Pros: Lightweight-Incredibly comfortable to wear, I forget I have them on. Battery life-SUPER long, I've not measured the 70 hours battery claim, but they lasted two international flights with multiple layovers and zero charging interruptions. I've been super pleased.

Excellent, well-balanced sound at a reasonable price. And the headphones exude solidity. In short, very good JBL. It's reassuring to know that you can have really good equipment without breaking the bank.

These headphones are good quality. They sound amazing. I have small ears/head and these fit nicely. The only thing I don’t love is the ambient aware setting. I thought this would be great for the office, but it picks up on small sounds (typing, machine noises, etc) that are really distracting.

The Tune 670NC Headphones fit well and are flexible & durable, with the lows and mids sounding very good. Noise cancellation is superb, and microphone is good for voice calls. There headphones will also last a while as I had no issues getting through a whole day using these headphones with their...

Bought these for my husband who's now retired and wants to watch nothing but politics and war shows all day long, sending me into a depressive mood. I figured that if he didn't like them I could connect them for myself to use to listen to my music while doing my housework, achieving the same effect.

I have never used headphones for anything other than work and these exceeded my expectations. I first became familiar with the buttons which seem to be very simple to use with not alot of options. I first tested out the overall sound listening to music and was amazed by how crisp the sound was.

I am a fan of the JBL LIVE 670s, and these are a nice "little brother" set of headphones which are staying in my collection. I have recently developed an appreciation for on-ear headphones (as distinct from over-ears), and these are comfortable, serviceable, and sound surprisingly good.

I'm truly loving these headphones after listening to them. These are a compact style of headphones, and fold up nice to fit in a purse or backpack. I also found out that you a variety sound options with the JBL app. The sound from the Tune 670NC headphones is very good for being compact.

I like that they are so light. I like that the bass is firm and solid and does not get in the way of the upper frequencies. The "sound stage" is very, very good. I do not like that the adjustment sliders are too short. I have a typical round/oval head and have them fully extended.

I have owned a number of JBL headphones and have noticed improvement's each generation, especially with setup and the App. This was the easiest setup yet, I turned on the headphones and instantly a popup on my phones asked to pair. I opened the JBL Headphone App and there they were.
