How do these fare vs. the NAD Viso HP70???
I understand that the latter are actually a bit worse than the old wired NAD Viso HP-50.
Does the same hold for the M4U8 vs. the old wired M4U1 and M4U2???
OferDon’t know but I own the 2 of the M4u1’s and one of the M4u2’s.
I like PSB a lot they are my travel to Europe headphones.
Gonna look around and prolly jump on this.
I just like the sound Signature.
OferIt’s kind of ironic since I jumped on the N70. That sound signature reminded me a lot of the N50. Though I must admit it’s been a while since I heard the N50.
OferI did enjoy the N70. The ANC is good enough, but definitely not modern. Micro phonics does become a small issue. The sound signature is one of my favorites though.
I can’t compare to the PSB, however.
OferThe M4U8 is tuned more toward clarity and detailed in the highs than the HP70, which is darker and muddier. This is sort of similar to the tuning of the M4U1 vs the HP50 (never heard the M4U2 but I assume it was very similar to the M4U1), although the HP50s were just darker than the M4U1s, not muddy sounding like the HP70.
I would definitely take the M4U8 over the HP70, but neither the M4U8 or the HP70 is the equal of their hardwired predecessors in terms of either frequency response or detail retrieval, they're less neutral and less resolving (possibly due to the bluetooth hardware).
The M4U8 does greatly improve on build quality vs the old PSB headphones, which were very prone to cracking.
If you need bluetooth headphones with mediocre noise-cancelling, these aren't bad. In terms of sound quality they outdo the offerings from Sony or Bose, but the noise-cancelling is far inferior. If you're willing to risk the poor build quality you're probably better off with M4U2s wired for pure sound quality (with even more mediocre noise-cancelling though).
