Design and comfort
It’s the Zenith Pro that’ll immediately catch your eye. It features a unique and eye-pleasing half-transparent charging case. It may be bulkier than the Ivy Pro, which features a pill-shaped case with a matte finish on the stem; however, it doesn’t feel heavy at all. The Zenith Pro has an IPX4 rating, which is suitable for workouts. Despite being bulkier, they comfortably fit in any pocket, and I never felt the need to remove them from my ear canal during extended listening sessions. The case, though, isn’t the best out there. Yes, taking them out and thereafter putting them back in is a pain in the butt. Oftentimes, they didn’t sit right.
