2-IN-1 (SUBWOOFER】 HEADPHONES-OWS JM13

there! The JM13 Pro is essentially a hybrid device that tries to be both a personal audio solution and a shared one.
​Based on the packaging, here is a breakdown of what this device is and how it likely functions:
​Key Features & Functionality
​2-in-1 Hybrid Design: The most distinctive feature is that the charging case itself doubles as a mini portable speaker (subwoofer). When the earbuds are docked, you can play music out loud; when you take them out, it switches to a personal headset.
​OWS (Open Wearable Stereo): These are "open-ear" headphones. Unlike traditional earbuds that go inside your ear canal, these hook over your ears and sit outside the canal.
​Pros: Better situational awareness and comfort for long wear.
​Cons: More "sound leakage" (people nearby might hear your music) and usually less bass than in-ear models
