Why customers choose Nexoltic
How do these earbuds stay comfortable for side sleeping?
The Costnzo Sleep Earbuds use a curved, low-profile shape that rests outside the ear canal so there’s no inward pressure against your ear while you lie on a pillow. The form factor reduces the chance of soreness, makes them less likely to dislodge during sleep, and removes the need for ear tips or size adjustments.
- Non-in-ear curved housing fits flush against the outer ear for comfort.
- Low-profile design minimizes pressure when lying on a pillow.
- No interchangeable silicone tips — one size designed for universal fit.
- Lightweight construction reduces sleep-time awareness and discomfort.
What battery life and charging options can I expect?
Each earbud delivers about 5 hours of continuous playback on one charge, and the included charging case increases total available listening time up to 24 hours. A USB-C cable provides faster, more convenient recharges, and the case’s dual LED display shows remaining power so you can plan charging ahead of sleep.
- 5 hours per earbud on a single charge.
- Charging case extends total playback up to 24 hours.
- Up to 180 hours talk time with case recharges included.
- USB-C fast charging and dual LED battery readout for clarity.
How does Sleep Mode work and prevent nighttime interruptions?
Sleep Mode is activated with a four-tap on either earbud, then a single tap within 10 seconds lets you choose an automatic shutdown after 1, 2, or 3 hours. Once a sleep timer is set, buttons lock to avoid accidental presses, so the earbuds won’t switch modes or produce alerts during the night.
- Enter Sleep Mode with a four-tap gesture on either earbud.
- Choose auto-shutdown for 1, 2, or 3 hours via a single tap.
- All buttons lock after setup to prevent accidental changes while sleeping.
- Tapping four times returns the earbuds to regular Music Mode.
Will these earbuds work with my devices and for calls?
Yes — the built-in Bluetooth 5.4 chip ensures stable pairing with phones, tablets, consoles, and computers while reducing interference and power draw. Each earbud features an upgraded noise-canceling microphone array to improve call clarity in everyday noisy environments.
- Bluetooth 5.4 for fast pairing, lower latency, and stable range.
- Compatible with iPhone, Android, Windows, PS4, Xbox, and other Bluetooth devices.
- 8mm dynamic drivers and advanced audio chips for clear stereo sound.
- Noise-canceling microphone improves voice pickup for calls and assistants.
