I have just been trying out the Temco GL42 – Vibraudio Bluetooth Sunglasses for a few days. I was sent an evaluation unit from Keairra’s Eye Wear who is selling them in the US. The shipment arrived in a very nice box with a carrying hard case, a cleaning cloth, a power adapter to recharge batteries and the sunglasses themselves.

I had only read about this technology before but had never experienced it personally. Unlike regular headsets and handsfree devices, they work without a speaker in your ear canal. They use a technology called bone conduction, which transmits sounds through the bones on the front side of your ears. The sound is sent as tiny vibrations through the pads that have to be in place touching the sides of your face. This leaves your hearing canals clear of any obstructions. No obstructions means that they are ideal for motorcyclists or long drives where you want to either listen to some music without losing awareness of your surroundings.

In order to achieve maximum compatibility, this headset uses Bluetooth v1.2. Additionally, they provide two different profiles, one for use as a hands free which uses the microphone placed on the left side, and a headset profile which takes advantage of the pads that are placed on both sides. The sound quality is excellent for calls and surprisingly crisp and clear for listening to music. Please note that this is not an extremely hi-fidelity sound technology, even though it does the job surprisingly well. You will not achieve equivalent sound quality as with a good pair of speakers or headset. The goal in this case is to allow you to keep your music playing while still hearing what happens on your surroundings as you would while driving.

These sunglasses are made of a somewhat bendable plastic, with policarbonate-mirror-coated shades. The sunglass part can be flipped up for night-time use. While in the flipped-down position; the sunglasses are held in place by a magnet so that they don’t accidentally flip-up.

The batteries are rated for 5 hours and have enough juice to go through a solid 4 hours of speaking, after that quality starts dropping out for about an hour and a half. Recharging takes about 3 hours on a regular outlet and for our international readers, please note that the charger is a 110-240 volt automatic adapter that connects into the sunglasses.

Keayrra’s Eye Wear seems to be looking for distributors, so if you are interested, you may want to contact them through their side.

These sunglasses will set you back about $150 with shipping included within the US. You cn buy them at Keayrra’s Eye Wear directly.
