Wired in-ear earphones
Sennheiser's IE audiophile earphones between the IE 300 and IE 900, with 3D-printed zirconium shells and a neutral tuning. Reviewers found them detailed, with tight, controlled bass.
-
Amorphous zirconium shells
The shells are 3D-printed from amorphous zirconium, rated three times as hard and bend-resistant as high-performance steel, with a scratch- and corrosion-resistant finish.
-
Neutral sound
Reviewers found the tuning neutral and detailed, with deep but controlled bass and clear treble that avoids harshness.
-
Balanced cable included
A 3.5 mm cable and a 4.4 mm balanced cable are both included. They are reinforced with para-aramid fibre and attach with MMCX connectors recessed into the shells.
