Unique Melody Miracle / Merlin / JH13 / JH16 / SM3 Reshell advice please!

im kinda in a similar situation like you, dont know if I should reshell my UM3x or just move onto customs.

i suggest you try the UM miracle , i am very satisfied with mine. it has very good bass, am not talking about quantity here, its something they call real bass ( takes control when it has to ). mids are very neutral and fluid.

send a PM to uniquemelodyaus

he is very helpful , if he has a universal fit Miracle , you might be able to audition .

Note : be advised the demo unit will give you a rough idea of how the miracle is, its not the complete package you will be getting :D

I'm pretty sure Joker has one or something

I listen to alternative stuff, electronic, and used to be listening to house/trance but since the SM3s i've stopped listening to the latter genre, maybe cos of the loss in punchy bass

Hmm...
When I think of my Miracles (compared to other IEM's and headphones) three factors come into mind.

1) tight bass

2) 'neutral' sound (come now it's really all just preference)

3) build quality

I listen to mostly pop/rock/jazz/classical/orchestra/house... and basically just anything else that catches my fancy. 

For bass, I would have to say that it's perfect - and not just for music.

For example. The other day, I was playing a thriller/horror game, and all was quiet. That is until something attacked me - at which point there was a slight rumbling in the bass, which definitely shook me to my bones. It was more than a 'omgthesuddenmusicstartledme' moment. It was legitimately because of the rumble that I felt so shocked - a deeeeep rolling. And that's when I knew for sure that my Miracles were all that they claimed to be (in terms of bass at least). 

As or sound, I can't say much except that it's good. Really, sound is all preference. You could love the sound signature of a Plantronics headset for all I know.

Build quality wise - be careful with your impressions. I have ONE regret out of all the steps to purchase my Miracle, and it concerns the impressions. 
Let me explain

Sure enough, come impression day I walk into the audiologist and sit down into his chair. We talk a bit and then he mixes the putty and starts injecting it into my ear - all good so far.

While he's injecting the putty into my ear, I'm sitting rigorously in my chair - not moving, with the 'mouth piece' inside of my mouth. - Still good.

A couple of minutes later, the audiologist carefully removes my mould - and says "These are great". Of course, I looked over them (didn't really know what I was doing) and they indeed looked perfect.

So I send them off, then a few months later the Miracles arrive in the mail. I put them in - PERFECT FIT, FANTASTIC SEAL

Then the next day, I put in my Miracles and go for a jog. But wait. What is this? Why is the seal so sloppy? 
It was only after a bit of thinking that I figured it out.

When you're sitting in the audiologist chair - you're natural tendency is to learn forward. When one sits in a chair to actually do something - it's unnatural to lean back.

THUS, the moulds in my ear took the shape gravity bestowed upon them - to create a seal when I'm sitting in a chair. So whenever I stand up, the seal is partially broken (a bit annoying)

Just my story and something that I think you should be wary of.

If there are discounts for remoulds in this special offer thing - I'll consider taking it.,

I don't think standing would be good. Just try to maintain a good posture when you're on the chair. Lean back (but not too back) onto the chairs backrest - and mimic how your body usually is when you stand. Most importantly, remember not to tilt your head too much. Try to keep it as parallel to the floor as you can.

You never close your mouth, Unique Melody do the open mouth impressions - where you open your mouth as you take  the impression. Generally, they will give you something to bite on, others will say to bite down on your knucles etc etc.

Yeah I've used the Miracles numerous times for jogs. Heavy ones at that, roughly 30 - 40 minute jogs where I'm sweating a lot. Unique Melody don't mention whether or not their custom IEM's are water resistant or proof - It would serve as a detriment to their warranties/guarantees, and from a business point of view I understand. But I still think that they should advertise that the IEM's are good to be used for light water activity.

Also - Isolation on the Miracles are fantastic. When I'm on a noisy train ride (in Australia), my Miracles combined with my J3 and some music will block out everything. Even without the music I don't think I'd be able to hear anything
