In-Ear Headphones with Bluetooth 5.4

These in-ear headphones use Bluetooth 5.4 for wireless audio on smartphones, tablets, laptops and smart TVs. Active noise cancellation reduces low and mid-frequency noise while the 10 mm drivers cover a 5 Hz to 20 kHz response. The 32 ohm impedance and 99.5 dB sensitivity suit everyday listening across iOS and Android devices.

LED Case Display and App EQ

The charging case includes an LED readout that shows remaining power for both buds and case. The HAVIT LIFE app adds six preset EQ modes such as rock, classical and jazz plus a manual adjuster. Four ear-tip sizes from XS to L are supplied to improve passive seal and therefore the effectiveness of the active noise cancellation.

40 Hour Total Playtime

A single charge gives up to 6.5 hours of playback and the case extends this to 40 hours total. Recharging the case takes about 2 hours. The 0.109 kg weight keeps the buds light for long sessions, while multipoint compatibility lets you switch between two paired devices without re-pairing.

Questions about this item

When will the earbud batteries need replacing if I use them daily?

Each earbud delivers up to 6.5 hours per charge and the case extends total playtime to 40 hours; lithium-ion cells typically last several hundred cycles before capacity drops noticeably

What limits continuous listening during a long workday?

The earbuds run for 6.5 hours on a single charge, so a midday top-up in the case is required for all-day sessions

How much heat or noise do the buds produce during hours of ANC use?

In-ear design generates negligible heat and no audible fan noise; active noise cancellation runs silently on the 10 mm drivers while Bluetooth 5.4 maintains a stable link
