Paul has spent the past eight years testing and writing about gadgets and technology for the likes of Louder, T3 and TechRadar. I assume they’re capable of connecting to more than one device over the life of the headphones but the manual appears to indicate that there is no way to pair once it’s not the first time powering them up.

It’d take pretty fancy equipment to measure how much, but I’d suggest a good ten or fifteen decibels. Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. The US company claims that you'll get up to 12 hours' use with Bluetooth and ANC activated, and that extends to 22 hours with those functions switched off. Almost every headphone we test is checked by us: In addition to determining the frequency response, the heart of our measurements, we also evaluate the effects of noise that penetrates from the outside to the inside. This is slightly smaller than the default 40mm size that seems to feature in a huge swathe of headphones at the moment but anyone fearing that there will be a lack of bass extension probably ought not to be concerned.Pour ceux qui arriveront malheureusement que maintenant, voici une solution pour accoupler À NOUVEAU son casque. Who said you need to spend a fortune to get a pair of headphones that boast great sound quality, active noise cancelling and a long-lasting battery? For starters, JBL haven’t to my knowledge made a bass light product in their history (having rather too much bass on the other hand is something that has afflicted quite a few of their offerings).

COMBINING BLUETOOTH AND active noise cancelling in a headphone is a highly desirable option for that discrete ‘shut out the world’ ability that those on the move demand.

Battery life is great, noise cancellation is amazing and it comes with an aux cord incase you need a wired connection for any reason which is handy. The left earpiece has a micro-USB port for charging on its top edge (a cable is included in the box). The first and most important of these is that despite the potentially implied threat of there being vast, uncontrollable slabs of bass, the reality is more benign.

The specs for this JBL reveal a standard frequency range and a low nominal impedance – just what I would expect from an on-ear wireless headphone. Frustratingly, you can’t listen and charge the battery at the same time as the USB charging socket is inaccessible while the headphone is in use. With a 12 hour life, this isn’t too pressing but it means that a long fight will leave you dependent on a wired connection when you get off the plane.

There is plenty of bass extension on show and this is coupled with a decent sense of timing and drive. To their credit, the JBLs do a good job of cutting through the hustle and bustle of a busy bus or a crowded train compartment.

Or if you prefer, you can simply connect the JBL up as a wired headphone via the supplied cable with its 3.Testing itself was largely undertaken with a Sony Xperia XA1 Android smartphone via both wired and wireless connection although an iPad Air was also used for iOS testing.
