Note: Originally, I did buy these used to save a few bucks. After discovering a break, I ordered a new pair and had significantly better results. If you use EQ, these even rival the 200-dollar kinds. Sony ZX-110s are known to be used by casual listeners to enjoy the support of EQ software. I’ve even seen people wear them while doing live covers. When professionals wear something, it’s best to find out why and trust them on it. That’s why I took a gamble and bought these.[When I bought used]I really really really wanted to like these. The cups were comfier than the standard zx110s, but the audio didn’t come close to the standard. I compared the zx110nc to the standard zx110 I already owned and found it’s volume and sound to be significantly less. While this did improve when I flicked on the “noise cancelling” switch, I noticed vocals were clearer and the sound was louder. I live alone, noise canceling had nothing to do with this performance. I tried to test it out with the tv on but could still hear the television. It seems the noise canceling can at most damper the noise of an electric heater. Nothing higher. You’d have to turn up your volume to the high twenties and even thirties to block out a person’s conversation.For some reason, the pair I had had cracked speakers. Meaning the black plastic that covers the actual speaker was slightly cracked form a weak foundation. Not sure how this happened during manufacturing, most likely someone but manual blunt pressure and “popped” a crack into it.Sadly, the audio is great with the so-called “noise canceling” on, but not enough to support the idea of changing a battery every ten days if you listen for eight hours per day.I’ll maybe buy it again to see if I just had a lemon. But there’s a lot of reviews with the issues I had.I did buy new, and had a significant change of mind! I didn’t realize how much two little cracks on the earpad covers could change so much![Second Attempt, bought new]Upon arrival, I was greeted to the firmness of the pads that help with my stemming and adhd symptoms. The sound was a lot better but slightly airy. That’s when my mom pointed out, I needed to tighten the band. That’s when the real results came, and even the noise canceling was a success. I didn’t hear anything, not even the cars outside. I live near the airport, and I didn’t hear the planes or the helicopters helicopters. I even didn’t hear the TV that I forgot to turn off.If the sound is still not to your satisfaction. I highly HIGHLY suggest you use EQ. It’s FREE. Honestly, the headsets don’t even need them, just make sure the headband is NOT loose!

I started a new job that required trainings with over the year headphones. This pair was perfect for that. It synced with the computer and provided comfort.

Reasonably priced and very good quality.

Noise-cancelling at a reasonable rpice.

Good for listening to music and decent option when trying trying to portably making music. Folds up nice but insides get dirty and become hard to clean the battery for noise cancellation should’ve been a open and close panel not a remove and replace.
