Antihippy has posted a review of the Aurisonics Harmony. It is a dual BA with one dynamic configuration. Priced at around $400.
Pros: Great high and low extension, natural sounding mids, bass impact, soundstage and imaging
Cons: Minor driver flex (improved with use/tips), finicky fit, tip/insertion dependant
For a similar configuration you may want to investigate the Easy LZ A2. It has the same configuration and I can attest that it is a very nice IEM. Also, it is currently selling on Amazon for for $115. HisoundFi has a review of the A2 on Head-Fi.
