I know Astrotec other Earbuds will be Great, because those are even Higher end Astrotec True Wireless Earbuds. With the mids there was something in the 1200 Hz range that was a bit spikeyOn the highs, I could clearly hear almost to 15,000 Hz range. I know its hard. Theres several earpieces included which allows you to adjust to your ear size and it comes with an arm to put over your head. Dont notice much wind noise but they certainly reduce fuel economy. Awesome sound quality. The left click randomly stopped working one day. It actuality, it is a painted gray color. Best of all, it is made with 50% post-consumer material, and the cardboard it came on is 100% post-consumer material! This can be helped some if straps are heated (with blow-drier) and then stretched out.
