Rose Gold Wireless Earbuds

These rose-gold in-ear headphones use Bluetooth 5.3 for stable wireless audio up to 15 metres away. Active noise cancellation reduces background sound while an integrated microphone supports clear calls. The charging case delivers up to 40 hours of total listening time from multiple recharges. Touch controls handle playback and calls without reaching for a device.

Commuters and active listeners

Suits anyone wanting cable-free stereo sound with noise reduction for travel, work or workouts. The IP7-rated build resists sweat and rain during outdoor exercise. Buyers who need a wired connection or an over-ear fit should consider a different style of headphone.

Bluetooth 5.3 connectivity

The single specification that decides compatibility is the Bluetooth 5.3 wireless link. Your phone, tablet or computer must support this version to pair reliably and maintain the stated 15-metre range.

Questions about this item

How long does the 40-hour battery last before it needs replacing?

The built-in battery delivers up to 40 hours of total playback with the charging case providing four extra charges; battery lifespan depends on usage patterns and charge cycles.

What limits continuous playback during all-day use?

Each earbud runs for 8 hours on a single charge, so the first limit is the earbud battery; the case adds three more full cycles before it must be plugged in.

How much heat or noise do the earbuds produce during extended listening?

In-ear earbuds generate negligible heat and no audible fan noise; the only warmth comes from normal battery discharge during the 8-hour single-charge session.
