Sound Quality

Packed with 10mm drivers, the Rulefiss i25 earbuds produce impressive stereo sound with punchy bass and clear mids and highs. The sound profile is quite balanced with good emphasis on the low end, making these great for listening to music of all genres. Volume levels go sufficiently loud thanks to the Bluetooth 5.3 chips.

For phone calls, the built-in microphones capture your voice clearly to enable crisp and smooth conversations.

Comfort and Fit

The Rulefiss i25 earbuds come with three sizes of silicone eartips so you can find the perfect fit for your ears. Once in place, the earbuds feel very lightweight and comfortable. The ear hooks keep the buds securely in position during workouts and intense activity.

The IP7 rating means the earbuds can withstand sweat, rain, and water splashes with no problem. You don’t have to worry about damaging them during your toughest training sessions.

Battery Life

Battery life is impressive at up to 8 hours of continuous playback per charge. When combined with the charging case, you get up to 48 hours before needing to recharge via USB-C. Quick charging gives you an hour of use from just 10 minutes of charging.

The case displays the battery level with LED indicators so you always know how much juice is left.

Seamless Wireless Connectivity

The Rulefiss i25 earbuds utilize the latest Bluetooth 5.3 chipset for fast and stable wireless connectivity to your devices. Once paired initially, the earbuds will automatically connect to your smartphone, tablet, or computer each time you remove them from the charging case.

Reviewers consistently report buttery smooth streaming even when leaving their phone in another room or outdoors. Bluetooth range is rated to 10 meters or 33 feet officially. But some users find they can go even farther, up to 15-20 meters, before audio starts cutting out. This is far better than older Bluetooth versions.

Multi-point connectivity allows the Rulefiss i25 earbuds to remain paired with two devices simultaneously. You can be listening to music on your laptop and still answer calls from your paired smartphone without manually switching between devices.

Pairing is a breeze with most devices thanks to quick recognition and the automatic left/right earbud pairing sequence. Once the initial pairing is complete, the earbuds will automatically turn on and connect to your device as soon as you take them out of the charging case. Re-pairing is seldom necessary.

IPX7 Waterproof Protection

The Rulefiss i25 earbuds carry an IPX7 rating which means they are able to withstand being submerged in 1 meter of water for up to 30 minutes. This makes them fully sweatproof and splashproof for the most strenuous workouts, runs in the rain, and poolside listening.

Reviewers confirm using the Rulefiss earbuds for activities like weightlifting, cycling, yoga, and more without any water damage even when drenched in sweat. The nano-coating adequately seals out moisture from the earbud’s inner electronics and drivers.

While the water protection ensures rain and sweat won’t be an issue, the earbuds are not suitable for swimming or showering. The IPX7 rating does allow for accidental drops into water but not continuous, underwater submersion. For swimming, a dedicated pair of waterproof aquatic earbuds would be a better choice. But for everyday exercise and use, the iRulefiss i25 earbuds have more than adequate water protection.

Great For:

The Rulefiss i25 earbuds are ideal for workouts, running, sports, gym sessions, and general everyday use. The combination of sweatproofing, stability, and pumped up sound makes them especially suitable for exercise. The long battery life also makes them great for all-day listening at home or work.

User Feedback Analysis

The Rulefiss i25 earbuds have received overwhelmingly positive feedback from buyers. Out of over 1,500 global ratings, they average 4.1 out of 5 stars, indicating highly satisfied customers.

When it comes to comfort, the ergonomic earhook design gets consistent praise for staying securely in place during exercise and active use. Reviewers say the earbuds feel lightweight and comfortable enough for all-day wear. The inclusion of 3 sizes of eartips is a major plus for achieving a customized fit.

In terms of sound quality, buyers describe the audio reproduction as surprisingly clear, lively, and balanced - especially for budget wireless earbuds. The bass has noticeable thump without muddying the mids and highs. Volume levels can be boosted high enough for noisy environments. Many mention the sound competing with earbuds double the price.

The touch controls work reliably for most users and allow easy control of music, calls, volume and voice assistants. Some do find the touch sensors slightly too sensitive out of the box but this can be adjusted.

Connectivity is rated as excellent by the vast majority. Linking to devices is quick and the Bluetooth 5.3 chip provides uninterrupted streaming even at extended distances. Very few disconnection issues are reported.

When it comes to battery life, almost all buyers are impressed with both the 6-8 hour bud battery and 40+ hour charging case capacity. This eliminates the need to recharge frequently.

In terms of downsides, a handful of users report issues with one earbud failing after a few months of use. And the waterproofing may not hold up for swimmers. But Rulefiss does back the earbuds with a 1 year warranty for factory defects.
