For the past 50 years I have considered myself an audiophile. When 'stereo' first came out in the early fifties I was fascinated and 'hooked'. Over time I find out how to build the latest, greatest stereo record players for family and friends using the best quality parts available at the time. Vivid music reproduction and two-channel sound separation over multiple speakers was my passion.
So, needlessly to say, over the past 50 years I have spent a small fortune on sound equipment and engineering. Fortunately today, modern music enthusiasts have so many fantastic and versatile choices to select from. Since the early sixties I have used over-the-ear-headphones to thoroughly enjoy crisp, clear, harmonic stereo sound playing all kinds of music entertainment genres. Over-the-ear-headphones are still my personal means of enjoying the exhilaration and sheer pleasure of music without disturbing anyone else.
So, when I had an opportunity to evaluate a complimentary set of JBL Everest 710 Over-The-Ear Wireless Headphones, I was excited. They are not only Bluetooth, but accept audio outside sources through a 3.5mm jack, can be 'paired' for shared audio with other brands of headphones using ShareMe 2.0 technology, and allow me to receive calls while I am wearing them. Big Plus! But, most important to me is that I can now listen to my entire 'retro' vinyl collection using the 3.5mm cable to my amp and equalizer since my record player is already connected to my amplifier. WooHoo!
After enjoying these JBL 710 Headphones for almost two weeks. I am convinced they are the most versatile headphones for their quality and price available. They are lightweight at nine ounces, yet ruggedly built, featuring a softly padded, adjustable head band, which is very comfortable to wear. The headphones fit so well over the contour of my ears, I find them actually soothing while enjoying my music for several hours at a time. In fact I have dozed-off wearing them twice this past week alone. The earphones swivel inwardly approximately ninety degrees, which allows for optimized, over-the-ear fit, and easy packing into the included hard case.
These headphones are the passive, sound isolating, kind. They are not active, electronic noise canceling. Because noise canceling utilizes 'electronic clutter noises' to block out ambient sounds I prefer the more passive sound isolation technology for clearer and crisper sounds as long as my ear pads fit well. The JBL Everest 710 Headphones are an excellent passive fit. Because the inner earphone pads are made of soft, synthetic leather material they conform well to the shape of my ears. They may not be what you should wear in 'wet' environments like in heavy workouts, or, weather outside. They can only be replaced by a JBL Service Technician. Additionally, cleaning the pads with clear water only, and, or, diluted, very mild soap seems like the only viable choices. The JBL folks wanted us to protect these headphones for storage and travel so they included a hard-backed carrying case in the box.
Now for the 'Nitty-Gritty', sound quality. This is the area for which the JBL Everest 710 Headphones excel. First, they feature 40mm dynamic drivers, actually like tiny speakers in the headphone, which have larger diaphragms for more powerful bass delivery. The audible pitch of the sound is from low,10Hz, to high, 22,000Hz. The limits of our hearing range is 20Hz to 20,000Hz. So, this JBL 710 is at lower,10Hz, and higher, 22,000Hz for greater resolution sound for impact. The sound loudness, or sensitivity level is at 96db maximum – a lot of volume. Overall, the JBL engineers did a super-job of creating a mid-range unit that delivers crystal clear treble highs and balanced, rich lows that do not punish your ears. They play like ear candy – crisp and sweet listening enjoyment. Background nuance sounds like falling rain, far away thunder, or the distant chirping of birds is reproduced so you hear it as three dimensional, moving from ear to ear and as if it was in motion moving about your ear from top to bottom. Wow! I can't get enough of this dynamic studio quality sound reproduction.
It is funny, but realistic too. Younger folks who have listened to music on my JBL 710 claim the bass isn't loud enough. I think they have been indoctrinated into heavy, reverberating bass kind of music genres. They don't appreciate, nor hear the subtle background refinement of less prevalent, complicated, dynamics. If you prefer loud, pulsating, ear-ringing bass, these headphones may not be for you.
JBL utilizes the latest version of Bluetooth, V4.1, which delivers great sound quality. Pairing my devices (phone & other headphone unit) with the JBL 710 was extremely simple. But, Bluetooth is Bluetooth and still a 'work-in-progress'. I use Bluetooth for these headphones about eighty per cent of the time. And the ShareMe 2.0 technology is a plus, plus for connecting two sets of headphones. However, I have noticed a slight degradation in the sound quality when two headphones are connected. But, I am an old-fashioned audiophile, who loves the wired connections for reliability and non-interference. When I connected the 3.5mm cable to my amp to play my vinyl records – it was unbelievable. In fairness my record player is not Bluetooth capable so I really had no way to compare wired and wireless. But, the orchestra sounds and music was 'live' and had more depth then just over my living room speakers. Thank You, JBL. Be aware when you plug-in the 3.5mm jack to an another audio source that your internal battery power of your headphones is disconnected automatically, and the auxiliary audio device then controls the sound volume.
Other Features – The JBL Everest 710 includes a hard-backed carrying case; a USB charging cable; a four foot long 3.5mm wired cable with jacks; a Quick Start Guide; a Warning Card; a Warranty Card, which encourages you to register this product for 'updates' and establish the purchasing date for your one year warranty period. It only takes two hours to charge the battery using the included USB charging cable, which gives you up to twenty-five hours of use. Wow! The 'controls' are all on the bottom of the 'R', right hand ear pad and include a sliding, 'ON', 'OFF' switch; a (+) speaker and (–) speaker volume switches; a combination play / pause, receive call and stop call switch; Bluetooth pairing switch; and the ShareMe 2.0 technology pairing device switch. Audible features talk to you as you are using the controls.
A word about the controls. After two weeks of groping for the controls I now let my fingers to the 'walking'. It is only a short learning curve to get a 'feel' for the controls on the right ear pad. The more you use these headphones the quicker you learn the controls.
I highly recommend these JBL Everest 710 Over-The-Ear Headphones. I love them and use them daily. The only kind of 'workout' activity I take them on is my early morning walk. They are studio quality and not really built for heavy perspiration-kind of workouts. JBL has packed a lot of quality, high-end sound in these headphones and versatile features. And, twenty-five hours of battery life on a two hour charge? For yourself, family member, or friend, this makes a great gift, which will be appreciated for many years.
