Der rundum Gute. Bügelkopfhörer in Kompaktbauweise, wie aus einem Guss. Rundum gut, solide verarbeitet, preisgünstig, ohne billig zu wirken. Klingt relativ hell. Klappbar, aber etwas sperrig. Lässt sich auch über Sennheiser-App bedienen. Tastenmarkierung in Blindenschrift.

Der kleine Bruder des HD 4.50BTNC (siehe Platz 5) hat kein Noise-Cancelling, klingt aber ähnlich solide: Flauschig mit sauberen Bässen und feiner Stimmwiedergabe spielt er sich durch die Playlist. Einziges Manko: Der Taster für die Regelung der Lautstärke ist ziemlich schwer zu treffen. Die Akkulaufzeit von über 35 Stunden ist aber spitze.
