I find that part of horny!

What I do not like the EP-650:
==========================
- The joints that connect the bracket element with the two ear cups are processed extremely inexpensive and bend with me, like a broken elbow, even to the outside, even though they are not sure. Let's see how long does that.
- There is no power supply there.
- If the microphone is used, the headset in the Bluetooth headset profile are connected and therefore have only one abnormal poor sound. Then not suitable for music.

What I like the EP-650
=====================
- The many connection options:
* Via Bluetooth speakers in profile with a high data rate (A2DP)
* Via Bluetooth to control a music source (AVRCP)
* Via Bluetooth the headset (hands-free) mode (HFP)
* Per 3.5 mm jack as a headphone
* Per USB as a USB sound card with headphone and microphone
- TRS and USB cables are included
- The ear capsules encapsulate a bit the surroundings, not as good as in-ear, but twice as comfortable
- The ear cups can be rotated to its suspension, it is possible to bow to ~ 10 ° so forward or push back (not meant: laterally folded away, as with DJ headphones)
- It has a few Kontrollknöppe ane the page
- An LED ring displays bicolor the operating and charge status
- The part looks quite chic

Neutral I would specify that the volume changes are not passed to the source device via buttons on the right ear part, but only the internal setting is changed. This is not to be included in the assessment. So down to the downer that only a Bleutooth profile is simultaneously possible, I think that the part of his money is absolutely worth it. I have not tried the way the NFC feature.
