Clear sound quality with outstanding on-ear comfort

These headphones are perfect for those that like to listen for hours as well as minutes. The sculpted ear cushions provided outstanding fit and comfort no matter the age, or head size! My three year old was able to wear these headphones on the smallest size whilst I was also able to use them. Perfect for the whole family! The JBL dynamic audio experience is certainly present in these on-ear headphones and this is especially clear when utilising the aux cable provided as standard which requires no battery whatsoever. The built in mic with echo cancellation makes these headphones perfect for skype / video calling even in the nosiest of scenarios. Having recently worn these headphones on a busy train journey it was truly amazing how much I was able to shut off the rest of what was going on around me to focus on what I needed to get done. The bluetooth can be a little 'laggy' although having read other reviews this is fixable by downloading a firmware update... although this is only available on windows machines! Being able to control third party services with the wireless controls is a major benefit for if you're listening to your phone in your pocket and want to increase / decrease the volume or pause the sound all together. Unfortunately I wasn't able to utilise the JBL 'ShareMe' function.

Pros: Good build quality, Value for money Cons: Complicated

Review of JBL Everest 300 Headphones

Firstly I'd like to say I like these headphones a lot. Over the years I have owned at least 30-40 pairs of headphones including wired, wireless, in-ear & over-ear and these are by far the most comfortable. I usually get an aching after wearing headphones for a long time and I haven't had this at all with the JBL Everest 300 headphones. So if comfort is an important aspect of buying headphones for you then look no further! Audio wise they are impeccable, I've listed to a range of music, TV, Films and even games with these and they all sound fantastic. One thing to note is that when I first used them (via Bluetooth) with my phone there was a very noticeable lag. However if you download the new firmware from the JBL website on your PC and update the headphones then this is instantly fixed. It's very easy to do and only took me 3 or 4 minutes. The headphones generally feel like good quality. They are a good weight; not too heavy or too light and the fact they can be folded too is very handy indeed! The battery life is amazing! I've used them for hours and hours between charges which is a huge selling point for me, Plus even if you get caught short and they do run out of power at the wrong time then all you have to do is plug in the supplied 3.5mm cable and continue listening as no power is needed when the cable is used! There is a multi function button for answering calls and skipping tracks, 2 presses and the next track is played, 3 presses and the previous track is played. This functions perfectly well and is very easy to use. The noise cancellation is superb, even without any music they cut out a lot of the ambient background noise. With music on you feel totally immersed and the sound is astonishing. Overall I would highly recommend these headphones They have extra little features I like such as the 'left and right' labels clearly inside the cushions and a voice notification when you turn them on and off. The only little thing I would mention is that they are a little slippery so if you want to use them for exercising then that might be an issue, however this could just be personal to me.

Pros: Ease to use, Good build quality, Value for money
