SKU CH-HZH1-KYZXY

True wireless earbuds with Bluetooth 5.3, built-in MP3 storage via microSD, 8-10 hour playback, 13 mm drivers and IPX-rated comfort for sport

  • Bluetooth 5.3 delivers stable audio up to 10 m
  • 13 mm drivers produce Hi-Fi surround sound
  • Silicone tips stay secure during sport activity
  • Built-in card reader plays MP3 files without extra device
  • 800 mAh case extends listening time for hours

True Wireless Earbuds With Onboard MP3 Playback

These NShi earbuds combine Bluetooth 5.3 streaming with a built-in card slot so you can listen to music stored on a microSD card without a phone. The 13 mm drivers deliver a 100-20000 Hz frequency response and 97 dB sensitivity for clear audio during sport or commute. Silicone eartips keep the 83 g set stable during movement.

Sustained Use Battery And Thermal Behaviour

Each earbud holds an 80 mAh cell giving 8-10 hours of talk or music time, while the charging compartment adds 800 mAh for multiple top-ups. Both the buds and the case recharge fully in 2 hours via the Type-C port at 5 V. The specified operating range of -20 °C to +60 °C means performance stays consistent in cold winters or hot summers.

Simple Setup With One Common Pitfall

Pairing follows standard Bluetooth 5.3 HFP, HSP, A2DP and AVRCP profiles and works up to 10 m from the source; the adapter function lets you plug the case into a computer without drivers. A microSD card is not included, so the MP3 mode remains inactive until you supply one. The 320 Ω impedance is unusually high for portable gear and may produce lower volume on some laptop or phone outputs.

Questions about this item

Will the earbuds overheat or lose battery quickly if I wear them all day?

Music playback lasts 8-10 hours per charge and the case adds 800 mAh capacity. The 80 mAh earbud batteries recharge in 2 hours via the TYPE-C port. Operating temperature range is -20°C to +60°C.

What must I already own to use the MP3 player function?

A microSD card is required because the memory card is not included. The built-in card reader lets you load files directly without another reader. Bluetooth 5.3 and a USB-C power source are needed for wireless use and charging.

Can I pair these with a desktop that has no Bluetooth?

The supplier notes a Bluetooth adapter function that works without drivers when plugged directly into a computer, letting you add wireless audio to older hardware.
