Go wireless with these value-packed Bluetooth headphones
When I recently got my first pair of Bluetooth headphones, I was surprised at how quickly they became useful in so many ways — from listening to music at the office, to making phone calls, to watching Netflix or YouTube clips on my tablet. These JBL headphones get you into Bluetooth wireless convenience at a reasonable price. And we've been really impressed lately with the sound performance of JBL's headphones in this price range. The Live 400BT uses large 40mm drivers for punchy sound with full bass.
Some cool extra convenience features
JBL added some nice touches to make these Bluetooth headphones extra-useful. Tap the left earcup to access the Google Assistant or Amazon Alexa through your smartphone, then just speak your commands. You'll set up the voice control assistant of your choice using the company's free My Headphone app. These headphones also come with an Ambient Aware mode, which uses the built-in mic to increase the volume of ambient sounds. That helps you stay aware of what's going on around you. There's also a handy TalkThru mode that reduces the volume of the music, so you can have conversations with others without having to take the headphones off.
