Hi, is the frequency response of the MH750 the latest version of the earphone? I've heard that there are two versions (older and newer) and both sound different. Thank you.

Try playing music on your mobile phone (has to be mobile phone) on max volume and then plug the headphones in it while playing. I had the same problem and this did usually solve that.

What do you mean?

This is also quite good channel, the guy records with binaural microphones in his ears. But sadly the frequency response somehow isn't flat.  

That is great! Thank you.     Just an ordinary youtube video, but a quality mic, and especially flat/balanced frequency response. I don't even mind if it was outside of the cars.   I would like people to throw here any kind of videos/recordings with good sound.. later I can make a nice...

I wouldn't even need microphones under the hood, just good microphone anywhere. If some youtubers would have a quality mic, it was intended for recording voice, so bright sound.  Where I am actually getting great sound is in games, for example Most Wanted 2012, which sounds actually amazing...

They don't have to mix anything. Even my 3 years old phone has ten times better sound quality.

I search for good recordings of cars for a long time and I can not believe it, but it is a common problem of the whole internet. There are practically no high quality recordings of cars. Even when I find a video with a title of ''sound'', the sound is just horrible.   This is the first real...

But why did you boost the bass with eq when you've just taped it to lower the bass?   I recommend trying to tape just the top vent and leave the back vent open, it lowers the mid bass, but the deep bass stays strong. Someone may like it.

Question about the mod with blocking the vents: The top vent should have a at least a pinhole, but I am getting really good results without it, so when the hole is fully closed. The frequency response seems almost straight from bass to mids, without any tilt. How much is the risk of damaging...

Did you find out what was the problem? I have the same problem right now.

They were probably fake. The weird thing tho is that they had their signature, the sound was very flat, bass went very low and the peak/sparkle in the highs, but the sound was lacking any kind of quality.

I meant that even if the frequency response was somehow horribly equalized, the actual quality of the sound was very very bad, like a 50 dollar headphones or something. And if I remember, there was no difference, no matter where it was plugged in. I sent them back after a few days of course.

It may sounds funny, but every, even high end headphone I've listened to here in czech republic sounds like 10 dollar crappy headphone. I will probably write some thread about it.

NOTE: Sorry for my english, it is not perfect :)   So, I think I can say that Sony had some problems making these, because they released some models, which are bass-light. I can tell that, because I have one. I bought the MDR-XB700 about 4 years ago, and it supposed to be my first nice...
