SKU CH-P20P-HTP5R

A Bluetooth 4.1 receiver adds wireless audio to any 3.5 mm headphones and supports two paired phones simultaneously

  • Bluetooth 4.1 enables wireless music streaming

  • 60 mAh battery powers extended listening sessions
  • 5 mm jack plugs into any wired headphones

Portable Wireless Audio Adapter

The ESTONE AX-03 is a Bluetooth 4.1 receiver that adds wireless streaming to any device with a 3.5mm input. It serves listeners who want to use existing wired headphones or speakers without a direct cable connection to a phone or tablet. The unit supports simultaneous pairing with two mobile phones for quick switching between sources.

Simple Integration With Wired Gear

A 3.5mm plug connects the adapter directly into a headphone jack or auxiliary port, requiring no extra cables or power bricks during use. Its built-in 3.7V 60mAh battery removes the need for a nearby mains outlet while listening. The compact ABS body keeps the setup light and unobtrusive on a desk or in a bag.

Steady Streaming On A Small Cell

Bluetooth 4.1 maintains a stable link for music and calls within typical indoor range. The modest 60mAh capacity limits continuous playtime compared with larger receivers, so extended sessions will need a recharge break. Users who need all-day operation without interruption should consider a device with a higher-capacity battery.
