Just so it's clear, I'm not in the camp that consider the B2 boring, heck they're quite "too fun" for me to actually truly enjoy them. The thinness kills engagement in the mids and will probably be suitable for EDM or synthetic music without real instruments that benefit from a more mature tuning like the S8. Although I can fully understand how they are boring to most people and consider them to be their borderline on how neutral they can get while to me it's the most fun I could tolerate. I actually tried several tips just to alleviate this issue, with the stock tips ithey're almost unbearable to me unless I'm in a noisy environment and the extra mid bass slam is welcome and bass quality isn't that cruicial. I appreciate their technical side tho, love the somewhat 3D imaging, instrument separation (although quite forced) and detail retrieval. It's just the tuning and bass quality that ruin the experience for me.
For the sample tracks of what I am talking about, my issue is actualy present with every music that has vocals and real instruments but here are some:
Why We Ever - Hayley Williams:
The bass in this track is quite upfront but will still be enjoyble with gears with a flatter (midbass) tuning and/or better bass quality than B2. With B2 the bass is almost one-notey and masking a lot of the other information in the mix especially in the mids and is actually quite tiring to listen to. With my other gears (ER2SE / ER4SR, S8, SSR, Illumination, etc.) it's actually a great track to listen to.
Take The Power Back - RATM
This is a great example of a track with good electric guitar tone. With the B2 the guitars are less engaging from the thinness issue I have. It has the illusion of a cleaner sound presentation because of this thinness at the expense of accurately reproducing the girth (if you will) of the instruments.
Bad Asteroid - The Aristocrats:
This track is another example of how B2 drowns you with (low resolution) bass putting guitars behind the mix, giving the user the illusion of a detailed, clean sound. In reality, it's lowkey v-shaped and if you care about the lost information, you'll definitely be underwhelmed by it.
I can list more tracks but I guess you'll get the idea when you compare them to more mature sounding IEMs. ER2SE/ER4SR are the extreme examples but even with just an SSR (w/ Xelastec tips) the tuning is way more mature than the B2 and will reproduce instruments more organicly.
