A2DP for W810i and HX2750 solution with i.tech Blueband and Bluecon

GOING WIRELESS WITH MUSIC When i got my W810i, having a walkman again was quite a lot of fun. But it slowly wore out when i had to unravel the always tangled headsets. I really hated that! So the only way was to unwire. I recently purchased yet another Bluetooth device. The i-tech blueband Bluetooth Headset. These work with the new A2DP profile found on newer bluetooth v2 devices. Unfortunately, my W810i does not have A2DP so it can't directly stream music to my new headphones. I have to use their Bluecon dongle. The great thing about this pair of headsets is that it connect to (at least) 2 devices simultaneously. Which means, that as i am listening to music streaming from the dongle, i can also have it simultaneously paired to my w810i handsfree profile. It works perfectly. When calls come in, the walkman stops, and the call can be received on the Blueband headset. After the conversation ends, the music comes back on. Great foresight on the part of the iTech blueband design. This is the solution to the w810i problem of not having an A2DP profile. SE will probably not upgrade the bluetooth stack in the w810i to support A2dp so this setup seems to be the best choice. The only extra thing is having a dongle sticking out of the W810i while listening to music.
As you can see in the pictures, the first picture shows the back of my phone and the back of the A2Dp dongle stuck with velcro branded low profile pads. The low profile furry black velcro blends with the color of my phone and the low profile hooks are stuck to the back of the a2dp dongle. With the short headphone adapter for the Sony Ericsson Fastport, there's no mess of wires and it make a good stand at a 45 degree angle for viewing movies too.. When the Bluetooth dongle is not in use, the velcropad on my phone is unobtrusive. I have also been using the headset with my iPAQ HX2750 PDA. Originaly, my HX2750 also does not come with A2DP support. but I've found the patch which enables my HX2750 running WM2003se to utilize High quality audio setup. This is similar to A2DP support. That patch is available here: http://www.nationalsportssymposium2007.com/misc/a2dpUpdateBroadcom.cab The quality of music coming from the Blueband headset is really quite great. Large headphones are definately much better than the little puny headphones. Overall a satisfactory gadget.
The featured bluetooth headset can be purchased from my friend Jimmy, available at http://forum.lowyat.net/topic/170005 Please mention that you were recommended from the Prometheus blog.. he may lower the prices for u.
Newly made wire. I cut up a pair of fake sony headphones and shortened the wire.Resoldered to the fastport plug. It now has a mic, the button and the sony walkman logo. Usable as a handsfree with any stereo headphones. Showing you the original wire for comparison.

Clip Mod for Sony Ericsson IV-835 Bluetooth Headset

I finally modded my IV-835 bluetooth headset. Its better now that i don't have to stick it in my ear all the time. I can now clip it to my shirt like a pen. I don't know why sony doesn't make a similar clip. My design is not refined yet, so it has a rough finishing, but its functional. The clip need not be removed to stick the bluetooth into your ear. If sony made this, they could fabricate it to have a lower profile, which would make it fit better to the ear and look nicer too. I'm trying to find someone to fabricate the mould.. anyone knows who fabricates such moulds? Making it... I bought the cheapest charger i could find, which was a 10 ringgit car charger with the fastport plug. Cut the fastport plug into 2. After that, i cut off the stem off a pen, and drilled a whole into the pen cover. O then screwed the stem of the pen cover to the plug and superglued it for some sturdiness. Works well, now i can clip the bluetooth to my pocket when its not stuck to my ear. This clip works well with the iv-835 has the headset does not have a loop to get in the way when clipped to my pocket.
