JBL LIVE 400BT headphones review: Light weight and soundtastic

JBL LIVE 400BT headphones come with Ambient awareness feature that allows you to listen to your favourite tracks while you hear ambient sounds too

When we got the JBL LIVE 400BT on-ear wireless headphones, at first glance these headphones looked simple and sleek. We noticed that the company has labeled the left and right insides of the earpiece, so users would know which side to put on which ear. The JBL LIVE 400BT on-ear headphones look pretty decent with mesh design and it appears cool, young and stylish. So, like always we took the new gadget that has come to us for a review out for a spin. This is our review of the JBL LIVE 400BT headphones.


Before we talk more about the design let us tell you about what you get inside the box of the JBL LIVE 400BT on-ear headphones. These come with a micro USB charging cable and a 3.5 mm auxiliary cable that is 4 ft (1.3 meters) in length. A mic and a remote come fitted with the Auxiliary cable. So, if the headphones run out of battery they can be wired into your smartphone for uninterrupted playback. Apart from that, you can also find an instruction manual inside the box. That is helpful when you first try to connect the headphones with your device, the instructions are pretty simple to follow.

Comfort is the most important thing after sound quality whenever we buy headphones. The padding on the JBL LIVE 400BT is decent. So before even listening to music, we tried to assess the comfort. Before putting on the headphones we were worried about if they might not fit our head, but the headphones fitted pretty well because of the padding and the expandable headband (which by-the-way has metal extenders).

The on-ear headphones covered our entire ears but if you have a larger head your ears might peep out of the ear cups. But, JBL is marketing it at over the ears headphones, not on-ear, so this could be the case with some. The padding is soft but after 30 minutes of continuous use, they become a little tight.  Soft PU leather material has been used to make the ear cushions. This does not make the ears feel sweaty and does not fall off while working out or jogging.

The left ear cup sports a Micro USB charging port for charging the earphones. It takes around two hours to get the headphones fully charged. Once juiced up the headphones can deliver up to 24 hours of playing time. On the right ear muffs, it sports a power switch that can be turned on by sliding it. The Blue flashing light indicates that the power is on. The left earcups also consist of a volume control button and a multi-function button to play/pause the music.


The headphones can be easily connected to your smartphone using Bluetooth. Over that, two devices can be connected simultaneously. The headphones can be paired with your Android device and a tablet or laptop at the same time with Bluetooth connectivity. Once paired the headphones do not require permission to connect again. It connects automatically every time it is turned on. To test the connectivity, we placed our smartphone in one room and then went to my balcony (about 30 feet away) to water the plants and we still had connectivity in the balcony. Amazingly, when we kept the headphones on the desk while working, we were able to still listen to the music that was playing. The audio drivers are very loud.

To test the sound quality, it is very important for us to listen to music that we are familiar with. Please Don’t laugh, so we tested the on-ear headphones sound quality by playing one of our favourite track by Charlie Puth “We don’t talk anymore”. It was easier for us to quickly pick out places where it sounds different, better or not so bright. However, the sound is quite good overall.

This feature helps you hear the sound of traffic or horns while you are crossing or walking on the road or traveling in a metro or a bus by lowering the volume of headphones.

The feature can be easily switched on or off by clicking a dedicated button on the right earmuff. As mentioned earlier the JBL headphones are equipped with passive noise cancellation feature that cancels most of the unnecessary sounds in the surroundings.
