Great headphones. They sound great turned on AND off. I was worried they were going to be cruddy if the battery power ran out, but they sound good either way. These do require one AAA battery which is included. I hope they last a while.

outstanding and excellent product

My son needed headphones for his virtual learning. These sturdy headphones were a good choice. They were easy to put together and the sound from them is amazing. These headphones are good and were at a reasonable price.

Yes you can pay more...if you want wired headphones..these are perfect for the price

I just got this product and I really love it, it does what it's supposed to do

Picked them up this afternoon basically for travel and to replace a set of Parrot Zik headphone that while 8 times the price of the ZX110NC's (Bluetooth), fell apart in a couple of years of periodic use. Slipped these on, lightweight, comfortable, clicked on the power switch, and wow. Connected to home entertainment center, watching 'RattleSnake' on Netflix, good soundstage, voice track ever so present. Immediately happy with this purchase.

I had to get new headphones because my old one's that I had for about 10 years the wire broke off.So I purchased a new headphones to replace my old sony headphones.Boy what a difference in the sound!These noise canceling headphones are great.I only use them for watching TV at night so I do not need the battery that came with the headphones.Great product as always SONY!

I love these headphones. They provide great sound for a reasonable price.

I bought these about a month ago use them every day for an online course I'm doing they have good volume control drown out back ground noise well worth the money.

Very good sound..I couldn't believe how clear it was..plus blocking out all the outside noise!
