Monster's dual-fold Bluetooth headphones offer excellent performance. The over-ear design ensures a secure fit without causing ear discomfort. The biologic diaphragm and virtual bass provide powerful sound quality. The dual-fold compartment is thin enough to fit in a wallet, making it convenient for carrying during exercise, commuting, or office use. The open listening mode allows for both music enjoyment and ambient sound, making it both practical and comfortable.

Open design is the key to outdoor security: The fat-burning background music in the headphones (with biologic diaphragm + virtual bass, the drum beats are crisp as if you were running on a track) is exciting enough. The bicycle bells behind you and the reminders from passersby can all be heard clearly. You don't have to take off the headphones to maintain safety.When the headphones no longer "block" the ears, listening to music can also be free of restrictions - Monster's double-fold open-belt Bluetooth headphones seamlessly integrate "comfort" and "good sound" into the experience.
The over-ear design closely adheres to the earlobe, preventing shaking during running or head movements while sitting, eliminating the discomfort of a stuffy ear canal, and seamlessly adapting to both commuting and daily scenarios.
The sound quality is also full of surprises: bio-diaphragm speakers + virtual bass technology, with powerful bass extension, making the drum beats of pop music feel truly impactful; the mid and high frequencies are clear and delicate, with the human voice sounding like a gentle whisper close to the ear. With Bluetooth 6.0 chip, connection is instantaneous and transmission is stable, allowing you to immerse in the melody on the subway without any connection loss or lagging.
Mostly understanding the details of commuters, its "double-fold charging case" - when folded, it is as thin as a wallet, fitting into the pocket without taking up space, and when unfolded, it can accommodate the headphones + long battery life. You don't have to worry about charging when going out for a whole day.
There is no compromise between the comfortable "semi-ear" design and the sound quality of the "bone conduction" design. Monster's headphones bring the "open listening" experience to its fullest. Whether it's the wind during morning runs, the noise during commuting, or the soft whispers in the office, it allows you to "hear the world" while having your own sound field.
