The Z7M2's bass sounds more upfront/visceral/immediate compared to the Z1R (the Z1R's bass sounds a bit far back, perhaps due to the vastly wider soundstage); the bass slam is more palpable. I consider the 1AM2 as the Z7M2's baby brother (I also have the 1AM2); if the Z7M2 feels as if you are surrounded by a wall of bass, the 1AM2 scales back the experience by two or three steps (but still carries that bass weight nevertheless).
Thx for the comparisons! I was thinking about buying an 1AM2 since it gets very positive reviews everywhere and there are some good deal for the equivalent of ~150 USD now, but the Z7M2 with those 70mm drivers are so tempting, its a hard decision, unfortunately I have no chance to compare them...
For a long time I thought I'm a bass-head, but after auditioning the 1AM2, I'm not 100% sure anymore.
Its hard to describe. I definitely need an emphasized bass (the signature of some brands sounds awfully thin and boring to me, esp. with 60/70s Rock with lacking bass impact, thus need some boost).
I miss not necessarily the the 'eardrum-hitting' type of bass, but rather the 'visceral' kind of sub-bass you almost feel within your body, around 50-80hz and below with a good extension and rumble. My theory is that I cannot tolerate sub-bass roll-off (unfortunately most headphones suffer from this), when mid-bass overshadows the sub-bass and/or bleeds to the mids.
These are the headphones/IEMs I had recent experience with, for reference:
- 1AM2: auditioned it in a noisy store with an iPad, but even with this non-ideal setup I immediately liked the smooth and fun signature a lot!
- XB950BT: meh, lots off mid-bass bloat, bleeding into the mids
- Sennheiser IE8: lots of mid-bass, overshadowing the sub-bass
- XB90EX: my IEM, I love it, but I treat them like babies now, since it is not manufactured anymore and the unused ones are sold on eBay for 500+ USD lol... If I ever find an over-ear equivalent of it, that could be my endgame
My 'gear':
- DAC/AMP: Fiio E10 (at the moment)
- Sources: Spotify Premium mostly, Soundcloud/Mixcloud sometimes. No Hi-Res sources.
- Music styles: Deep/Soulful/Funky/Jazzy/House/Acid Jazz/Rock/Fusion. As background music during work in the office. Mostly non-vocal focused songs. No classical.
Normally one would think that a 70mm driver is a guarantee for awesome rumbling subwoofer-like bass compared to the 40mm ones, but interestingly, based on the reviews so far, on average, the 1AM2 seems to get more praise for its bass (at least in its category), and the Z7M2 seems more controversial and even bass-shy for some. (all expensive headphones seem to be somewhat controversial though)
What do you think, would the Z7M2 be an overkill for streaming audio, and possibly sound 'less fun' than the 1AM2 if it reveals the weaknesses of the recordings and/or sources?
Or in other words: is the Z7M2 tuned for a more 'audiophile' signature (more analytical, and more mid/treble focus) and possibly the 1AM2 has a more forgiving, 'consumer'-friendly sound and maybe a better choice for non-perfect sources/recordings or certain music styles?
