Anker Soundcore Liberty 4 Pro（Bluetooth 5.3）【カナル型完全ワイヤレスイヤホン/ウルトラノイズキャンセリング 3.5 / A.C.A.A 4.0 / ハイレゾ/感圧 & スワイプセンサー搭載/PSE技術基準適合】ミッドナイトブラック

The Anker Soundcore Liberty 4 Pro is a feature-packed true wireless earphone that punches well above its weight class, delivering premium-level performance at a remarkably accessible price point of ¥13,990. With Bluetooth 5.3 connectivity, advanced noise cancellation, and high-resolution audio support, this model represents Soundcore's most ambitious effort yet in the competitive TWS market. **Noise Cancellation That Adapts to You** The standout feature here is Ultra Noise Cancelling 3.5, which employs seven dedicated sensors to detect and analyze ambient noise 180 times per minute. This adaptive approach means the earbuds automatically adjust their noise cancellation intensity based on your environment — whether you're on a noisy commuter train, in a bustling café, or walking down a quiet street. The result is a seamless, hands-free ANC experience that consistently delivers impressive silence without requiring manual adjustments. **Sound Quality Powered by A.C.A.A 4.0** Anker's proprietary A.C.A.A 4.0 (Anker Customized Active Acoustics) technology drives the audio experience through an upgraded dual-driver setup: one dedicated to low frequencies and another optimized for mid-to-high frequencies. Each driver receives individually optimized audio signals, resulting in clear, low-distortion sound across the entire frequency range. With Hi-Res audio support, the Liberty 4 Pro delivers impressive detail retrieval — subtle instrumental textures and vocal nuances come through with clarity. Bass is punchy yet controlled, while the mids and highs maintain a transparent, airy quality. **Intuitive Controls Beyond the Earbuds** The Liberty 4 Pro features both pressure-sensitive and swipe sensors on the earbuds themselves, allowing for natural gesture controls like tapping for play/pause and swiping for volume adjustment. What truly sets this model apart, however, is the charging case equipped with a built-in touch bar and screen. This allows users to adjust noise cancellation modes and other settings directly on the case without needing to open the companion app — a genuinely practical innovation that streamlines the daily user experience. **Battery Life That Goes the Distance** Battery performance is excellent: up to 10 hours on the earbuds alone and up to 40 hours with the charging case in normal mode. The fast-charging capability is particularly impressive — just 5 minutes of charging provides approximately 4 hours of playback. This makes the Liberty 4 Pro reliable for long commutes, international flights, or all-day listening sessions. **Comfort and Extras** The canal-type (in-ear) design comes with six sizes of ear tips, making it easy to find a comfortable and secure fit. The package includes the earbuds, charging case, a USB-C to USB-A cable, and documentation. The product is PSE certified for the Japanese market. **Verdict** The Anker Soundcore Liberty 4 Pro delivers a compelling combination of adaptive noise cancellation, high-resolution dual-driver audio, innovative case controls, and marathon battery life. At ¥13,990, it offers outstanding value for anyone seeking a premium true wireless experience without the premium price tag. Whether you're upgrading from a budget pair or looking for a feature-rich daily driver, the Liberty 4 Pro is an excellent choice.
