I don´t like headphones or earbuds in general

Same here, but then putting the phone speaker on does not sound ideal as well. If you remember, last time my accident in the cycle was because of that Panasonic headphone :) So what you said is absolutely right - it is very dangerous unless you are walking or running at a place where no vehicle movement is happening. Since I am doing the workouts inside our society park (though small), its ok. When I go for a cycle ride, I keep it in the Car - never ever doing the same mistake.

Here in EU, the warranty is 2 years on everything you buy. It´s the law.

That's nice, at least it will ensure quality. Some products here come with just 3 months warranty.
