I'm speaking of phasing between drivers in the unit, not overall polarity. I agree that is an issue as well but that is generally far more pronounced. Throw the BQ3 on REW or ARTA and look at the phase diagram and you will find what I am referencing.

Ah. That's one of my concerns for multi-driver model. Either the wire is simply not connected (or got disconnected on transit or after some use) or wrong polarity or the driver is dead.

Now I remember one of the reasons why I prefer chi-fi with less drivers.

So I just got this Meizu HD50 and I am confused about the sound. Compared to ANY of my other headphones the treble on these sounds really really bad even after 15+ hours of burn in. It is seriously muffled. The bass and mids are there and I hear no distortion but the high frequencies seems like they're simply cut off from a certain point up.

Is it a common flaw that a headphone is missing the treble?
Is it how they're supposed to sound?
Or Is it possible that the drivers they're blown in some way that affects higher freqiencies only?

If someone here heard them please share your experience.

The HD 50 is just crap. I review it 2 years ago and it's really bad headphones. Go superlux !

 

[Sonnycz]

Yeah, looks like it really is. It sounds like Marshall II :/. And thanks for a tip.

The HD50 uses a biofiber diaphragm. It’s overall sound is pretty mediocre. Like you said, the treble is the problem.

The build quality of the headphone is amazing on the other hand.

They make great donor headphones for driver swaps because of the build quality.

I agree, physically HD50 is absolutely great ! And the case is superb too.

I have a long time broken Audio-Technica ATH-ES55 and AKG K450 in my drawer. Should I swap one of those ?!

Sure, whatever you want. It just has to be 40mm. Also, you have to keep an eye on the depth of the driver, as well as the width of magnet on the back of the driver. The stock driver is a pretty tight fit inside the cup.

I used some triple diaphragm drivers from Aliexpress. It almost fit. I ended up having to shave a bit of the plastic off of the inside of the driver cup that was hitting the magnet.

It will be different for every driver though. Some drivers will fit fine. You just have to try one.

The good thing is the HD50 is very easy to open up and work on, so you won’t hve any trouble.

Also, I’d recommend these threads for the HD50:

Ok I'll see what I can do. But I think I'm going to end up having a professional do it for me .

The CCA C10 continues to impress. After 24 hours burn in I think these are going to be my new #1 IEM. Mind you, I have the **** coming soon......

Agree too. They need burn in and seems very awesome for this price. Different tuning of ZS7, more aerial but interesting

I haven't heard the ZS7 but the C10 is way better than the ZS10 IMO. It's worth trying different tips, I'm using Spiral Dots at the moment and I will give Spinfits a try as well.

I love both equally the same since they are two different beast!

The C10 is balanced and lively, while the **** is neutral and natural

My MH755 arrived today and I have just finished taping up the longer side of the J cable... not pretty but at least I can use it now. Meanwhile my husband is in the kitchen doing something more serious to his pair...
