What’s the Difference Between UE PRO and UE CSX?
Both offer the same sound quality and utilize the same incredible technology. The only difference is the fit. UE PRO in-ear monitors fit deeper into your ear canal for the most secure fit possible — even if you’re doing backflips on stage. UE CSX earphones offer a fit that’s more appropriate for everyday listening.
