In the Rai Solo you get a comfortable set of buds, with plenty of fittings to help them nestle neatly in any ear canal, and the over-the-ear cable design means they're not easily yanked out if you're using them on the move. They're well tuned for dynamic range and a very balanced soundstage, managing some beefy bass, airy treble, and a mid-range which isn't squashed by either extreme. They're priced well, they're not too fancy, and their single-driver design sounds great. That's where a set of solid in-ear wired headphones will serve you well, a category which Meze's Rai Solo sits in very happily.
Open-backed headphones are glorious in the right situation, but not so much when there's lots of noise around you or sensitive ears not wishing to listen to your leakage.
