I am a fan of Logitech. I like their articles: mice, keyboards, speakers ...
But frankly, as I have both models, I can compare ...
Result: If I could have foreseen, I have bought the kit really at Trust above.
It is certainly more expensive but the sound quality is unrivaled.
Logitech home of the kit does its job. Well packed and everything ... but if you put a few euros more, then I suggest you stay at Trust of the kit.
Padrepio.
