Anker Soundcore C40i（Bluetooth 5.4）【オープンイヤー型ワイヤレスイヤホン/イヤーカフ/ IPX4防水規格/ 最大21時間再生 / マルチポイント接続】クリアブラック

Pros

• Open-ear design that doesn’t block your ears, with less pressure even during long use
• Bluetooth 5.4 support for more stable connectivity (depending on your environment)
• Multi-point support makes it smooth to switch between your smartphone and another device
• IPX4 water resistance is designed for everyday use, with consideration for light sweat and water splashes

Things to Note

• Sound isolation is weaker than that of closed-back earbuds, so you may need to adjust the volume in noisy places
• Because it feels more open, the punchy impact of bass may vary depending on personal preference compared to closed-back models
