Pros & Cons
👍 Pros
- Features an adjustable ear loop mechanism, ensuring a secure and personalized fit for active users during movement.

👎 Cons
- The clip-on design might not appeal to all users, especially those preferring entirely wireless or traditional over-ear headphones.
- While water-resistant, they are not specified as fully waterproof, which could limit use in heavy rain or for swimming.
- The 9mm dome type drivers, while upgraded, may not deliver the deep bass or expansive soundstage of larger audiophile drivers.
- The Y-type cord, despite having an adjuster, is still a wired connection, which can sometimes tangle or snag during active use.
