OK I must be crazy, right? I just got the Sennheiser IE 900 since the vast majority of reviews say it’s like the IE 300 (which I love the fit in particular), but next next next level.

So I thought great, upgrade to the 900 and sell the 300… but no matter what I do, I feel like the 300 has significantly more bass and power versus the 900. I thought perhaps my fit is just way off? But I tried with the same tips as the 300 to ensure I’m comparing apples to apples and still felt like the 900 was just… weaker? Significantly less bass? Didn’t really feel like I was getting anything more at all. Not even remotely worth 4x the cost over the 300.

So did I do something wrong or anyone else have the same experience?

Bonus question: I recently sold my Shure SE 846 to get the IE 900 since so many reviewers say the 846 is dated and not great any more… but I have to say the Shure had a MUCH better bass presence without being overpowering. I just could never get the SE 846 to feel comfortable… so anyone else struggle with the comfort and find a way to make it work? Are there magical tips I should try that would do it? (I tried Spinfit W1 and Westone Stars, both eventually were uncomfortable in mainly my right ear after some time).

Also note I’m a drummer so I do prefer a stronger bass presence. Thanks in advance for your thoughts here…
