It features a built-in 610 mAh rechargeable battery, which provides up to 12 hours of listening time with noise-cancellation switched on, and up to 22 hours without. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.

When not in use, the headphones have a flat-folding hinge, giving them a small form factor when in storage.

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. If you switch off Bluetooth and switch on noise cancellation – the typical airplane scenario – you get 30 hours.In an environment like an office or public space, there is enough of a noise ‘cut’ to ensure that your listening experience is enhanced. Depending on the quality of the mic, without any risk of it touching the clothes, the TUNE 600 BTNC's integral one may offer more distinct audio than on-the-cable microphones. On an airplane, you can use the cable and active noise cancellation, but you’ll have to bring your own two-prong adaptor (they’re available at most airports for five or six dollars).

This means you shouldn’t have any problems creating a decent seal and making the most of the JBL’s noise-cancelling ability. Gabriel’s vocals are clear and well handled, sitting at the front of the mix without being separated from it. It’d take pretty fancy equipment to measure how much, but I’d suggest a good ten or fifteen decibels. Starting off with the design, and the JBL Tune600BTNC has a fairly basic approach to headphones, offering a supra-aural (on-ear) style of headphones that offers a fairly tight fit from its plastic band, with a pleather set of ear cushions to keep your ears comfy while you jam.

The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid.Charging time for these headphones is very quick, also the battery life is even longer if you decide to use the jack to jack cable that comes with them, with the noise cancelling function still in use. These headphones are predominantly used when on public transport, and with the noise cancelling function, these are ideal as everyday rouged headphones, and with the long 20 hour battery life when using Bluetooth, you can go a long time without worrying about having to charge them. And thanks to the additional detachable cable, music can be enjoyed endlessly in wired mode, with or without Active NoiseCancelling.

Your ears are usually bumpier than your head around the outside of your ears, so it’s harder to get a seal. Shedding the connection cable at the very least is something that is pleasingly liberating and in conditions like poolside at a hotel, you are unlikely to care unduly about any notional drop in quality.
