With up to 24 hours of battery life, you can listen to your favorite audio all day with the blue LIVE 400BT Wireless On-Ear Headphones from JBL. Your favorite music is streamed via Bluetooth wireless technology through 40mm drivers that deliver JBL's Signature Sound. Thanks to multi-point technology, you can pair the 400BT on-ear headphones with up to two devices, such as a smartphone, tablet, or laptop. With the press of a button on the earcup controls, you can easily switch between the two.

The on-ear headphones also feature a built-in microphone, letting you make hands-free calls via your smartphone, or interact with your mobile device's various digital assistant software programs, such as Google Assistant & Alexa. Use them to send texts, make calls, answer questions, and more; all while your mobile device is safely and conveniently tucked away. Speaking of convenience, the LIVE 400BT headphones features a swivel and fold-flat design that helps to make them more portable and easier to take with you.

Multi-Point Connection

This technology lets you pair the LIVE 400BT headphones with two Bluetooth-compatible devices, so you can quickly and easily switch between the two. No more re-pairing or needing a separate set of headphones for the second device. For example, while watching a video on your tablet, you can switch to your phone to answer an incoming call, or while playing a mobile game on your phone, you can easily switch to a video conference call on your laptop.

Ambient Aware & TalkThru

The LIVE 400BT wireless headphones make for an ideal solution to your on-the-go audio needs, but when walking around outside, it's important to be aware of your surroundings. With the touch of a button you can activate Ambient Aware, which lets more outside noise in so you can hear things like announcements more clearly. With TalkThru mode activated, the music volume is dropped, so you can have a quick conversation with others around you, without taking off your headphones.

Comfortable Design

With all-day battery life, JBL has fitted the LIVE 400BT headphones with a fabric headband and soft ear cushions, which are designed to help make them comfortable to wear for extended periods.

Go Wired When You Need To

If the 400BT's battery is running low, you can connect the detachable cable to use them as a traditional set of wired headphones. The cable features an in-line microphone and remote, so you retain the ability to control your audio, make hands-free calls, and interact with your digital assistant.

Can you listen to two sources at once (example a phone via Bluetooth and a ps4 through 3.5mm connector)?

Asked by: Dibbs
Our Live 400BT has multi-point technology, you can pair the headphones with up to two devices, such as a smartphone, tablet, or laptop, and easily switch between the two when you want but you can only use one source at a time. Bluetooth and aux cannot be used at the same time. To learn more about the Live 400BT kindly visit : https://bit.ly/34gfE2m

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
Hey, just wanted to ask if the mic does work without bluetooth on and connect with the aux as i was planning to use for my pc also

Do these come charged and ready to use out of the box or will they need to be fully charged before initial use? 

Asked by: Adh74
The initial charge varies but you can just charge it for 2 hours to make it full and play music with it.

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.

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).

Can these be connected with the computer with a USB to use during video conferencing? Thanks

Asked by: ques
The USB port on our JBL Live 400BT is only meant for charging. If you prefer to use the headphones via a wired connection on the PC, you may need a PC audio splitter in combination with the aux cable to make it work on the PC.

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?

Asked by: Arianin
The headband on our headphones can be adjusted/extended depending on your preference.
