GlobalSat BTH-820 and Audio Gateway BTA-830
Wireless audio headsets have been around for some time using proprietary analog and digital transmission protocols. These technologies were hampered by the constant tuning required by analog systems and the fact that they could only be used with accessories from the same manufacturer.
Two weeks ago, I’ve received my latest Bluetooth gadget, the Globalsat Bluetooth Entertainment Pack. The Globalsat Bluetooth Entertainment Pack is a combination of Globelsat’s BTA-830 audio gateway which can be connected to virtually any audio device with an audio out option and the BTH-820 Bluetooth headset and during the past days, I had some exciting chances to test it while I was snowboarding, on a business trip, in the hotel, in the office and even at home and I’ve connected it to virtually every gadget I’m carrying abroad (my Smartphones, my Portable Media Center, my Apple iPod, my Notebook and my Pocket PC) or I have at home (my Windows XP Media Center).
The Bluetooth technology standard is finally achieving global acceptance so that any Bluetooth enabled device can connect to any other Bluetooth enabled devices in close proximity. For the newbies, Bluetooth enabled devices connect and communicate wirelessly through short-range, ad hoc networks called piconets. Piconets support up to seven devices simultaneously.

The Bluetooth Entertainment Pack consists a sender/receiver that connects to any audio source, for instance your iPod and a Bluetooth headset. The headset is simple plug-and-go device which supports the standard Bluetooth A2DP for clear stereo sound streaming and the Bluetooth AVRCP profile for remote control as well as the standard Bluetooth headset profile to use it as a headset for mobile phones.
Using the latest Bluetooth technologies the Audio Gateway transmits crystal clear digital sound to compatible Bluetooth audio headsets up to 10m away.
In the box, from left top to right bottom: USB to dual-mini USB cable for charging (the Bluetooth headset and gateway), 110 - 240 V USB charger, Bluetooth headset main unit including microphone, remote control and 3.5 stereo plug, stereo headset to be plugged into the main unit, Bluetooth audio gateway.
Thanks to the used A2DP and AVRCP Bluetooth profiles, it should works with any compatible Bluetooth stereo equipment (like Windows Mobile 5.0 devices with AKU 2 which means you don’t have to use the audio gateway at all but also with Bluetooth equipments from other manufactures like the Motorola Home Entertainment Solution HT820/DC800).
The backbone of the standard and the bane for users are device service descriptions known as profiles. Profiles are standards based definitions of how device types communicate with each other. Without matching profiles, Bluetooth enabled devices are unable to properly communicate with each other. For example the Advanced Audio Distribution Profile (A2DP) allows a device such as Bluetooth enabled pair of headphones to receive a stereo audio data stream from a Bluetooth enabled PDA or Music Player with the same profile.
The sales box contains everything you need to start: a USB to dual-mini USB cable for charging (the Bluetooth main-unit and gateway simultaneously while carrying one cable and charger only), the 110 - 240 V USB charger which can be used world wide, the Bluetooth headset main-unit which also includes the microphone and which can be used as a headset for your mobile phone and also includes the remote control and 3.5 mm stereo jack, a stereo headset to be plugged into the main-unit and the Bluetooth audio gateway which also has a 3.5 mm stereo plug.
I will give it a test over the next days including an outdoor test next weekend when I’m out for snowboarding; please stay tuned for my review! But at least, it doesn’t looks as geeky as the Motorola Bluetooth headset looks like.
If your PDA or Music Player does not support the A2DP profile you will not be able to use the headphones. GlobalSat has implemented the A2DP profile in their Bluetooth version 1.2 class 2 certified stereo headset receiver/transmitter BTH-820 and audio gateway transmitter BTA-830. Let’s see if they can provide quality Bluetooth stereo sound!
