no pace or punch. This is comparing them to many other headphones I have or had. They are so far to me just an 'ok' set of headphones a little boring. I'm going to give them a week or two to see if they grow on me. I can hear that they have detail etc, but there are lots of other headphones that I think are close or better in detail that provide a more exciting experience. My other issues with the HE400's is that I don't think the sound stage is all that great.

 

For example I much prefer the Sony MA-900 or Audio Technica a900x. They have a lot more depth to my ears. Having said all of that, I think listening to headphones a lot of what we hear is our brain 'filling in' the information we are looking for. Brain burn in..:) Perhaps I will grow to like them a lot more as my brain adjusts to them.
