The 360° dynamic sound provides a rich, balanced experience, and the dual 12mm drivers deliver crisp highs and clear mid-range tones. For most users, the sound quality is clear enough for casual listening and active use, such as workouts or commuting.

However, some buyers felt the bass response could be more robust. While the sound is generally clear, those looking for deep, punchy bass might find it lacking. This can be especially noticeable for bass-heavy genres like EDM or hip-hop.

Battery Life

92%

The impressive 30 hours of total playback with the charging case stands out as a major benefit. Many users find the extended battery life particularly useful during long trips, outdoor activities, or daily commutes. With 6 hours of playback on a single charge, the headphones offer a reliable experience that lasts through various activities without needing frequent recharging.

While the battery life is generally praised, a few users noted that it could still feel a bit short for marathon listening sessions. Some individuals who frequently listen for 8+ hours straight may find themselves needing a recharge earlier than expected, especially if they forget to charge the case.

Water Resistance

The IPX5 water resistance is a standout feature for active users. Whether it's rain, sweat from a workout, or an occasional splash, these headphones can handle it all without concern. Buyers who use the headphones for outdoor sports or intense physical activities appreciate the durability in challenging environments.

Despite the strong water resistance rating, some users pointed out that the headphones may not perform as well in heavy downpours or extreme conditions. While fine for moderate exposure, prolonged immersion or heavy rain might cause issues, limiting their use in certain weather conditions.

The comfortable fit and sweatproof design make them ideal for running, cycling, or gym sessions. Many users mentioned that they are a perfect balance between comfort, performance, and safety during physical activities.

A few users did mention that the headphones might not stay as securely in place during more vigorous workouts, such as high-impact exercises or intense running. The lack of a more snug fit can occasionally lead to the headphones shifting or feeling less stable during fast-paced movements.

Fit and Stability

83%

The lightweight, open-ear design offers a comfortable and stable fit for most users, even for extended periods. The flexible ear hooks are adjustable, making it easier to customize the fit for different head shapes and sizes. This adaptability is appreciated by those who typically find traditional in-ear designs uncomfortable or cumbersome.

However, some users found the fit less stable during certain activities, particularly those involving intense movement. While the adjustable ear hooks help, a few buyers felt the design could benefit from additional features to ensure a firmer hold during vigorous workouts or fast running.

Bass Performance

72%

28%

For many users, the bass is sufficient for general listening, especially in more balanced genres like pop or acoustic music. The headphones perform well in providing overall clarity and detail, with some users reporting satisfactory audio for non-bass-heavy content.

However, several users noted that the bass performance is underwhelming, especially for genres that demand deeper low-end response. Users accustomed to more bass-heavy headphones found the low-end lacking, which made the overall sound less dynamic, especially for certain music styles like hip-hop or electronic.

The sound balance on these headphones offers an overall pleasant listening experience. Many users appreciated the clarity of vocals and mids, which are well-defined without distortion. The overall tuning is decent for most casual listening sessions, especially with lighter music genres.

This led to mixed opinions about its suitability for critical listening.

The flexible ear hooks and low-profile construction make them easy to wear for long hours without feeling bulky.
