Overview
An office where you need to hear a colleague, or a street walk where traffic matters, suits the Monster open ear design. The buds rest outside the ear canal and play through dual dynamic drivers, charging in a Type-C case.
Comfort and awareness are the point, since nothing presses into the ear. The open design leaks sound and lets every outside noise in, so it is a poor match for loud trains or quiet libraries.
Who it's for
People who find in-ear tips sore after an hour, or who need to hear announcements, get music without a plug. Flyers and anyone who listens in shared quiet spaces need a sealed design.
Pros and cons
- Nothing enters the ear canal
- Hears the room while listening
- Large total battery reserve
- Recent Bluetooth version
- No noise isolation at all
- Leaks sound to people nearby
- Water rating contradictory in the listing
- Charging cable not listed
Performance notes
With the drivers outside the ear canal, bass and volume depend on how close the bud rests to the opening of the ear. Outside noise mixes freely with the music, which helps awareness but hurts detail on a loud street. Battery life per charge is modest, so the case does the heavy lifting.
