Does a decent job but it didn’t fit me well
It’s a good product - looks good and produces good audio for calls and music. My ears hurt because of the sharpness of the product - so I had to return it unfortunately.

Ich nutze diese Kopfhörer vorwiegend für mein Steam Deck und Meta Quest 3. Da Bluetooth Kopfhörer hier eine ziemliche Verzögerung haben, ist AUX immer noch das Beste. Ich nutzte vorher JBL On-Ear Kopfhörer, auch für ca.20€, die qualitativ zwar völlig in Ordnung sind, aber leider stören diese auch das VR Erlebnis weil sie mir der Brille kollidieren. Dann habe ich gute alte iPhone Kopfhörer per AUX verwendet, die haben die besseren Höhen als diese hier, aber fallen mir immer raus, das Hartplastik hält eben nicht gut. Und genau da setzen die Sennheiser an. Sie bieten erstens 4 verschiedene Größen der Stöpsel, mir hat die Standard-Variante die verbaut war schon sehr gut gepasst. Dazu dichten sie die Aussengeräusche sehr gut ab, wenn man die richtige Größe gewählt hat. Wie ein Ohropax eben. Der abgewinkelte Stecker ist auch sehr sinnvoll, gerade bei der VR-Brille. Gerade Stecker brechen gerne schnell ab, wenn mal was runter fällt. Der Beutel zum Aufbewahren ist auch super praktisch. Das fehlt bei vielen anderen Herstellern, und dann findet man die anderen Stöpsel nie mehr. Sound-technisch gefallen sie mir außerordentlich gut. Die Höhen sind zwar etwas flach, aber die Mitten und Bässe klingen sehr schön. Ich kann für den Preis von ca. 22€ also absolut nicht meckern.

Excellent quality and product. It comes with a nice little pouch to carry it in. Good noise cancellation as well.

3.5mm jack wired headphones with Mic for mobile phones is more and more disappearing from the face of the globe and personally I do not like this idea at all, including that I do not want to even buy any mobile phone without 3.5mm jack option. Sennheiser CX300S are not very expensive headphones but there are still a quality headphones from this firm, and I buy there headphone products for two decades already, like this one Sennheiser CX300S mainstream headphones, to those Sennheiser headphones of much higher quality and much more expensive. I even bought this same Sennheiser CX300S headphone model one time in my life already, and I did not make mistake, because it is a good product. Yes, you cannot expect the "Start Trek" sound from them and for High Fidelity listeners, but they are not created for them in the first place, and for the others this headphones will be just fine, especially in this price ratio. All in all, I recommend them. Thank you.
