Purpose-built listening

The allentian Buds 4 Pro are true wireless earphones built for commuters and office workers who want deep quiet and high-resolution audio. They deliver 48dB ultra-wideband noise reduction, LHDC 4.0 transmission at 96KHz, and an 11mm dual magnetic dynamic unit for detailed sound. The IP54 rating and ergonomic shape suit daily travel and long sessions.

Simple setup, few pitfalls

Pairing uses Bluetooth 5.3 with SBC, AAC and LHDC 4.0 codecs over a 10m open-space range. Pressure-sensitive controls respond quickly and support voice commands, while a six-axis sensor enables 360-degree stereo effects. The main friction point is codec availability: LHDC 4.0 requires a compatible source device, otherwise the connection falls back to AAC or SBC.

Battery scope and limits

Each bud holds a 53mAh cell; the case stores 565mAh and charges via Type-C at 5V 2.3A or Qi wireless. That yields 38 hours total playback with the case, or 9 hours per charge with noise reduction off and 5 hours with deep noise reduction active. Heavy ANC use cuts single-charge time roughly in half, so plan top-ups for full-day trips.

Questions about this item

How can I verify the 48dB noise reduction is active after pairing?

Enable deep noise reduction in the companion app; the LED indicator on the case turns solid white and you should notice an immediate drop in ambient sound.

What accessories are included and what must I purchase separately?

The package contains the earphones, a 565mAh charging case with Type-C port, and ear tips; a Qi wireless charger and any phone adapter are not included.

Which colour option should I choose for the 11mm dual magnetic drivers and LHDC 4.0 support?

Only black is offered, so the single colour variant already provides the 11mm dual magnetic dynamic units, LHDC 4.0 codec, and 96kHz audio capability.
