ME? Do you mean M2? I would say M4 is more similar to M3. M4 sounds slightly more accurate, but to me also somehow slightly more flat and boring than M3.

I have the Momentum 2,3 and 4. Soundwise the M3 wins against the M4 for me. The sound from the M3 is more involving and Sennheiser-like and you can hear it louder, but technically the M4 is of course superior.

IE900 + Sony NW-WM1Z Love that combo, especially the bass is fantastic, but I have also slight problems with the fit of the tips. Would love to have tips of size between M and S.

Yes, use a Camera Connection Cit and the WM1 cable. You also may connect iPhone X with WM1 without any cables via Bluetooth.

USB DAC and BT Receiver works fine with iPhoneX here, but I also had one crash so far (reboot of 1Z). I don‘t know exactly when, but it was when using USB DAC or BT Receiver.

I‘m happy now after firmware 3.0

Not a whole new sound. IE800 is a little bit more tuned for fun and produces a few more wow effects. IE800S has the more balanced, reference sound, may in direct comparison with IE800 be perceived dull, I don’t know. I like both. While the S is my favorite of the two, the sound tuning of the...

Andromeda on 1Z is nothing special. First Andromeda isn‘t known to scale very well and second it likes more OI to sound the most balanced.

I‘m also done, since I have decided that 1Z+IE800S is a portable dream team.

If there was a change in sound, and yes I also hear a tiny difference between 1.2 and 2.0, I think that change was not intended by Sony.

Is this the best IEM ever and therefore nothing left to say? :nerd:

For sure one of the best Ambient albums ever produced.

IE800S is one of the least physically invasive highend IEMs I know. You might have luck with those. Soundstage from HD800/S is of course better, but the bass from IE800/S is much better I think.

I own HD800, HD800S, IE800, IE800S and I also think the old HD800 is driven as good as the newer HD800S from my WM1Z (or WM1A). The HD800S is the more balanced sounding one though. Besides I think IE800S tops both. WM1Z + IE800S is my favourite Sony/Sennheiser combo.

I own IE800, IE800S, Andro and Vega. My personal ranking would be 1/ IE800S 2/ IE800, Andro 3/ Vega All of them are good enough for me to keep and use them. Vega is the most problematic one for me in a general sense, fit and soundwise. On the other hand Vega can be very fun to listen to...

Two Monoblocks. :muscle: ;)

I know that. I had asked nothing, just told that I love streaming and therefore wish that USB-DAC function will come with the FW update. No advice needed ... ;) I‘m in the same ball park, about 1 TB.

Two 1Zs, yeah I love them. I have a big local music library that fits in two 1Zs, but I would like to get rid of it and be able to somehow use Spotify with my WM1 players.

But I already own 1 x 1A and 2 x 1Z :confused:

Output impedance: „WM1Z and the WM1A are 0.94 ohms and 0.92 ohms respectively“ https://pmrreviews.com/?p=1193

I‘m a streaming guy. It is too time-consuming for me to handle a big local music library whose content often changes. Streaming is so much easier. I use Spotify only. Can‘t detect any differences compared to 16/44.1. Therefore I really would appreciate USB-DAC functionality.

For about that price I bought my second 1Z from Amazon. Had to wait a few month though. The „USA model“ does reference to the country setting of the firmware, not to country of manufacture.

This one sounds so f... good :)
