Pros: Comfort and better than UE700, Economic choice
Cons: Cheap outlook or housing.
I compared this ultra sound TwinBA IEM with UE700.
UE700 and GH-ERC-DMS, both are dual/twin BA, but different tuned.
audio source : iPod touch 4G 32GB and iPhone4G 32GB w/ ALAC or MP3 320KBps , 93~94dB normalized.
Outlook and packaging:
outfit made with plastic and inner is seems to urethane.
cable is really same as MEElec A151. ( shorter than A151, but same shape, material, connector )
S,M,L - Shure like silicon tips and carrying case. an adapter. it's all.
a license paper included.
It ... was impressed.
Bass is better than UE700. mid to high freq seems to same like UE700.
Specially high freq. hears crispy and sharp. really clear.
It's similar like T-PEOS H-100 on high freq. (bass is better than H-100)
There's nothing to explained how to fit on my ear. (even L,R not printed !)
But we know this type of IEM how to wear.
Wear cable to around earflap, insert silicon tip into carnal side.
It is really comfort to me.
I don't care MSD whatever, payed totally around 80USD in Amazon Jp. (inc. delivery cost)
Economic choice !
