Set of 3 pairs of wired in-ear headphones. They contain a high-end dynamic driver to achieve great acoustic details. Each pair is specifically optimised for individual frequency bands. Black headphones let the bass stand out, turquoise highlights the mids and highs, and a transparent pair of headphones offers a balanced interplay of all frequencies. The headphones have a sensitivity of 112 dB, an impedance of 34 Ohm and are supplied with a highly durable replaceable cable with a 3.5 mm jack connector. On the cable there is a controller with an integrated microphone and controls for receiving calls or switching tracks. The package includes extensions that ensure that the headphones fit comfortably in each ear, block out the surrounding environment and do not fall out.
