Not on AE but on ebay you can find the kube V1 and V2 which are bassy earbuds with good sub bass extension for the form factor.Bit on the Snow-Lotus 1.0+ CE from Amazon and received today. First impressions are that these are quite close to my MX365s in signature; perhaps a bit cleaner and/or brighter, but hard to say yet.
I saw the SLs repeatedly mentioned for their efficiency/volume on mobile devices, but they seem to be almost exactly on par with the 365s in that respect, too. Overall, SL 1.0+ seems like a solid MX365 alternative (given the Senns are no longer for sale) for a similar price and with better build quality. Sadly though, the overall ergonomics don't tip in the SLs' favor, between the weight and bulky cable split. I also have to give the nod to the 365 shells for fit in my ears.
Since my main use for buds is on the go and driven by mobile devices' mediocre outputs, I may still go through with the AliExpress sampler just for fun. So far, between the H180/Datura/SL1.0+, I've yet to find one that quite outdoes the 365 when summed over SQ+volume+ergonomics. The SL is damn close, though.
Any recs for a super bass-heavy option under $8-10 on AE? I recall using some Sony buds sometime around 2001-05 that were far more impressive on the low end than the Senns or anything else I've tried so far. Would be fun to have a pair like that lying around, even if it's not my usual preference.
Or on AE othere's the vido earbud for $3 which is one of the bassiest earbuds. Apperantly the red version has slightly cleaner mids but that could just be unit variance
