AH-GC25NC headphones
I’d been looking for a decent pair of headphones for a while. I’m pleased to say my looking is over. The AH-GC25NC headphones offer great sound, capable of reproducing crystal clear highs and thumping low end. I used to used headphones at night, when all is quiet. That all changed with these. Their noise canceling design cuts outside noise dramatically! A worthwhile purchase!!

Over-the-ear headphones GC25NC
Well made, comfortable, and great sound.
Love the noise cancelling feature for when I take a nap.
I was pleasantly surprised with the quality vs the reasonable price paid.

DENON AH-GC25NC headphones are not top-rate
I am disappointed. DENON used to be a top-rate manufacturer, but no longer is. These phones are about half as efficient as the Sennheiser and Grado ones I already have. The cord is also shorter than the other phones and required that I buy a longer extension. The ear pieces are too small to enclose my ears, making them very uncomfortable.

"A Sonic Oasis"
My wife recently experienced these Denon headphones on a Turkish Airlines flight and she raved about them. She was delighted I remembered and even more delighted to receive them as a gift. The sound and look amazing. With 5 kids at home, she said their noise cancelling capabilities and amazing sound give her "a sonic oasis" when she needs it. Highly recommended.

Great sound, quality product, competitively priced
Quality, quality, quality product. Sounds great. Fits comfortably. Use these with my phone. A setting on my device was limiting the sound quality. Once I selected the right "live" sound mode on my Motorola g stylus 2021 the sound was amazing.

Paramount Over Ear Headphones
Exceptional quality, comfort and eye appeal. Noise canceling settings are very easy to use and the tap feature makes it very easy to carry on a conversation when needed.

Good value
Very nice sound, good for guys who don’t want Bluetooth, which doesn’t provide the necessary bandwidth for high fidelity tracks. The only weakness is that the differences among 3 noise canceling modes are hardly noticeable.

The headphones themselves are incredible in terms of both sound and build quality. The problem is that they're way, way too heavy. I had to take them off after ten minutes because they were giving me a headache and neck pain. I work in an open office and bought these for the (fantastic!) noise-cancelling, but I can't even make it through one call with these. My husband seems to like them but I've noticed he doesn't like to wear them for more than half an hour or so, I assume for the same reason.
