Mobile gadgets have firmly taken over our lives, with all the comfort and functionality they offer. Back home after a hard days work, we tend to plug our ears and listen to our choice of music, play a game or watch a movie on YouTube or any other website, by means of our mobile phone or a laptop. As technology is advancing, it has made this leisure activity even more comfortable, courtesy wireless headphones. You can place the wireless headphones on your head and walk over to the refrigerator easily to get a chocolate bar; you can go to the next room to see if the kids are really still asleep; or you can walk up to the window and see what is going on outside. Put simply, you can use them to enjoy your entertainment needs, without disturbing others.

Recently, I got the JBL E40BT headphones for a product review. Based on the premise that such devices increase our mobility and keep us from getting entangled in cords and cables, I decided to check out the new creation from JBL. Take my word, you have got to use this wireless innovation to appreciate the benefits it offers to us. According to me, the E40BT is the perfect complement to a mobile phone, tablet or a Bluetooth technology-equipped laptop computer. Read on to find out.

Out of the box, the E40BT comes across as a stylish, wireless headphone. Basically, this headphone keeps you connected, not tied down. Its Bluetooth technology allows wireless connectivity with your smart devices, with single-button access to JBL Pure Konnexx technology enabling a pure connection to your mobile phone for clear hands free calling. For the price conscious user, the E40BT carries a retail tag of R6,990.

On the outside, the E40BT is substantially plastic thats designed to resemble metal, although there is some real metal too. The hinges that connect the cups to the headband have metal caps, but the material around them is all plastic. Soft, leatherette ear cups cradle your ears for all-day comfort while providing a heightened level of passive noise reduction. Not only can the metal band be

adjusted to fit different size heads, but the cups can also rotate in and out to help achieve that perfect fit.

I found the headphones to be comfortable, fully covering my ears and doing a good job of passively sealing them against outside sound. Both the power button and charging port are located at the bottom of the left cup; JBL promises 18 hours of play time on a charge. The same port can also be used for a wired audio connection if you prefer, using an included cable. Technically speaking, the E40BT packs in 40 mm drivers, theres impedance of 32 ohms, sensitivity of 42dBV/Pa at 1kHz, while minimum frequency response measures 20 hz and maximum frequency response of 22 kHz respectively.

To test the E40BT, I plugged them first with my BlackBerry device. I played some songs stored on my phone, watched a couple of movies on YouTube and listened to Zubin Mehta and the Los Angeles Philharmonic Orchestraand was treated with equally impressive audio from these JBL headphones. They deliver pretty good highs and expansive lows; performing at a high level, they reproduce a wide frequency response from 10Hz to 24kHz. Importantly, they are comfortable headphones, despite the challenges that on-ear designs often have; the band and cushions thankfully dont exert unnecessary pressure on your head or ears.

An interesting feature in these JBL headphones is the Integrated Share Me; it lets you take your music social, allowing you to stream music wirelessly to another Share Me-equipped headphone. Plus, theres an ear-cup-based microphone with Pure Konnexx echo-cancelation technology for hands-free calling with clear voice transmission. In my use, it functioned without any hassle. Basically, you can seamlessly shift from music listening to a phone call at the touch of a button. The headphones built-in rechargeable lithium-ion battery keeps the sound going with 16 hours of uninterrupted play time. And on the occasion that you find yourself without power, use the included 3.5 mm aux cable to play passively.

My takeaways: The JBL E40BT are well-priced and attractively designed headphones with very good audio quality. With their sleek design, they make a visual statement thats as striking as the soundand hence earn a strong recommendation.
