I used a Jabra earbud for my Samsung phone for 2 years, and while I was disappointed I couldn't use the same set up for my new Nokia 8200, Jabra did a great job with this product. There wasn't a whole lot that needed improving in the first place, the three ear piece sides in either left or right allow a comfortable fit, the microphone does a great job of picking everything up, and the speaker works great (you can hear over just about any level of ambient noise). But Jabra did make some very good improvements both superficially, gone are the neon ear pieces, which have been replaced by more subtle colors, but structurally as well. The earpiece itself is much sturdier than its predecessor, the sized earpieces fit much more snuggly to the speaker/microphone so that they can't slide off, and finally the on/off switch is very handy.There wasn't much room to improve this product, as it is already fantastic, but Jabra managed to do so. This is a product that actually makes the phone better, and I highly recommend it.
