I keep my jawbone in my shirt pocket while travelling, but it always seems to fall out. I already have my cellphone attached to my ID lanyard with a spring clip and am wondering if anyone knows where to find a small pouch/case with a spring clip, about the same size as the Jawbone (earpiece only - not the charger). I don't want a large case, and I saw one that a guy had on a plane, but never got a change to ask him about it. Saw the Motorola case, but it was too clunky for me. Thanks in advance!
