Rated 5 out of 5 by from Work great I have had these for about a month now. They connect easily to Bluetooth devices. The sound quality is excellent. The talk thru and ambient aware modes are a nice feature especially if you wear them at work. The ambient aware modes does not amplify sounds like the Everest 750s do. The sound is more like normal hearing level. I used these on both Alexa and Google assistant. Activating the feature can be a little difficult but after I used them a few times I got the hang of it. Holding my hand on the earcup seemed to work best. Overall these are a nice headphone for the price. The Google and Alexa feature gives you a nice handsfree feature when you're busy.

Rated 4 out of 5 by from Almost 5 Stars... It's great device for it's purpose. The sound quality is excellent, the build is quality, the technology is brilliant, battery life is great, and the design is beautiful. However, when I wear it for long hours my ears begin to hurt. There is this intense pain I feel on my ears whenever I use it for long (last from hours to days) - and as a music lover this has happened to me numerous times. It get really uncomfortable. I hope the designers pay attention to the in subsequent models. Also my volume key got jammed/stuck barely two months after purchase so maybe that too should be checked. I still praise the sound quality!

Rated 5 out of 5 by from Great sounding, lightweight & sturdy headphones Loved these headphones straight out of the box! Not only did they come charged so I could use them straight away but they were the easiest to setup that I have ever experienced! The sound is crystal clear, and they pack a good bass. As soon as I put them on I was impressed. They fit firmly, but comfortably. (My previous on ear headphones were too loose and even came off during workouts). The fabric on the headband is super soft (and looks great too!) The padding over the ears is just right - soft but durable too. These headphones not only look good but are packed with features that I'd expect only from more expensive models - Amazon Alexa and Google Assist - to be exact.

Rated 5 out of 5 by from A lot for the money! I recently bought the JBL Live 400BT Refurbished on JBL's website instead of new, and I'm very glad I did. For $55 bucks it's a really good deal, with impressive sound quality. It also has a few features such as "Ambient Aware" which I didn't know it came with, but are very useful. The shipping gave me many shipping updates and showed where the package was, and it shipped fast. I was impressed with JBL's shipping system. It's a very good set of headphones, with a lot of value for the money, particularly if you buy it refurbished like I did. I couldn't even tell it was refurbished or anything.

Rated 5 out of 5 by from Great product, hearing aid compatible I have struggled all my life with my hearing and wear hearing aids in both ears. This makes it impossible to use buds. Other wired headphones are ok but the sound is not very loud and the cable snaps so easy. So when I found these they are excellent. Connected to my Samsung Mobile A71 no problem. They sit on the ear which means the hearing aid does not feed back. Sound is so loud that I can use them without aids in at all. With aids in I have to actually turn them down. The box is good quality and the headset itself feel good quality. My only gripe is that they are a bit tight, would be nice to have some flexibility in how much they press on the ears. Well done JBL and with a 30 day no quibble return policy. What's not to like.

Product Q&A

Are these noise cancelling?

Asked by: jomama567
Hello, I think the previous answer may be a bit misleading, as these DO have a noise cancellation feature. I have these headphones (JBL 400BT) and they DO have a noise cancelling - there are two different "background noise" / "white noise" sound settings (one sounds a bit like ocean waves, the other like static). The button to control this is on the front right headphone ear, at the front. Works relatively well (But not as well as true noise cancelling).

My headphones power themselves back on after turning them off.  I have tried the recommended resets but it does not fix this problem. They only stay off while being charged.  Please help!

Asked by: Dreeds
I have the same problem. Used with Blue Tooth. The headphones only stay off when charging. I have looked at the instruction sheet but have found nothing about it. Factory reset didn't correct it.

Does the cord have a mic? And if my daughter connects the Aux cord to her chromebook will she be able to speak? (she can't connect to her school laptop with bluetooth, so I want to make sure if she plugs these in she will be able to hear and speak)?

Asked by: middleschoolmom
The microphone is built-in on the earcups of our JBL Live 400BT. It will work both on Bluetooth and via wired mode.

I have been using these headphones for a while and I really like them, but after wearing them for a while they start bothering me. I feel like they put pressure on my head/ears. Is there a way to get it loose?
