I just tried a pair of Bose A20's and find them to be outstanding. I've been a Lightspeed customer (currently Zulu 2) for a long time and the Bose are better in many regards. The Bose don't seem as heavy or clunky as the Zulus. The sound quality and the ANR on the Bose are much improved over the Zulu, possibly really being worth the price premium over anything else. The only downside I found to the Bose is the placement of the ANR ports on the side are very sensitive to airflow and this can disturb the ANR. This meant adjusting the air vents on the Dash carefully, but not a dealbreaker.
The reason I tried the Bose was because my Zulus were in for repair after only a year and about 600 hours, while my original Zulus had nearly 2000 hours before needing repair. I've sent the Bose back, but only because I want to give my Zulus another shot. But I'm pretty sure I'll be trading them in on a pair of Bose. You can't trade in through Bose though, but you can through other websites.
As for Clarity Aloft, I don't like in ear, but quite a few of my fellow Dash drivers swear by them. But they don't seem very durable to me, as many have had to send them back for repair once a year. if not more. And having to deal with the ear plugs. Plus, I find the price for the Clarity Aloft a bit steep for what they are.
