The MiX-PD from BASN Audio is a cabled earphone that pairs a planar driver with a conventional dynamic driver in each earpiece, a mix reflected in the letters PD in its name. BASN offers it for stage use by musicians as well as for portable listening, and it is priced at USD 79.99. Buyers can choose between silver, black, grey, blue and green versions.
Key specs that matter
A hybrid layout places one planar driver and one dynamic driver in every earpiece. BASN gives a frequency range of 20 Hz to 40 kHz, a sensitivity of 106 dB and an impedance of 31 ohm. Cables connect through 0.78 mm two-pin sockets, and the standard lead is terminated with a 3.5 mm plug. The shell is closed, so noise isolation comes from the seal of the ear tip in the canal.
Engineering and use context
The two drivers share the frequency band - the dynamic unit is assigned the lower frequencies, while the planar driver covers the midrange and treble. Elsewhere in the catalogue BASN uses a planar magnetic driver on its own, as in the ASONE with a 14.2 mm unit, so the MiX-PD is the variant that adds a dynamic woofer to the planar design. The housing is built from clear, environmentally friendly resin topped by a low-profile faceplate CNC-machined from aluminium, which keeps the earpiece flat against the ear. The supplied cable is silver-plated copper, described by BASN as light and comfortable for stage and portable use, and it has an aluminium Y-splitter where the two ear leads join. The two-pin connection is detachable, so a worn cable can be swapped rather than the whole earphone replaced. Supplied accessories include silicone and memory foam ear tips, three pairs of each covering small to large ears, a zipper carrying case, a cable clip, a 6.3 mm plug adapter and a cleaning tool.
Pairing
Thanks to its efficiency, the MiX-PD can be driven directly by a smartphone with a headphone socket, a USB-C dongle DAC, a notebook computer or a pocket player. Through the supplied adapter it connects to headphone amplifiers, audio interfaces, stage mixers and in-ear monitor belt packs. Many aftermarket cables use the same two-pin standard, including balanced versions with 2.5 mm or 4.4 mm plugs for players that offer those outputs.
Alternatives
The BASN MTPro uses one 14.5 mm planar magnetic driver per side in place of the planar and dynamic hybrid layout.
