2-in-1 Watch with Earbuds

This smart watch integrates true-wireless earbuds into its chassis, letting you take calls or listen to audio without carrying a separate case. It targets users who want a single wrist-worn device for notifications, health tracking and music during workouts or commutes. The 2.03-inch full touch screen provides the control surface for both functions.

Up to 5-day watch battery and 5-hour buds

The watch runs 3 to 5 days on a 250 mAh cell and recharges magnetically in about 2 hours, while the earbuds deliver 4 to 5 hours of playback and top up in 1 hour via pogo pins. Both modules share Bluetooth 5.3 for stable connectivity. Standby reaches 15 days or more for each component.

Heylink app syncs 128 MB of local data

The companion Heylink application aggregates heart-rate, blood-oxygen, blood-pressure and sleep logs stored in the 128 MB onboard memory and pushes them to iOS 11+, Android 7.0+ or HarmonyOS 3.0+ phones. It also manages the five UI themes, custom dials, sports-mode records and notification filters for SMS, WeChat, WhatsApp and other listed apps.

Questions about this item

How do I install the NO. Smart Watch 2-in-1 Earphones and what step do people often miss?

Pair the watch via Bluetooth 5.3 by scanning the QR code in the Heylink APP for one-key connection, then dock the earphones into the watch case so the top pin contacts charge them; users often forget to seat the earphones fully, leaving the pins unconnected.

What maintenance or replacement will the NO. Smart Watch 2-in-1 Earphones need later?

The watch runs 3-5 days per charge and the earphones 4-5 hours; both use magnetic and top-pin charging respectively, so the only ongoing maintenance is regular recharging — no user-replaceable battery or band is mentioned.

What limit appears first during sustained use of the NO. Smart Watch 2-in-1 Earphones?

The earphones reach their 4-5 hour playback limit well before the watch hits its 3-5 day battery life, making earphone runtime the first constraint during continuous activity.
