Worth the money!

As runner I was looking for a decent in ear hedphone, with good water resistant, who can fit properly during my jogging activity but also usable for remote working calls. Well after some weeks I can definitely say this is a best buy for the purpose. This product is extremely light when dressed, materials are good and solid, the touch controls are extremely satisfying to use in every condition. Compare with my airpods 2nd generation I can say they are best in sound quality, fit, battery duration, touch controls. If I need to find a cons, well I can consider the max volume a little bit under-performing especially with transparency mode on and some amplification of wind noise during sport activity which can be correct turning on noice ANC feature. Highly recommended!

CX True wireless wie erwartet

Sound Qualität ist meine Meinung Top wie alle die andere Sennheiser Kopfhörer
Die Touch Funktion ist praktisch
Die Verbindung schnell und einfach
Trag Komfort kann nach Ohrmuschel große varieren

Hohe Tonqualität, aber leider nicht für jeden Typ von Ohrmuschel tragekonform

Die CX Plus True Wireless sind ihr Geld wert. Der abgegebene Sound ist klar und nicht übertrieben basslastig. Auch die Batterieleistung ist wie beworben. Nur leider hatte ich nach wenigen Tagen Nutzung Schmerzen an meiner Ohrmuschel, was daran liegt das die kantige Form nicht zu meiner "engen" Ohrmuschel passt. Eine Rücksendung des Artikels ist aber problemlos möglich gewesen. Hier kann man also nichts falsch machen.
