Rose Gold TWS Earphones

These true wireless stereo earphones in rose gold deliver music and call audio through 14 mm drivers with a 25 Hz to 18 kHz frequency response. The ABS and aluminium alloy shell houses a 40 mAh battery per earpiece while the charging case holds 400 mAh. Bluetooth low power consumption is rated at 8 mA and a stable link reaches 10 to 15 metres.

Commuters and casual listeners

The 6 hour listening span and 1.5 hour case recharge suit daily travel or office use. Automatic pairing between the two earpieces removes manual steps each time they are taken out. Buyers who want more storage for offline tracks or builders who need a second card for redundancy should look elsewhere because the earphones have no internal memory and no memory card slot.

110 dB sensitivity spec

At 110 dB ±3 dB sensitivity and 32 Ω impedance the drivers produce high volume from low power sources. A signal to noise ratio of 90 dB or higher keeps background hiss low during quiet passages. If your source device cannot drive 32 Ω loads cleanly you may not reach the rated output level.

Questions about this item

How long will the 40 mAh earphone batteries last before they need replacing?

Each earphone runs for 5-6 hours per charge and the 400 mAh case adds several full recharges, so daily use is covered for a long period before battery wear becomes noticeable.

What stops the music first during a non-stop listening session — battery life or Bluetooth range?

The 5-6 hour earphone runtime is the hard limit; the 10-15 metre Bluetooth link will hold as long as you stay in range, but the cells run out first.

Do the earphones or the charging case get warm when I use them all day?

With only 8 mA draw per earphone and a 1 A charging input, neither the buds nor the case produce noticeable heat during continuous operation.
