Number of drivers has no correlation to the sound quality. There are plenty of IEMs with a single dynamic driver that are much better tuned than multi driver IEMs that are poorly tuned and/or have a poorly implemented crossover.
For the most part, it doesnt matter or people wouldn’t use beyerdynamic or AT 
for playing, im all for comfort over performance. 
i just use something “better” for mixing.
Etymotic makes really good IEMs if you can stand violating your earholes like that 
Hi guys, I’m reviving this topic as it seems to pretty much fit the bill for what I wanted input on!
I’ve also recently moved into an apartment so am also conscious of how loud I play. I’ve got a Rumble 25 so it’s easy enough to set the volume so it doesn’t break plaster off my neighbours ceiling… But it’s not ideal - thinking about how loud you’re playing can really distract you from what you’re playing 
I’ve got a Nux Mighty Plug Pro (tested alongside the Boss Waza Airs for bass and genuinely prefered the Nux!). Now I tend to use headphones a lot for other things so it’s not always the nicest thought to have to use them more when I want to practise - too long with any headphones and it’ll start getting itchy or feeling the pressure!
So I’m looking for some decent IEMs to practise at home with the Nux plug. I’ve never looked into them before so no idea what’s worth the price. I’m willing to spend up to £100, if necessary, and for reference my usual headphone go to is also open-back Sennheisers (flat EQ and great soundstage).
I see this brand about the internet quite a lot but since it’s mainly been from adverts I’m not sure if it’s legit or just crapware on a flashy website… Earphones | Hidizs
Any ideas? Or advice on what specs are the important ones to compare? 
Shure in ears are quite popular and not super expensive.
Flat monitors for practice might not be what you end up wanting. Flat means bass isn’t as pronounced as normal headphones or speakers etc. I dislike monitors for practice on bass
That’s a good thought! Don’t want things sounding too ‘cold’ I suppose. As long as its not a Sony level bass boost…
or Beats - tried that, don’t adivse, lolol
Flat monitors do work nicely with cab sims
Yep, better than actual cabs imo
Try the Truthear Hola for $20 USD
Funnily enough I’m actually waiting for Amazon to deliver exactly these today! 
After a bit more research and using Crinacle as a main reference I found the Moondrop Chu and this Hola were really well rated considering how crazy cheap they are. Seemed like a good starting point at that price, not risking wasting a bunch of dosh.
The Hola is reportedly a little more focused on the bass end so decided on that. Not expecting amazing things but if they sound good enough to practise with then mission accomplished! (until the next stroke of GAS)
Sweet, hope you enjoy them 
Pretty much all the chifi stuff is really good now and mostly just comes down to taste and the genre of music you listen to. The original Chu was the one of the best cheap IEMs, the only real con was it didn’t have a replaceable cord which they remedied with the Chu II. If you go up to $50-80 there are so many good options now! I’ve been thinking about getting the Truthear Hexa for a while but i have so many headphones/earbuds that i really don’t need more right now
