Very comfortable headphones. Bought for watching movies, no inconvenience for long listening. It holds a charge for a very long time, I forget the last time I charged it. The sound is not loud, but deep, the bass is excellent. The size is not for the street, although for someone on the contrary, a large size will be just right for a walk. An excellent choice for home use.

As I understand from the comments, many have faced a similar problem, so I definitely do not recommend it. The previous ones of a similar level from another manufacturer lasted longer and died from mechanical failure. In general, headphones for a year at the indicated cost - decide whether such a purchase is appropriate for you. Different pros: They sit comfortably, easily connect to sources, after almost a year of operation there are no mechanical problems, aesthetically they look like new…

I use it mostly at home for remote work. At home, the sound insulation is very good, sometimes you even have to move one ear a little, otherwise you can’t hear when they turn to you. They seem to be pressed against the ears quite well, but at the same time they do not hold on to the head very tightly. With strong inclinations, the headband slips. For me, this is not a minus, but just a feature.

On the one hand, they are relatively comfortable, you can work all day, and the charge will last for another day or two after that. On the other hand, there are cheaper headphones that hold a charge much longer, the quality of the product is very doubtful, they withstand the warranty year, and then fall apart. In fact, headphones for a year. Do you need them at this price - think for yourself.

Within a week of purchasing them I had several issues with these headphones, the JBL Live 660NC. The biggest issue I've had is an unusual crackling sound, which appears to be related to the noise-cancellation itself. This crackling noise is quite intrusive and cannot be easily ignored. The noise cancellation on these headphones isn't great either, in fact I'd say it's decent at best. The battery life is the standout feature of these headphones at 40 hours. In general, these headphones did not…

These headphones are very comfortable. There is sometimes a bit of clamping force, but most of the time the cups just fit snugly. as a braided 3.5mm audio cable for passive listening. The Live 660NC's noise cancellation is truly amazing. Quiet humming noises are reduced just as much as fan noise. I'm impressed with the noise cancellation on them. It's actually better than the ANC I've heard from other higher RRP headphones. The call quality is clearly audible to your group and they can hear…

Pairing was easy. The battery life is amazing. I'm really surprised at the rate of battery degradation and how long the amazing battery life lasts, but now it's a "charge and forget" mode. I'm not sure if the included audio cable will work with these phones when the battery is low or not, but if it does then no need to worry. Either way, you can charge them up pretty quickly; I wouldn't say anything other than charging my iPhone. Range is great too. You can leave the connected device and move…

I personally like the design of the 660NC headphones. They have a subtle low profile and sophisticated aesthetic. I appreciate the matte black finish that helps prevent smudges and fingerprints. The fabric-covered headband isn't as flexible as we'd like, but the ear cups rotate nicely. The plush memory foam ear pads are a snug fit and feel durable. They're not that heavy, but definitely built like a tank. It's also nice that JBL included a nice canvas carry case in the box. I was a bit…
