Light weight and comfortable with fantatstic sound quality, battery lasts a long time and with controls on the side easy to use they dont take long to charge and simple and easy to set up I use these in the gym and they work perfect no wires and dont.

In terms of headphone battery life as a significant factor in the purchase decision, it depends on what you want to use the headphones for and potentially how often you will be able to recharge them.This is the middle button, but I mentioned it last because you must learn the location, slightly above the easy to feel power button. Headphones with a higher impedance of around 250 Ohms and above are then more suitable for playback from really powerful signal sources or using a headphone amplifier, otherwise the sound coming out of them might not be loud enough. These JVCs were charged up and synced in no time, have great sound (I listen to metal with a lot of bass) and have never given me a problem. SOUND and FEATURES: The JVCs have quick and easy Bluetooth connection and are as wireless as over-the-ear headphones can get.

Today we are reviewing two cheap models made by JVC - the HA-S31M-A which is the wired version and the HA-S31BT which as the name suggests connects via Bluetooth. Bluetooth range was impressive--I actually managed to walk all the way upstairs and into the kitchen from my daughter's bathroom during a listening test and they still held their connection.I don't think they will be comfortable for that Also, with my Jabra ear buds there is a voice that tells you when they are turned off or on.

Max volume is far too loud for my comfort so if you have hearing loss or don’t value your hearing, they can be plenty loud. The maximum range represents the maximum distance from the audio transmission source that the headphones can be used for wireless audio transmission. However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs.The lower impedance will ensure that the required volume level is achieved with less power, thus extending the life of the player. Other than that complaint, I found that using the array of controls on the earphone edge was far easier than other headphones I’ve used. The JVC HA-S31BT are affordable on-ear wireless headphones that support both Google Assistant and Siri voice assistants. Towards the top of your right ear, near the headband, is the +/- volume rocker that doubles as the next and previous track buttons.
