Q: Questiondoes it come with a carrying case

Asked 1 year ago by ear.

• A:Answer No! I was surprised that at this price point it comes with a bag I wouldn't keep my sunglasses in. Almost every other comparable set of headphones on the market come with a case. I love the headphones but JBL needs to do better. You can buy a $30 set on Amazon that comes with a case. Some of them are really nice cases. Very disappointing.

Asked 1 year ago by Early.

• A:Answer Thank you for your question. Our JBL Live 770NC headphones come with JBL's Signature Sound for delivering strong and clear audio with a notable bass performance. While it didn't come with a dedicated "bass booster" feature as a specific hardware button or switch, you may customize the EQ settings via the JBL Headphones App. Through the app, you can adjust the equalizer to enhance the bass frequencies, effectively creating your own "bass boost" setting.
