Hi Lussi
When it comes to choosing the best headphones for running there are 3 major parameters you should pay attention to:
1. Durability - are the sweat-proof or waterproof will they survive a sweaty exercise?
2. Sound quality - how will your track sound with your pair of headphones? The bass sound as it should? Will they make irritating distortion sound?
3. Comfort- will your headphones fall from your ears while running? Do they weigh a lot?
If you gather all these parameters you find many brands that make these running headphones and they might be: Bose, Philips, Monster, Sony etc…
But there are also headphones models that were made ESPECIALLY for runners. They combine all what a runner need. You are very welcome to visit my site
