Once powered up, a single short press of the button gives you a tone in the headset for Bass Setting 1 ("regular"--I guess), another press gets you two tones for the Bass Settings 2 ("boost" mode. Compared to other Headphones the JVC HA-S31BT is awarded an overall alaScore™ of 85/100 = Very good quality.

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. They listen to nine recordings for each pair of headphones, which cover a wide range of music and radio genres, giving a rating per recording and an overall verdict (not an average). Select “JVC HA-S35BT” from the device list and the indicator will slowly flash blue when the connection is complete.

Guess I should sell em online to someone who thinks jvc makes the best of everything like I used to think. Get a comprehensive look at your chosen headphones and see if these are the ones that will best suit your needs. I won't take too much of your time, but here's a link to my full online review if you're interested.

However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs. They're incredibly comfortable; responsive, easy and intuitive to use; and actually provide great sound quality for music and movies served up for those on the go. They'll go loud if that's what you want, but these aren't necessarily geared for bass-heads even though a central feature of their marketing identity is the Bass Boost capability. Sound wise these are excellent the bass boost really does sound awesome with gaming drum and bass games, they have a good battery life and decent enough Bluetooth range for what i need i use these mostly to connect primarily to my pc and they have no issues connecting or with any of my other Bluetooth device's.Although I sounded a bit muffled to myself, she thought I sounded like a very clear land line connection. The compact design does not compromise on sound quality and with smartphones voice assistant compatibility, integrated mic and remote, your flexible friend for hands free operation.

This is the middle button, but I mentioned it last because you must learn the location, slightly above the easy to feel power button. In fact, you might be hard-pressed to notice much of a difference between the regular and Bass Boost mode playback--my daughter actually couldn't tell them apart. there is an ever so slight crackle when you have your phone volume maxed and the headphones themselves turned up but easily fixed by popping it down one on your phone.

One particular point of note that earns these cans a gold-star for usability (at least in my book) is the thoughtfully designed control cluster. Up to 17 hours of wireless listening is available from the large capacity integrated rechargeable battery.
