JBLUDNG02 Bluetooth Stereo Dongle for Universal Stereo Headset Jack

Small, compact and easy to use J&M A2DP Bluetooth stereo dongle connects to most any stereo source, via the standard 3.5mm 3-con stereo jack, to link and provide 2 channel stereo to J&M’s Bluetooth helmet headsets with 110v wall charger included.

With the nature of Bluetooth® products and the confusion surrounding how they actually work in the motorcycle riding environment, please review the following points prior to your purchase.

J&M Bluetooth Wireless Product Positive Features:

1 - J&M Bluetooth helmet headsets are the best performing Bluetooth headsets on the market today, providing sound and fidelity in the helmet, equal to our best performing corded headsets.

2 - J&M Bluetooth headsets use only the latest Bluetooth software profiles to allow proper linking to the latest Bluetooth enabled cell phones, MP/3 music devices, GPS units etc, along with J&M’s custom dongles.

3 - J&M’s headset designs, quality control and distribution are the best in the business and all J&M products are backed by J&M’s two-year limited warranty. (except Lithium Ion Batteries)
Possible Negative Features:

4 - J&M Bluetooth headsets must be fully charged each time before use, and if the battery goes dead during your day while riding, you will need to stop and re-charge it.

5 - Lithium Ion batteries are relatively expensive and will need to be replaced every 1 ½ - 3 years for proper operation of the headset or dongle, and these batteries are NOT covered by J&M’s 2-year limited warranty.

6 - Some Bluetooth enabled devices may not work together consistently, and/or all of the listed features may not be available/compatible with other Bluetooth devices and Bluetooth headsets.

7 - Bluetooth enabled devices can sometimes unlink from each other for reasons that cannot be readily explained, and then need to be re-linked again for proper operation, causing frustration and inconvenience for the user.

8 - When using one of J&M’s custom dongles operating in the JMAHP Bluetooth profile, connected to a motorcycle audio system with the driver/passenger intercom feature, there is an approximate 90ms delay in the talkback function into the helmet. This delay is not bothersome to most users, but some may object to it compared to the operation and sound of the intercom system when using corded headsets.

9 - In the end you should consider whether or not the higher costs of the Bluetooth headset and/or custom dongles (up to three times higher than the equivalent corded headset solution) along with the sometimes complicated linking/use scenarios, are worth it for your particular riding situation, just to take the place of the simple to use J&M headset cord.

JM Bluetooth Wireless Products - Finally J&M Electronics Have Cut The Cord

J&M Bluetooth® helmet headsets have been available now for a year or more and these first generation units have really broken new ground for those wanting to use cordless helmet headsets.

Almost without exception, they have been using one or more of the available standard Bluetooth headset software configurations of HSP (Headset Profile), HFP (Hands Free Profile), A2DP (Advanced Audio Distribution Profile ((Streaming Stereo)) and AVRCP (Audio Video Remote Control Profile).

These profiles allowed most of these headsets to link to various Bluetooth enabled audio devices, cell phones, GPS/Nav units, I-pods etc. Many of them could also link from one helmet to another, with various functional/wired compromises, depending upon the exact brand or Bluetooth configurations utilized.

The one thing that NONE of these Bluetooth headsets could do, including the first generation J&M® Bluetooth headsets, was to properly link to a system like you would use on a Honda® Gold Wing or Harley® Ultra Classic.

As an example, when using Bluetooth software profile A2DP (2-channel stereo profile) there are no provisions for the signal from the helmet mounted microphone to pass down to the linked device (dongle) simultaneously with the stereo signal from the dongle being transmitted back up to the helmet speakers.

That meant that you could not use the driver/passenger intercom system already built into the audio system on the bike, and you could not talk on the CB radio when you pressed the handlebar mounted TX switch.

J&M has now changed all of that with the release of our own custom Bluetooth software profile, JMAHP (J&M Motorcycle Audio Headset Profile) which allows for simultaneous transmission of both the 2-channel stereo signals and mike signal, back and forth between the headset and dongle.

This new software profile will be included, along with the other standard Bluetooth profiles, in the updated 2008 versions of all J&M Bluetooth helmet headsets, using the enhanced-data-rate (EDR) BlueCoreV® module.

Bluetooth Wireless Products will give these second generation J&M Bluetooth headsets the ability to still link with most all Bluetooth enabled stand alone devices available in the marketplace today, but in addition, be able to link with the new J&M custom dongles for systems like the Honda Gold Wing, Harley Ultra, JMCB-2003 and many other applications to be released.

All of us here want you to be happy with your purchases, so please keep in mind the above considerations BEFORE purchasing any of our Bluetooth headset products.
