Csasan V90

The Csasan V90 nails battery life with 48 hours total and an IPX7 rating for workouts. Connectivity is strong too. But comfort and build quality are weak spots. Buy these for the gym, not for all-day listening.

The 13mm dynamic drivers push out punchy bass, which is exactly what you want for workout playlists. Sound quality sits at 57th percentile, so it's fine but not going to impress an audiophile. The ENC mic does a decent job cutting background noise, landing at 68th percentile. Bluetooth 5.3 is rock solid and the multipoint connection is a nice touch for switching between a phone and laptop. The real standout is battery: 8 hours per charge and 48 total with the case. That's top-tier for this category. But the comfort score of 29th percentile is a red flag. Ear hooks that don't fit well become painful after 30 minutes, no matter how good the battery is.

Against the Sony WF-1000XM6 and Apple AirPods Pro 3, the Csasan V90 wins on battery life and price but loses everywhere else. The Sony and Apple both have far better ANC, sound, and build quality. The Technics EAH-AZ100 is in another league entirely for audio. Where the V90 makes sense is against other budget options like the Soundcore P31i or EarFun Air Pro 4+. The Csasan beats both on battery and water resistance, but the Soundcore likely has better comfort and the EarFun has stronger overall sound. It's a trade-off between endurance and everyday comfort.

There's no price listed, which makes value tough to judge. But given the budget positioning and the 48.1 out of 100 budget score, this is clearly aimed at the lower end of the market. You're getting flagship-level battery life and solid connectivity for what's likely a fraction of the cost of the Sony WF-1000XM6 or Apple AirPods Pro 3. The trade-off is comfort and build. If you can find these on sale and they fit your ears, they're a steal for gym use.

The Csasan V90 is an ear-hook style budget earbud aimed squarely at runners and gym rats. It packs Bluetooth 5.3, a 48-hour total battery life, and an IPX7 rating into a design that wraps around your ear. The spec sheet reads like a wish list for active users, but the real-world scores tell a more mixed story.

Battery life is the star here, landing in the 91st percentile. Connectivity and ANC are also strong. But comfort and build quality drag the overall score down to 47.7 out of 100. It's a classic case of great features on paper, with some compromises you'll feel in your ears.

Skip these if you have sensitive ears or plan to wear them for hours at a time. The comfort score is in the bottom third, so the ear hooks may cause fatigue. If you care about sound quality or build materials, look at the Soundcore P31i or spend more on the EarFun Air Pro 4+. And if you need top-tier ANC for flights or noisy offices, the Sony WF-1000XM6 is worth the extra cash.

The Csasan V90 is for people who prioritize battery life and sweat resistance above all else. If you're a marathon runner or someone who forgets to charge their earbuds for days, this is a solid pick. The ear-hook design will keep them in place during intense movement, assuming they fit your ears. Just don't expect premium sound or all-day comfort.
