Real-World Testing & Performance
I tested the NW-WS623 across multiple environments, from swimming pools to paddle boarding and trail running. Here’s how it performed:
Sound Quality
Underwater, the sound is naturally more muted, but the sealed swim tips keep audio crisp and rhythmic. On land, the dual-driver system delivers a surprisingly full profile: punchy bass, clear mids, and sharp but non-fatiguing highs. Music feels energetic and immersive, making long workouts less monotonous.

Battery Life
Battery performance is outstanding. Expect up to 12 hours in MP3 mode and 4–6 hours via Bluetooth. Quick charge is another huge plus: 3 minutes of charging = 60 minutes of playback. Perfect for last-minute sessions.
Durability & Controls
The headset stayed locked in place during freestyle swims, paddle boarding, and even surf entries. Buttons remain responsive even when submerged—no mushy feedback or lag. The rugged design withstood saltwater exposure, drops, and sand without issue.
Call Quality
Although not its primary function, call quality is surprisingly good. Two quick calls during a run came through clearly, even with wind noise. Ideal if you want to remain reachable while training solo.

Who Is the Sony NW-WS623 For?
This headset is perfect for:
- Swimmers & triathletes – full waterproofing + secure fit
- Runners & paddle boarders – lightweight, no phone required
- Fitness enthusiasts – long battery life for extended training sessions
- Beachgoers – durable, saltwater-friendly build

Final Verdict – Freedom to Train Without a Phone
The Sony NW-WS623 Waterproof Sports Headphones deliver on their promise: freeing you from your phone while keeping your music alive in even the harshest environments. With excellent waterproofing, reliable fit, strong sound quality, and battery life that keeps up with training, these are the ideal companion for swimmers, paddle boarders, and outdoor athletes. The only trade-off? Limited onboard storage and no app-based EQ. But for under $150, the performance is exceptional.
