Review: 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.
Review: Kopfhörer für Steam Deck und Meta Quest 3! - 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.

## Questions & Answers

**Q: Does it have a microphone and how good is it?**
A: Works well on my phone and PC for taking calls at least.

**Q: One customer claims it has volume control. Unless I'm missing something, it does not have remote volume control.**
A: It does not have volume control per se, but it can be configured.  There are +/- buttons on the part of the cord where the mike is.  The default on an iphone is those buttons skip the song forward and back.  In settings/control center, you can redefine these buttons to use as volume control.  I suspect that android operating systems have something similar.

**Q: Do these have same length left and right cables**
A: Yes. The cables are the same size.

**Q: Can I get an answer on exactly how long the cord is?**
A: 1.2 meters that's from sennheisers website
