Ryanjsoo has posted a review of the six BA driver AF1120 IEM over on Head-Fi. From the review it sounds like these are great IEMs for the money. Read the extensive review by clicking the link below.
Pros – Stunningly balanced, Exceptionally linear bass and midrange, Very detailed, Great soundstage depth and imaging, Perfect comfort
Cons – May be a bit neutral and polite for some, Thin, tangle-prone cable, Loose, keyed MMCX connectors, Sub-bass extension isn’t as exceptional as the rest of the sound
