Long time since I posted here, but I have to comment on the Earbell E100. I own earbuds such as Sennheiser MX980 and Blox TM7 together with vintage earbuds such as Sony MDR E484 and Aiwa HP-D9.
Overall, I would put the Sennheisers and Blox at the top of my list. They are very similar and don't really lack anything. Fully textured bass, highs that are detailed without being piercing, wide and deep soundstage with a 3D feel...
The Sony E484 have got the best bass I've ever heard in a pair of earbuds. However, after a driver on one of my two pairs died, I was forced to start using my NIB backup pair and now I'm afraid to bring them outside. The Aiwas have the best soundstage I've heard in a pair of earbuds/headphones. I haven't heard the more expensive over ear headphones (except ATH A2000X), but these D9's are just incredible. It's like being inside of a huge dome where every instrument is clear and can be exactly positioned. However, bass is not very good on these Aiwas. I feel the same about them as the vintage Sony earbuds and don't bring them outside.
Cheap Chinese earbuds are like a godsend. I have enjoyed the Dasetn earbuds and looked up many other ones that have been introduced in this and other earbud threads on Head fi.
Overall, Earbell E100 is my budget favorite by far, when it comes to the sound. It is a bit thin sounding overall and it might not agree with some sources (for instance, I discovered yesterday that my otherwise good sounding Samsung YH-J70 HDD MP3 player doesn't work with the E100, but really well with my Blox BE3).
I have owned Sennheiser MX760 and sold them. I did not like the "sterile" sound combined with an unnatural soundstage. I still have my pair of AKG K319. I still like their dry sound even if they completely lack that 3D aspect of the soundstage.
The cheap Earbell E100 blow both the MX760 and AKG K319 away. They are not as good as the MX980 and TM7, and while the E100 might not be as good as the Sony E484 and Aiwa D9, they have a more balanced sound overall.
My only complaint is the fit...
