What customers say about "Key Specs"

Nad Viso HP70 Headphones

I LOVE these headphones. The sound is a tad bright, but incredibly clear.
The best words I can use for the sound of these is "pleasant" and "deep".
To be clear, female vocals sound great - but the males are on another level.
The sound quality on Bluetooth is why I purchased the NAD-VISO HP70 The sound is sweet, full, and accurate.
The response is complete and even from the lowest instruments, to the highest vocals.

PSB Speakers M4U 8 Wireless Active Noise Cancelling HD Bluetooth Headphones

Very dynamic sound, with plenty of bass slam but never bloated or overpowering.
The sound quality is very impressive and really on another level from the other headphones.
Very good sound and Bluetooth functionality.
These PSB headphones are superior in sound.
The sound quality is outstanding. Balanced sound from lows to highs.

What customers say about "Size & Weight"

Nad Viso HP70 Headphones

The ear pads are small so they squeeze your ears.
The clamping force of the small ear cups allows these headphones to stay snug with the headband barely resting on my head.
Size of headphones prevents any pressure build up on the top of the head from the headband. I like it.
The bass is just where I want it to be. Perfect for my ears.
The clamping pressure is too high so the force on your already compressed ears becomes painful after time. Bad size for my head.

PSB Speakers M4U 8 Wireless Active Noise Cancelling HD Bluetooth Headphones

My hat size is 7 3/4 so not overly large, but not small either. Perfect headphones size for me.
The design is quite accommodating of my head and ears.
I'm the type of person who will use these for multiple hours a day and it was quite there for me. Good size.
The first week of owning these, my ears started to hurt, too large.
On my larger than average sized head I had to max out the extensions and still get some pressure on the crown of my head from the headband.

What customers say about "Features"

Nad Viso HP70 Headphones

When in ANC mode you can press the volume button to enable the Active Monitor feature, i like this feature.
The battery life is terrific and the controls on the back of the right ear cup are easy to utilize.
Noise canceling works great. I haven't tried it on a plane yet, but even in office it works wonders to drown out noises of AC.
When playing lossless wireleslly, i really can't tell difference between that and wired.
It comes with a nice soft leather case. Like this.

PSB Speakers M4U 8 Wireless Active Noise Cancelling HD Bluetooth Headphones

ANC is very good, specifically I've noticed many ANC headphones get a fuzzy background noise when active and these do not.
Bluetooth functionality is very good. Connects immediately, signal has no problems reaching anywhere in my house or work office.
Excellent sound quality, especially in On/Active and ANC modes using either the wired connection or over Bluetooth.
These are active noise cancelling headphones, and they do it well.
These are usable for up to 15 hours between charges, these should get you across an ocean without needing a charge.
