Description

The P903 is a wired in-ear headphone from Nagaoka's pastel colour series. Each of the six versions combines several pastel shades in one design. Inside each earpiece is a 9 mm driver with a neodymium magnet, which the maker links to higher-resolution sound output.

For fit, the set comes with ear pads in S, M and L sizes plus a slow-recovery foam ear tip in size M. The cable is 120 cm long. The earphones have a 16 Ω impedance and 100 dB sensitivity, and cover a 20–20,000 Hz frequency range.

The set connects by cable. The maker lists a six-month warranty, an open-price listing and a launch date of 25 September 2017. The model is now marked as discontinued. The colours are Pink, Blue, Purple Blue, Yellow Green, Purple Pink and Red White, each with its own model number and JAN code.
