"The Exotic"

MSRP: $300
Fostex’s TM2 is an interesting product as it is not uncommon to see audiophiles purchasing one simply for the MMCX Bluetooth module itself. To which I ask: why not just get a TRN BT20S?
Overall, the TM2 is certainly a decently good sounding dynamic IEM in its own right, but the high price tag is still a tough pill to swallow. The midrange is clean and free from any bass bleed, though the biggest problem I have with it is the upper midrange and treble peaks that makes things a little too shouty and sharp for my sensitive ears.
I know I’ve told you all that I’ll only focus on sound quality in this list, but this is an important point: the charging case does not contain a battery for on-the-road charging. You still get roughly 10 hours of use off of a single charge, but that’s still a pretty big dealbreaker for many people looking for a TWS set.
