## 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
