The EarFun OpenJump are open-ear earbuds with IPX7 protection and up to 42 hours total battery life, emphasizing situational awareness. Their open design reduces deep bass and the touch interface can be finicky. Perfect for active users who need water resistance and awareness.

The GNMN V7 earbuds provide sport-focused design with IPX7 waterproofing, 16 mm drivers and up to 96 hours of total playback. They sacrifice consistent ANC performance and are relatively heavy for in-ear earbuds. Best suited for athletes and active users needing durable, long-lasting earbuds.
