These true wireless earbuds deliver hybrid active noise cancellation up to 42dB and 12.4mm dynamic drivers for balanced audio.

Bluetooth 5.4 Connectivity Limits

Bluetooth 5.4 provides stable wireless performance within standard range, though walls and interference can reduce effective distance.

Buyers needing multi-point pairing or aptX codec support should verify compatibility before purchase.

Questions about this item

Will the 45mAh earbud batteries need replacing after a certain number of charge cycles?

The earbuds use 45mAh lithium-ion cells that will gradually lose capacity over hundreds of cycles; when runtime drops noticeably you can replace the buds themselves since the batteries are not user-serviceable.

What limits continuous use before the 36-hour total battery is exhausted?

Each bud runs up to 8 hours on a single charge and the 475mAh case adds further charges to reach the 36-hour total; the first limit you hit is the 8-hour per-charge span of the buds.

How much heat or noise do the 12.4mm drivers and ANC produce during all-day wear?

The 12.4mm dynamic drivers and 42dB hybrid ANC operate silently with no audible fan or mechanical noise; the earbuds stay cool against the ear because they draw only milliwatts from the 45mAh cells.
