A smartwatch with music storage only matters when it lets you leave your phone behind and still listen to your own songs.
The Kospet Tank M4 is worth attention because it combines 32GB local storage with offline maps, so music and navigation can stay on your wrist during workouts and outdoor trips.

Why a Smartwatch With Music Storage Matters for Workouts and Outdoor Trips
A smartwatch with music storage solves one clear problem: carrying a phone feels annoying when you run, lift, or hike. Music stored on the watch means your playlist stays available even when your phone is in a locker or backpack, and the Tank M4 is built around that “phone-free” idea with local files and offline use.
A smartwatch with music storage also keeps your routine stable when signal is weak. Streaming depends on apps, accounts, and downloads, while local MP3 files stay usable after you copy them once, so the experience stays simple and repeatable.
Tip: Treat “music storage” as “local files on the watch,” not “music control on your phone.” Local storage is the difference between leaving your phone behind and still hearing your playlist.
Tank M4 Music Storage: What You Actually Get
The Kospet Tank M4 gives you 32GB storage designed for music and offline maps, and KOSPET states that storage is enough for about 5,000 songs or about 100 offline maps (real capacity depends on file size and system space).
The Kospet Tank M4 keeps navigation in the same “no-phone” lane by supporting route import and offline map support, including importing GPX or KML route files through the Apexmove app, and downloading offline maps using a computer or tablet.
And also targets outdoor tracking accuracy with dual-band (L1+L5) positioning and support for six satellite systems, which is the right direction for hikers who hate messy tracks under trees or near cliffs.
How to Put Music on Tank M4 and Listen Without a Phone
The simplest win of the Tank M4 is that it uses direct file transfer for music. KOSPET describes a setup where you connect the watch to a computer with the charging cable, the computer recognizes it like an external drive, and you drag and drop MP3 files into the watch’s music folder.
The “phone-free” part stays real because the Tank M4 pairs directly to Bluetooth headphones. That pairing path means the watch can play stored songs to your earbuds without needing your phone nearby.
Tip: After you copy music, build a short “workout playlist” first (like 30–60 minutes). It makes testing faster, and you can confirm playback and controls before loading a huge library.
Tank M4 Battery Life for Music Storage and GPS Use
Battery claims mean nothing unless they include heavy tasks like GPS tracking and Bluetooth audio. KOSPET lists up to 21–22 hours of continuous GPS use, which covers long day hikes and long training days without the watch becoming a dead screen halfway through.
Battery planning gets easier when you also have the “everyday” numbers. KOSPET lists up to 14–15 days typical use, up to 9–10 days heavy use, and up to 5–6 days with always-on display mode, so you can set expectations for how often charging shows up in your week.

Tip: GPS + Bluetooth audio is a high-drain combo on any watch. Use the published “continuous GPS” figure as your reality check, not the “days” number.
Tank M4 Wins On Value
Because it focuses on local MP3 storage instead of making offline listening depend on streaming apps and subscriptions. That approach avoids ongoing costs and avoids the “app support” headaches that often come with music on watches.
The Kospet Tank M4 also stands out because it pairs music storage with offline map support in the same 32GB space, so one device covers both entertainment and trail basics. Many buyers search these two needs together for a reason: music keeps pace steady, and offline maps keep the route steady.
Conclusion
The Kospet Tank M4 is worth it because it delivers the exact feature most people mean by “smartwatch with music storage”: store MP3s locally, pair earbuds, and play without a phone, backed by 32GB storage and clear battery figures for GPS use.
The Kospet Tank M4 becomes even more practical because the same storage is built to hold offline maps and imported routes, so outdoor users get music and navigation in one device instead of juggling tools.
