Nice work, thanks for pics. It seems it already a complex design with all those vents and directing of sound in chamber with two different full range drivers.

@Baycode Thank You Very Much for your pictures and Time.......Excellent. My wallet being itched more now!

Think the speakers are in series(and yeah no x-over).....

Anyone B3 owner could compare to UE triplefi 10(aka TF10)? Just a high level comparison is more than welcome,no need to drill down the cores....TY in advance.

Nothing can compete for the quality issues of the tenore :P for B3 it's incomparably less...

@Baycode

LOL, I did the same with the gorilla glass while modding my Pro 2.

 

Great informative post as always!

Disassembling the Havi B3 Pro1 : Looking into the heart of an iem

Warning: Spoiler! (Click to show)

 

 

I want to share my journey after inspecting a driver problem on my B3 Pro1.

 

Left piece seemed slightly quieter on the 30-300 Hz range to my brain. So I got permission from Penonaudio that they can send me a free replacement if I open it and try to find the problem first. So thanks for Penonaudio for encouraging me.

 

Before opening it up I have measured the iem for different freq samples and really found that the left earpiece is quieter than the right (4-5 dB) on the 35-250 Hz range (yes I have a crazy hearing system).

 

And so the story continues...  I didn't find any driver wiring or wax related problems. So Penonaudio told me that I can send them the B3 for guarantee (replacement). But I have to cover the shipping (for sending them only)... They shipped back the B3 Pro1 to their expense. I have to thank them for their great service. They are standing behind their guarantee. They got my trust...

 

Also I did a conversation with Penonaudio regarding the driver issues of B3 Pro1's. They told me that there had been only about 4 units until now. So I am now content that the build quality across the production benches are not bad. Even the big companies like Audio Technica and JVC had this kind of issues... :wink:

 

 

So why not fully understand the B3 before sending? Therefore I have fully disassembled it in the name of science :wink_face:

 

 

My findings in the pictorial form is on the below:

 

 

I have accidentally cracked the glass while trying to open them-up:

 

 

 

Is B3 Pro1 vented ?: Answer is yes, but hidden under a glass ;)

 

 

 

 

 

 

 

After opening the backplate the drivers can be seen. I have lifted one of the drivers-up:

 

 

 

Front part facing the ear:

 

 

Inner part removed. Drivers are resting inside a rubber-like material:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I have listened to each driver. All I can say that they are not acting like a known bass and tweeter presentation. Their sound seemed to me like close to full-range speakers with different presentations. To explain it better I can use this example: Think of a different male and female singers (vocalists) inside these speakers. And the sound we hear is coming from the mixing of these singers. One driver is bass heavy, laid back, veiled while the other is on the opposite character. These two opposite characters creates something very special... 

 

 

 

Removing the filter from the baritone-bass driver didn't change anything on sound. So no room for modification here...

 

Look at the thick OFC used on the wiring.

 

In the end I am amazed by the simple yet effective inner design of B3 Pro1. It is also an "easy to mod" IEM. But the problem is: I can't see any possibility for modding inside the shell :biggrin:  And the sound is already excellent.... :wink_face: 

 

 

 

 

My new B3's from the Penonaudio reached my hands... 

New Havi B3 Pro1's now have Pro I designation on the red dots. Previously they were only putting a red dot sticker for Pro1's. I think after this thread they (Havi company) have seen the practical usage of the model name "Pro1" instead of "old version" or " first version":

 

 

Awesome pictorial! That must have taken a lot of time and patience - wow. Very interesting configuration.

Let me tell you some reasons which may help you decide:

1- Just check the Tenore thread, there are soooooo much more build quality and driver issues with Tenore ( you may not know but I am one of the victims) whereas according to Penon its only about 4 for the B3 Pro1 (some of them were also reported Inside this thread).

2- You pay apprx 56-59 usd for the Tenore and B3 Pro1 and you receive near to non existent accessories with Tenore while B3 Pro1 is packed with enough accessories (was mentioned in the first page).

3- You pay nearly the same price but Tenore has thin and cheap cable with a golden jack and especially "cable releif strains like a joke"! B3 Pro1 cable is kevlar with 30 braided OFC wires in each strand (which makes a thick ofc wire). Also cable is in "balanced form" (4 separate wires for cleaner and accurate signal transmission) except the terminating part which is a very good quality 90 degree golden mini jack. Also cable releif strains are incomparably better (stronger) on B3's.

4- If you bougt Tenore and if you're out of Japan (like me), you have no guarantee (guarantee is provided for Japan residents and/or people who bought Tenore from an authorised seller). So could I replace my bad Tenore? Nope!

If you buy B3 Pro1 from Penonaudio they provide a one year guarantee. They wanted from me to send the iem only. So in a small envelope it cost me only 3 USD (with tracking number).

5- And the last part, sound, simply B3 Pro1 is better (IMO).

Mine as well. I have to agree Baycode.
The Tenore sounds really good till the channel imbalance starts to show off (usually after 20 mins). But I prefer the B3 by miles as they don't have any quality issues and on top they sound even BETTER :wink_face:

post #1050 of 4002

Both my Tenore n Havi are in good cond... 

i love Tenore for pop, easy listening..

the Havi for serious serious stuff, like listening deep out into space. snorrzzz :P

 

If i have to pick one...i would go for the Havi.
