The Panasonic RP-HJE125 in black are wired in-ear headphones designed for a comfortable and secure fit. Their ErgoFit shape helps isolate outside noise, allowing you to focus on your music while the 10mm dynamic drivers deliver a balance of rich bass and clear treble. These headphones feature a 3.5mm mini-jack and a 1.1-meter cord, providing enough length for easy movement. With a frequency response of 10Hz to 24kHz and an impedance of 16Ω, they are well-suited for daily use with smartphones or portable players.
