I was already impressed by the first momentum, because I thought: Finally my headphones because!
Small, compact, very good sound (Lossless files are paying off!), Very good design, robust, on the go and trtz Over-Ear.
Perfect, he still was not however. Especially since it made for some difficulties to use it as over-ear (not with me I've little ears).
What bothered me was the pressure for about 2 hours I felt due to the high contact pressure. I thought that's the concept due to better insulation to ensure. But think:
The M2 (Wireless) makes it better. None Hotspot more after prolonged wearing on the go. The comfort is increased which is also due to the larger ears. I have a feeling that they are also the reason why the stage is greater in these than in the first generation.
The new folding mechanism is a nice to have, so I get him finally into the small backpack bag, in which I got the M1 nich, super!
The noise-canceling can be switched on even in the cable mode, Wen's interested, I'm excited but it is generally not because it (subjectively) for me is relatively little effect. The best sound insulation is still guaranteed by the construction.
At the ear you will find the buttons for navigating, some with double function.
After Eingewöhnphase you meet each key without any problems.
When they had at least one cable can settle with remote control, the supplied has not rendered and must (if wanted) are expensive bought later by Sennheiser. I recommend that from the on-ear version, since this does not have this flaking paint (like my M1).
Now comes the (sound):
Unfortunately not as hoped, but the best for a Bluetooth handset, you can get. What can I say, very similar to the M1 but not this (strong) Valley to the heights around. In Cable mode, unfortunately, he does not sound like the wired M2 (other drivers?) Which m. Mn sounds better than the M1. Eben bigger stage clearer highs, more subtle centers. The Wireless loses but surprisingly little sound when one sets out the cable. Well just the best Wireles handset currently on the go
Note also still applies that the impedance in the wireless mode is 480 ohms and not 25 ohms ~. This you have to turn up the stronger source possibly something stronger.
So if you want the best sound is examined from the M2 cable.
Who wants to have the most practical clearly the M2 Wireless.
Who is wise buys the M1, possibly also needed.
But what bothers me is that there is no induction charger for the handset. That would have the whole package rounded (in terms of practical).
Because of this and because of the price (450) I can not recommend anyone this. Dear wait one probably comes ne version 3 in 2 years, then anything can (hfftl.).
Please feel free to evaluate, thank you!
