Red True Wireless Earphones Bluetooth 5.0

The allentian S11 are compact true wireless earphones in a red finish that use Bluetooth 5.0 for a stable link up to 10 metres. Each earbud holds a 50 mAh cell while the charging case stores 300 mAh, giving about four hours of playback per charge and a full recharge in roughly 60 minutes. The drivers cover a 20 to 20000 Hz frequency range at 16 ohms impedance and draw power from a 5 V input.

Suited for daily commuters and casual listeners

The small, ergonomic shape makes them easy to carry and comfortable for extended wear, so they fit commuters, office workers and anyone wanting cable-free audio without bulk. Buyers who need longer continuous playtime or larger driver units for critical listening should look at other options. No active noise cancellation or transparency mode is mentioned in the specifications.

Four-hour playback from 50 mAh buds

The single figure that decides fit is the roughly four-hour use time provided by the 50 mAh earbud batteries, backed by the 300 mAh case for additional top-ups. If your typical sessions exceed that window you will need a model with higher capacity cells. All other specs support this baseline endurance.

Questions about this item

How much space does the 300 mAh charging case need in a pocket or bag?

The case is described as small and easy to carry, fitting comfortably in most pockets or small compartments without taking up much room.

What is the correct way to pair the earphones via Bluetooth 5.0, and what step do users often miss?

Remove both earbuds from the case to enter pairing mode automatically, then select the device on your phone; the step often missed is taking both buds out together instead of just one.

When will the 50 mAh earbud batteries or 300 mAh case battery need replacement, and how can I tell?

After many charge cycles the 4‑hour play time will drop noticeably; when runtime falls well below that figure the internal cells should be replaced.
