I came across some info regarding this IEM last week, the
RSS Roland's RH-PM5. This is Roland first and only IEM, designed to be used on-stage for monitoring purpose. You are probably thinking what I am thinking: Yes, this baby looks too gorgeous for stage-only usage. Unfortunately, this is kind of a difficult-to-get IEM. There ain't many places that carry this in store as Roland is marketing it toward pro-audio use. Plus the MSRP of around US$280 isn't really cheap for a single balanced armature IEM.
Spec:
Transducer: balanced armature
Sensitivity: 104db @ 1mW
Frequency Response: 20 Hz – 16,000 Hz
Inpedance: 32ohm
Connector: 1/8″ (3.5mm) gold plated
Cable: 2.2m OFC wires
Denon annouced a new top-end IEM for their current line-up, the AH-C710. It looks much more ergonomically desiged than their current top-end, the AH-C751. There really isn't much information about this new IEM beside these: it has a 11.5mm dynamic transducer and a new 'optimized' housing. MSRP is expected to be US$230.
[UPDATE]
SoundMAGIC, one of my favorite budget IEM maker, is releasing its very first balanced armature based IEM into the market, debuted as PL-50. Hopefully I might get a pair to review soon. I am not sure about its MSRP at the moment, but Hong Kong dealer is selling it at around $70.
Spec:
Transducer: 6.5mm balanced armature
Sensitivity: 109 +/- 2 db @ 1mW
Frequency Response: 15 Hz – 22,000 Hz
Inpedance: 55ohm +/- 15%
Connector: 3.5mm gold plated
Cable length: 1.2m
