The SBH20 has MH750 speakers that are different than MH1 , at least the diameter and the housing are larger. I suspect that at MH1 what happens is kinda  related to driver flex. I have the MH750 with the MW600 bluetooth and never had any problems. The biggest advantage of our headsets is that...

Well, yesterday they played perfectly for the whole day on my laptop or my phone. For what they cost, I could just buy a new pair or get used to this behaviour. Damn, they worth every penny for that bass, I almost prefer them over the much expensier Monster Turbine Pro Copper! But I really hate...

And the voodoo continues: this morning I played music on my MH1c  for 4 hours on my laptop in perfect condition and when I went out for lunch after 30 minutes connected on my Xperia T phone the rigt channel faded out again. Now I remember that happened before at my phone, but never in my laptop...

No,I did not modify them. And also I can't tell that I used them at high volumes. Only once I tested them with Fiio e07k but they worked ok after that.

After 2 months of perfect function , the right side speaker is playing at half volume than the left side. Strangely, if I let the MH1 unused for a day for a while I hear again both sides at the same volume for 15-30 minutes , until the right speaker again loses volume. 

Now I have them both, after I bought the DT770. My  first impression was that DT770 has too much treble, but after 2 months I enjoy them more because of the detail that the treble adds (possibly the mids too). Comparing to ATH-Pro700 they are much open, bright and at low and moderate volume the...

I didn't expect that 80 ohm vs 64 ohm (ATH-Pro700 are nowadays 64 ohm, not 32 ohm as they use to be) would matter so much connected to an E07K that suppose to drive well till 150 ohms ! My guess is that ohms combined with SPL will give that low volume.

A friend of mine just wants to sell his used (but in excellent condition - 6 months old)) Beyerdynamic DT770 Pro 80 ohms for a half of the new price. I have tested them for 5 days against my 3 months old Audio-Technica ATH-Pro700 MK2 64 ohms connected on Fiio E07K and I cannot decide if I want...

Why didn't I think about this till now? I measured them with a good Fluke multimeter and it shows 61-65 ohms, I guess the variations are coming  from the contact points accuracy. So, the answer is 68 ohms. I am still curious about the commercial truth, since there might be some people that buy...

  Well, check the Audio-Technica Central Europe (Budapest-Hungary) answer about the 68 ohm version :   Thank you for choosing Audio-Technica product. First, I would like to make it sure that your product is genuine. Soundcreation is one of our best resellers in Romania. We are 100% certain...

Would a Fiio E07k alone connected to a laptop feed ok the HE-400 ?

One sign about being harder to drive was when I connected them to the phone(Xperia T), at max volume they sounded a little distorted, but not in a bloated way like my former Sennheiser HD212Pro. One step down on volume and all was ok, but my Monster Turbine Pro Copper (16-32 ohms I guess...)...

My problem is not if they are genuine, but more like how does this affect the advertised sound since I did buy them only based on what I read from others and I do not have another 38 ohm version to compare. I mean, I would like to hear about the 68 ohms version that it retains all that quality...

I also received today an ATH-Pro700MK2 with a 68 ohm sticker over the original 38 ohm package imprint , but the 68 ohm is also written(not overwrite or sticker) on the Instructions/Specs paper included in the package. I don't know if I must be worried since there is no official 68 ohm version on...
