Two Hiby's. Two bad batteries. PASS.

Two Hiby's. Two bad batteries. PASS.

I own a Hiby R2 as backup DAP. It hasn't failed... yet. Found out about the history of battery problems after I bought the damned thing. I've bought a few other Hiby products (FD1,FD3 and FC3), none have batteries!

I had no idea, sorry to hear it.

You need to use harder tips such as azla sednaearfit short.

I have hard eartips, which are so hard you almost can't bend the stem on them. I've tried to put SpinFit CP800 on my FHE, and there's still not enough bass. It really annoys me that a lot of people said in their reviews that "it's definitely a basshead iem". I think they never listened to real basshead iem, or some other reason, but this one is definitely not a bass heavy earphones at all, compared to Tri I3 Pro or Audiosense AQ0 (in my opinion).

fearing the day my BTR5 battery fails me,
seems an ass to change or find replacement battery.

i guess in that sense, the semi-DIY Zishan DAPs have ease of replacing things is somewhat a blessing.

Here's a new one: CVJ River Dusk. Let's hope it's tuned like the CSA and CSN. Link:

Graph looks good.

I don't understand what they mean. What is the advantage? They still go further to the same contact

Lots of IEMs have this. It’s simply tubes that channel the sound from each driver separately.

Ок, thnx. Big picture showed opposite side drivers and looked like "we forgot put in crossover"

Yeah, that is a weird image.

Hello everybody.

Here is my humble opinion about the Hidizs MD4. Some IEMS with a bold tuning. Well, more like 4. Although one thing is the sound and another the frequency response graphs.

I hope you like it.

Lots of IEMs have this. It’s simply tubes that channel the sound from each driver separately.

It's the big plus of 3D printed resin shells over injection molded plastic shells. They can include a channel for each driver and (hopefully) tune them separately so there is no weird resonance effect for that drivers range of frequencies. Having the channels and mounting points for each driver built in to the shell would also simplify assembly. I suppose we will find out in five to ten years how stable UV cured resins are in the long term. Even for IEMs with metal shells, we will get to find out how stable the polymer substrate binding the graphene, nanotubes or supporting the plated beryllium is. It's going to be a monumental PITA if the plastics in all our older IEMs fail at the same time.
