Review: クリアな高音で高コスパのイヤホン！ - この値段でコスパが非常に良い！！ WEB会議などで使用してもクリアに聞こえます。 マイク性能も不満などは全くありません ゲームで使用もしましたが、足音もよく聞こえて定位感もしっかりしているのですが高音域がクリア過ぎるからなのか、高音が響き過ぎる為なのか射撃音や爆発音などを長時間聴き続けると少し疲れます。 現在はWEB会議時、オーディオブックや動画などで気軽に使っていますが非常に使い心地も良いです！！ とにかくこの価格帯で何年も使えるマストバイなイヤホンが手に入る今の時代に感謝です！
Review: いい！けど高音が、、 - イヤホンの耳に付けるところの硬いところが、割と小さめだと思います。なのでつけててら全く痛くありません。また、マイクの性能がとても良いと思います。（通話で相手にこのイヤホンを使ってもらい、自分が聞いてみました。） しかし、ゲームで使ってみると、高音がシャリシャリと聞こえて少し高音が痛かったです。低音は痛くないです！

## 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
