Up to 65 hours of battery life and ANC that adapts to the surroundings

JBL promises up to 65 hours of listening, or 50 hours with noise cancellation enabled. If you use them for about three hours a day, they will last you over two weeks even with ANC on. And if you forget, a five-minute charge is enough for another four hours of music, according to the manufacturer.

Noise cancellation is adaptive: four microphones continuously listen to the surroundings, and the headphones adjust its intensity accordingly. The Smart Ambient mode works in the opposite direction, amplifying ambient sounds so you can hear announcements on the train or a colleague at your desk without taking off your headphones.

For working from home, connecting to two devices at once is useful – for example, to a laptop and a phone, so you won’t miss a call while watching a video. Additionally, the headphones automatically pause music when you take them off your head. In the JBL Headphones app, you can adjust the sound with an equalizer or have it tuned with a short Personi-Fi 2.0 listening test. An audio cable is also included in the package, so you can plug them into an airplane jack.

Customers praise sound and battery life, but some hear clicking

On Alza, the headphones have a rating of 4.5 out of 5 from 115 customers, 89% of whom recommend them, and over 2,000 units have been sold. Written reviews most frequently praise battery life, comfort, and sound with more pronounced bass, which can be toned down with the equalizer in the app.

Nejčastější výtka? Zhruba šest z 36 psaných recenzí zmiňuje cvakání nebo vrzání při pohybu, dva lidé pak upozorňují, že se zapnutým ANC ve větru sluchátka šumí. Pár recenzentů není spokojených s mikrofony při hovorech v hlučném prostředí nebo s dotykovou plochou, kterou lze omylem spustit. Na pocit z nošení má vliv i tvar hlavy – někomu sedí perfektně, jinému netěsní.

Not suitable for running or carrying in a backpack without a case

JBL Live 770NC are not sports headphones. One reviewer writes that they fall off her head during yoga when bending forward, another describes them as unsuitable for running – also due to the mentioned clicking and ear sweating. Anyone who wants to carry them in a backpack with keys and a laptop should be aware that the manufacturer only includes a fabric pouch, and a hard case must be purchased separately.

If you are looking for the best noise cancellation on the market, keep in mind that these are mid-range. One reviewer on Alza himself admits that they cannot compare with the ANC of the more expensive Sony WH-1000XM4.

Commuters and home office workers will be pleased

Anyone who sits on a train or bus every day, works from home with a laptop and phone, or simply doesn’t want to charge headphones every few days, will likely not go wrong with JBL Live 770NC. At 1 874 Kč with code 2026ALZAEXTRA25, they are also the cheapest on Alza in the last year. Athletes and those who make many calls outdoors in noisy streets, however, should look elsewhere.
