Picture 1: I have moved the Sansa Clip to the inner headband and moved it down a little bit but it otherwise looks similar like this:
Picture 2: Creative Aurvana Live headphones with the removable single entry able and without the Sansa Clip:
Picture 3: the modified CAL with Clip on my head (Note they work without noticeable cables!):
As you can see, these are basically CALs (Creative Aurvana Live) modified to contain a Sansa Clip inside the headband. They can alternate in either “wireless” or “wired” mode:
1) “Wireless”, powered by the integrated Sansa Clip; or
2) Wired, simply insert the removable single entry cable and the wireless mode will be immediately terminated. So I can use them with an iPhone in the pocket of my pants.
I got a basic idea from Headfier “rhalf” / Ralph at this thread:
Brian “Pingupenguins”/ at BG Audio took my rough idea and created this gem. He did the following:
1) Enable switchable inputs to the CAL (one input from the integrated Sansa Clip and the other from the removable single entry cable)
2) Converted the dual entry cable to single entry by routing one cable through the headband.
3) MarkL mod the CAL to tighten the bass.
4) Velcro the Sansa Clip to the headband (the Sansa can still be removed easily).
5) Rockboxed the Sansa Clip.
I like Brian’s creation a lot. Because:
1) They sound very good powered by the Clip (MarKL mod and rockbox help a lot here). Sound reference was from well-amped LCD-2s.
2) They are very light, comfortable and can sing in “wireless” mode with a wired sound. I can even jog with my pitbull dog with these on!
3) Cost is very reasonable. I have done some research, the closest commercial product is a discontinued Koss Headphone with 256mb music storage, which looks ugly, heavy and costs USD $100-$150.
Forget about those true wireless headphone/earphones. I have tried the expensive Kleer wireless technology with Sleek Audio’s SA6s. I am not happy with the sound, which lacks resolution, bass and dynamics.
4) The look good on my 2XL sized-head. I have black hairs so it is difficult to see the Sansa Clip.
I am very happy with the results of this project and highly recommend fellow Headfiers to try something similar. I am sure other headphones can be modified in a similar fashion. Brian / “Pingupenguins can offer more DIY details or build you a finished product if you desire.
Thanks for reading my thread and please feel free to comment or ask questions.
