The headphone volume seems able to overpower their own drivers and sound stressed out, with some distortion becoming apparent. 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. Let’s be clear, the JVC HA-S35BT Bluetooth headphones are a good value for the 50 bucks more or less you’ll pay. They have a closed ear cup design which helps block ambient noise without an active noise cancelling feature.

While off, a 1-second press will turn the headphones on, and a 3-second press will turn the headphones off. SOUND and FEATURES: The JVCs have quick and easy Bluetooth connection and are as wireless as over-the-ear headphones can get.luckily I have many other pairs of head phones, these are going back to the bottom of the drawer, little used, and forgotten.

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. However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs.

I suppose that's okay as we found the battery easily lasted all the way through an 11 hour road trip with our kids; but just be aware that you can't juice your headphones passively from a regular headphone jack when the battery dies.

Therefore, it's good to always have a full charge before use, as you won't have that to fall back on.On the lower end of the three buttons is the power button with an easy to feel raised “dash” in the center.

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. Personally, I found highs and female vocals to be clear without being overly harsh or sibilant; bass was admittedly a bit thin in the "regular" setting, but activating Bass Boost thankfully didn't turn things into a muddy, sloggy mess.Although these are over-the-head headphones that are normally characterized by their bulky nature, this model can be folded into a more compact form. There's not much to the product to garner the cost, when there are so many better and cheaper headphone options available on the market. I've been using it at work for several days and the battery indicator on the phone still shows around 80% on the headphones. The JVC HA-S31BT Wireless Bluetooth On-Ear Headphones offer 17-hours of wireless listening, and bass boost for high clarity and deep bass sound. I found the button locations a little difficult to use in the brief time I’ve been using this product.
