Photographed (And FR Graphed): TRN-STM Earphone

The TRN-STM is a 1DD + 1BA earphone in the <$25 segment. It comes with three screw-on tuning filters (gold, red, blue) that appear to differ in length. At an impedance is 24 Ω and a sensitivity of 106 dB/mW, the TRN-STM is driven easily with any phone. My full review to follow.

Get the TRN-STM at Wooeasy Earphones Store.
