Sennheiser - IE 600

Okay so I finally got them and for me I can notice some differences. What surprised me the most is the fit, with the IE600 I get a perfect seal with the standard silicon tips by just placing them in my ear gently every single time. This wasn't the case with the IE200 where I needed those orange tips. That was very weird since they look so similar. (Besides the different material of the casing) Regarding sound I would say the IE600 feel especially more detailed to me than the IE200. They sound great and I prefer them over them so far. But it's very hard to give details about this for me at this point. I notice these changes more significantly when I use a pair of headphones for a while and then change back, so I might still need some time with them. Also: I don't have a lot of experience with IEMs, the only other pair I own are the Dusk x crinacle and quality wise the IE600 are definitely closer to those than to the IE200. So far I absolutely love them and it was the right choice for ME. Would I recommend them to someone else? Probably not when you need to pay a couple hundred bucks more than for the IE200. If you don't care that much about money I would say go for it and try them some day, but if you're not getting a very good deal I think they're difficult to justify from a financial perspective. Still, you're getting amazing quality from them and they're awesome - as long as they work. Cause a lot of people are reporting about quality control issues and them breaking pretty quickly. I can't say anything about that so far, that's also something I still need to figure out with more time.

I bought the IE600 because as you said people liked it more and it was mid forward (with a bass boost) which I wanted for my tuning rather than hyper analytical like the IE900. But If my IE600 died and at the current discount I could get it for a change, you can always try and return it or sell it at some point if you don’t like it and get the IE600 again.

You should definitely check out the Sennheiser IE line. From their cheapest IE200 , their midrange IE600 and to the most expansive IE900 they are all amazing iems, with incredibly small shells. Small enough to actually sleep with, as they do not stick outside of the ear.

That's currently the closest option that we have. Ie200 and 600. Not that interesting from just the tuning perspective but as overall package it's just unbeatable. 

fiio fh3 > ie600 it’s so good i cried a little 😭

I’ve gone from using my iPhone with Moondrop Dawn to Chord Mojo 2 then to an A&K KANN MAX and now using an SP3000T. My iem’s are Truthear Hexa, Moondrop Aria 2 Red, Sennheiser IE 600.

When I moved up to the KANN MAX, that was the real game-changer for me. Suddenly I could hear all the little details in the track — way better separation — and it just sounded like a higher-quality recording. For me, music’s all about the emotional connection, and when your setup really clicks, whether it’s a proper hi-fi or headphones, you just want to listen more, rediscover forgotten albums, and actually play them all the way through. That’s exactly what happened when I improved the source. The Hexa and Aria are amazing for the money — they easily hold their own against the IE600s. I’m sure I’ll try some higher-end IEMs at some point, but honestly, I’m happy where I’m at right now.

Interestingly, I also have a pair of IE600 and a couple of days ago I was using a beanie over them(it was quite chilly outside). Sound got altered quite drastically and for the worst. It's probably because the ports were covered. Using the hood from my jacket instead was the better choice as that's not a snug fit.

Yeah me too, I have some very expensive sets, like the IE600, and I prefer the EW300 over the IE600... I still prefer my Ziigaat Odyssey, or my Mangird Xenns Top, but damn the Simgot is indeed very very good for the asked price

That’s sadly a common issue for the IE600 because of condensed water in the shell. If you put them in a small box with a bunch of silica gel packs, they should become normal again.

You certainly can! I love those and got them for cheap last Sennheiser sale.
