TWS Earbuds QCY HT18 LITE Titanium — True Wireless in-ear headphones

The QCY HT18 LITE Titanium (MeloBuds N70 Lite) are true wireless in-ear earbuds designed for daily listening, calls and active use. They combine Hi-Res Audio Wireless with LDAC support, adaptive active noise cancellation (ANC) and a DualCore Acoustic system with dual drivers for clearer frequency separation. The earbuds offer long battery life with up to 10 hours on a single charge (up to 50 hours with the charging case), Bluetooth 6.0 connectivity, IPX5 water resistance and support for the QCY app for personalization and updates.

Advantages

The DualCore Acoustic design splits frequency ranges across two drivers to improve clarity and reduce distortion, while LDAC and Hi-Res Audio Wireless preserve more detail in wireless playback. Adaptive ANC reduces ambient noise by up to -56 dB and the AI-assisted three-microphone system improves voice clarity for calls. The package also includes multiple ear tip sizes for a secure fit, touch controls, dual-device connection and the QCY app for EQ presets, custom profiles and firmware updates.

Suitable for

• Everyday music listening and podcasts
• Phone and video calls in varied environments
• Commuting and travel
• Workouts and outdoor use (sweat and splash resistant)
• Users who want higher-resolution wireless audio

When it may not be suitable

These earbuds are optimized for portable consumer use and may not satisfy professional studio monitoring needs where absolute flat response and studio-grade isolation are required. Also, while LDAC improves wireless detail, maximum benefit depends on source device support and compatible audio files; without LDAC-capable sources the difference versus standard codecs will be reduced.

How to use

Charge the case and earbuds using the USB-C cable before first use. Open the case near your device to initiate pairing via Bluetooth 6.0 and follow on-screen prompts or use Fast Pair on compatible Android devices. Use the touch controls on the earbuds to play/pause, skip tracks, answer or reject calls, switch ANC modes or call the voice assistant. Install the QCY app to switch noise-canceling modes, select or create EQ presets, update firmware and run the HearX hearing test for a personalized sound profile. Replace silicone ear tips with the included size that provides the best seal for comfort and isolation.

What to consider before purchase

• LDAC benefits require a source device and app that support LDAC and higher-bitrate audio files.
• Battery runtimes vary with ANC usage, volume level and environmental conditions.
• IPX5 protects against sweat and splashes but the earbuds are not fully waterproof for submersion.
• For optimal ANC and sound isolation, choose the correct ear tip size for your ear canal.

Usage recommendations

For best sound and ANC performance, fit the earbuds with the ear tips that form a snug seal, keep firmware updated via the QCY app, and use LDAC-capable devices and high-bitrate audio sources when you want improved wireless audio detail.
