Title: HAVI B3 Pro-1
Post by: ultrabike on June 12, 2014, 03:38:24 AM
Sound

I think these particular set has either a QA problem or something of the sort, so it might not be fair to judge these based on this particular sample. That said, this sample sounds weird. Very artificial, distant and low-fi. Imbalance issues all over in a weird way. Did not lasted inside my canal too long.

Comfort

Ok, nothing speshul.

Presentation

They look ok.

Price

$60 to $80 it seems.

Overall

This particular set is broken.

Thank you Ultrabike. I had a question, how do you get those measurements? Is it a computer program, or what do I need to do to be able to make measurements like you do?

I use a Focusrite 2i2 as the interface. The program I use is REW, though one could use ARTA or other SW stuff.

Huh, looks like some pretty steep rolloff at the top... I do remember people saying these were mids focused, guess they just meant the bass and treble were rolled off. :/

I didn't like these either.  Just weird, like listening to music in a deep but narrow cavern.

Red FR seems pretty accurate of what I am hearing. Mid range is skewed for some reason. Also there is certainly time coherence issue with two drivers.
Wont recommend it to anyone.

I recieved my havi b3 and subjectively they are awesome.  the mids make vocals extremely natural

Really? I thought they sounded pretty strange. Wonder how poor their QC is? Maybe good sound is hit or miss?

I would say try to get another pair of these to measure, maybe in some time I'll send my pair off for measruement and buy a second one because I do really like them that much.  Also, I am on my second set because the first set I bought from MP4Nation came, sounded really quite bad for a couple days, and then one of the drivers just exploded or something of the like.  It was that sound you get when your volume is turned way to high on a BA driver except for at all volume's.  Like a muttled digital sound where music was trying to fight through a wall.  Fortunately MP4nation replaced the set, and the second pair I got was WAY different and in a good way.  No driver mis-match to my ears, very clean and extended sound on both ends, and not in the way the graphs show on this thread.  I would guess quality control isn't the best based on my experience and this, but it's worth getting a good set because IMHO this challenges anything in the IEM world up to $300-400 if you like a neutralish sound with some extension on both ends and a slight upper mids treble tilt.

If I was aware of this Q.C. problems I wouldn't have bought them, unfortunatly they didn't arrived yet, so I can't say if mine is Ok...
The measurements looks horrible!

Anyway, looks to be almost as problematic as some Zero Audio IEM.

There's something wrong with it's soundstage, but I don't know what exactly, liked the rest though.
But IMO, Vsonic VSD3S is cheaper and better.
