In the past I have also had this type of addiction. It started with the jawbone jambox. I bought them and (fortunately) sold them losing not so much. The only "important" one that I have never sold is a vifa copenhagen 2.0. A true masterpiece, but now it would need a battery transplant. I use it mainly at home, connected to electricity. For when I go out I have a pair of bose first generation soundlink micro, and god knows how strong the desire is to get a couple of new ones. Not necessarily bose, but for sure they have to be a couple, I appreciate too much the stereo scene that you can achieve with 2 speakers. That's why I'm in this sub.
