What do you mean with "a little lower"?
Very cool, very very nice, you have three of the more important BT Headphones.
There is NO WAY that I am gonna let you come out of this with just two lines. Man, we all count on you.
Read my first post at the beginning of the thread to have an idea of a comparison methodology (it is mine, you can develope yours, but, it is a start).
And do something more in-depth if you can. Adding the HK too.
WHich goes deeper in the bass? Which one has got more rumble (this vibration on very low notes)? Which one more punch?
Which one has got warmer mids?
Which one more clear and precise highs, not sibilant?
Which is more balanced and neutral out of the box, and which one boost some frequencies (bass, low mids -muddy-, mids, highs)? Which can be better retuned with an EQ (some headphones sound better out of the box but show to be very limited if you boost something with an EQ).
Which has got better connectivity? Better range?
Better detail? Soundstage?
Let us know, I am ******* jealous!!!
Where do you possibly read that? THis is exactly the opposite of what I read. At least if you talk of the hiss of the ANC. People stated that, for example, the BeoPlay H8 filter more noise but adds hiss, while the M2 filter a bit less, but adds no hiss.
Now, if you talk of the normal hiss of the BT Amp, I did nt read anything about it.
Giogio, don't beat me up!!
I clarified going, that I am a novice, and don't have golden ears. Also, my priorities differ from a lot of head-fiers..
Bluetooth is my #1 priority.
My novice status doesn't allow me to hit those little picky points you mention. All I can do is give a general consensus of the 3..
As it stands now after 2 or 3 days of listening to all 3, the Senn M2 comes out on top. IMO, the M2 clearly out distances the other two in all areas..Not by leaps and bounds, but better.
Also, my M2 most likely is a later model. As Amazon was out of stock at one time. So, it could be some fixes were in place.
With the Senn M2s, I have experience NO CONNECTION PROBLEMS. I have experience no HISS. The Senn M2 blocks out more noise than my MK2s, which are not NC, and better than the Def Tech..
The Senn M2s, give up nice clear highs, lows. M2's bass is more of a bass than on the Def Techs. Not into hitting any or using EQs.. I am using Poweramp off my Note 4, playing mostly flac files.. With my Mk2 I have to turn on aptx, with volume up + power button. On the Senn M2 and Def Tech the aptx comes on automatically.
I didn't add the HK BT into the mix, because my Sony 1RBT Mk2 clearly out distances the Harman Kardon BT... The Harman Kardon BT is my gym/workout headphone because of its superior clamping force.
In summary, to me, the Senn M2 is the clear winner. Whether I will keep it is still up in the air. The M2s, although they don't clamp as tight as the HK BTs, they are still better than the Mk2s. I could work with the M2s in the gym. The cups on the M2s are the smallest too. Almost feel like on ear phones, but they are comfortable. Just for the record, will take the M2s to the gym with me again.
