Frequently asked questions about this product
What battery life does this Harmony ANC offer?
Up to 50 hours of listening per charge, enough to last the day — and well beyond — without going back to the charger. The wireless connection also reaches up to 20 metres from the source.
Do these headphones actively cancel ambient noise?
Yes, they feature active noise cancellation. It adds to the passive isolation of the over-ear cushions, which enclose the ear before the electronics even come into play.
How far can you move away from the source?
Up to 20 metres, which exceeds the range of ordinary Bluetooth. You can leave your phone in one room and move around the next without the sound dropping out.
Can you answer a call without taking out your phone?
Yes: a built-in mic handles hands-free calls, and the headphones are compatible with voice assistants: Google and Siri, triggered from the ear cup.
Do these headphones fold for carrying?
Yes, they are foldable and described as easy to carry: once folded, they slip into a bag without taking up the space of rigid headphones.
Are these headphones made from recycled materials?
Yes, they are stated to be made from recycled materials — a constant across the Energy Sistem range, which applies the same approach to all its headphones.
Are the Energy Sistem Harmony ANC headphones new and under warranty?
Yes, new and genuine, with a 1-year warranty provided by the invoice. Keep it: it is all you need for any workshop repair.
Sixteen hours of playback per charge, and a folding design that makes it fit in a bag. Made from 100% recycled GRS-certified plastic, for 167 g on the head.
Thirty-five hours in total with the case with noise cancelling off, and 20 h with it on. Silicone wingtips hold the earbud without pressing, from the sofa to a run, and an ambient sound mode keeps you in touch.
•35 h in total with the case without noise cancelling, 20 h with it
Up to 35 h of conversation and 30 m of range. Three microphones isolate your voice from office noise, the oval memory foam cushions filter out what surrounds you, and the busy indicator stays visible from every angle.
More than 100 hours of wireless battery life, and recharging that does without a cable: just set it on a base. Foldable for long journeys, with an M button to customise from the app.
Plugged in over USB-C, it carries the sound as well as recharging. Up to 75 hours of listening without noise cancellation, 45 hours with, and the app offers 8 equalisers and 3 isolation modes.
Three microphones per ear and wind-cutting processing keep the voice intelligible mid-run. Up to 12 h of listening from the earbuds with noise cancelling off, and 48 h in total with the case.
The JBL Headphones app tunes the equaliser to your taste, and Voice Aware lets you hear your own voice during a call. Connected to two devices at once, 220 g on the head, 76 hours of stated listening.
Two battery regimes: 10 h from the earbuds alone and 40 h in total with the case, noise cancelling on; 12 h and 48 h with it off. Ambient Aware and TalkThru let outside sounds back in.
The silicone ear hook with memory wire bends to any ear shape and stays put during exercise. 10.5 g per earbud, touch controls and Ambient Aware mode to stay aware of the road.
