Around 200-230€ in Germany. I have a model where the human voice frequencies have a bit less attenuation, absolutely perfect for noisy bars where you want to hear your buddy at the same table.

Less perfect for noisy restaurants as eating will make your ears to wiggle a bit, causing some shifting sounds if you are wearing plugs. But great again for noisy public transport and flights. I always keep them in a small pouch in my pocket.
