SE425

If you go the IEM (in ear monitor route) and don't do the full custom molds, then Comply foam tips are a game changer for isolation at a much more budget friendly cost. I bought Shure SE425 over a decade ago and still use them to this day.

I second these as a long time professional live/broadcast sound engineer and life long percussionist. My Shure SE425s split after a decade of sweating with them in. Someone along the way recommended the KZ ZSN Pros as a cheap but great throw away pair of IEMs. Ive had them for years now and they just keep sounding better and better as they break in. Its takes a little time for the high end to mellow out but I’ve never felt the need to have my SE425s repaired because these sound plenty decent enough. You absolutely have to get the foam isolation tips though if you wanna use them while playing drums.

May want to find a way to increase your budget for the ear buds. For what you have there, that may not cover dual driver buds for bass response and kick. When I switched to IEMs I bit it and borrowed money so I could get what the rest of the band got, Shure transmitter/pack system and the se425 dual driver buds. Even the se215 is a third of your stated budget. If you have anyone you know that would let you listen through or borrow what they are using, single or dual driver or both please do it. I was fortunate enough to borrow a triple driver set for a gig years ago and it was just pant shittingly good. but, out of my budget completely.

I have the Shure 425’s but they’re my only pair or iem’s based on recommendation (not counting AirPods) So I can’t really tell you anything on comparison. With the foam ear piece it blocks out a ton of ambient sound. I just generally prefer headphones for comfort so I usually only use the iem’s when I’m doing a lot of running around in noisier environments like trade shows or docs (where I need to monitor sound).

I'd try the cheaper Amazon ones (KZ ZS10 Pro for example). I use those regularly, but I've also used Shure 215 and 425. Frankly, I love the fit and feel of the Shures but don't love the sound. My KZ are WAY better than either, especially once I switched to foam tips on them. The Shure's just aren't worth the money.

Agree. I've used 215s, 425s, some UEs (don't remember the model) and currently use ZS10 Pros with foam tips. For what I do, the ZS10s are the best. The 215 and 425 are not worth the cost IMHO - they were the most comfortable to wear, but I only used them with the stock silicone dome tips and they never had enough lows nor enough isolation. The ZS10 were better sounding with stock tips, and then the foam just made them even better. You didn't say what you play. For reference, I drum at church, so it's acoustic drums playing rock style music but not super heavy, for a couple hours a week. If I was playing professionally or otherwise for significantly more time, I'd get customs that were more comfortable than the ZS10s.

I'm a drummer and have used the 215s (whole band had them to start with) and feel there was a world of difference switching to the 425s... Others in band (bass, electric, and acoustic /lead vocal) swear by the KZ ZS10 pros. At $45 on Amazon those they might be worth the shot just to test.

Significantly more clarity/articulation, and sound isolation... And yes, the result is less volume. I used to turn up trying thinking I needed more bass and click, but what I really needed was a tighter bass generally articulate sound with less bleed over from the acoustic kit. Oh one more thing... The foam tips are good, but you should change them out regularly. I'm noticing additional bleed as I smile or move my jaw around, with foams that are now 7 month old. Have read they should be changed 3 or 4 months, I believe it.

I did the same switch a while ago and can say I had the same experience. I was so used to the 215s that the more articulate highs of the the 425s irritated me at first. But in the end you just hear the band/backing track much clearer and can turn the volume a bit lower.
