Amazonベーシック 完全ワイヤレスイヤホン Bluetooth5.4 IPX4防水 マイク付きインイヤー型 充電ケース付き ブラック

The Amazon Basics True Wireless Earbuds (B0DQSJ4QHB) deliver a surprisingly well-rounded package for their budget-friendly price of ¥2,384 (approximately $16 USD). Equipped with Bluetooth 5.4, IPX4 water resistance, and up to 28 hours of total battery life, these earbuds aim to cover all the essentials for everyday listening. **Design and Comfort** These in-ear style earbuds come in a clean black finish that feels appropriately understated for the Amazon Basics brand. Three sizes of ear tips (S/M/L) are included in the box, allowing users to find their ideal fit. The inclusion of multiple ear tip sizes is a welcome touch at this price point, as a proper seal is crucial for both comfort and sound quality during extended listening sessions. **Connectivity** Bluetooth 5.4 is the latest standard in wireless connectivity, and its inclusion here is notable for a budget product. This newer protocol promises more stable connections and improved power efficiency compared to older Bluetooth versions. The pairing process is straightforward — simply place the earbuds in the charging case, close and reopen the lid, and they enter pairing mode automatically. Subsequent reconnections are handled automatically when the case is opened, which is a convenient, hassle-free experience. **Battery Life and Water Resistance** Battery performance is one of the standout features of these earbuds. The earbuds themselves offer approximately 8 hours of playback, while the charging case provides an additional 20 hours, totaling up to 28 hours of use. This is quite competitive for the price range and should easily cover several days of commuting or workouts without needing to recharge. The included 25.4cm USB-C charging cable ensures compatibility with modern charging standards. IPX4 water resistance means the earbuds can handle sweat during exercise and light rain, though they are not suitable for submersion. **Controls and Microphone** A built-in microphone enables hands-free calling, and the touch controls offer a comprehensive set of functions including play/pause, track skipping, volume adjustment, call answering/rejecting, and voice assistant activation. Having all these controls accessible directly from the earbuds adds significant convenience for daily use. **Overall Verdict** The Amazon Basics True Wireless Earbuds represent excellent value for budget-conscious consumers. While they lack premium features like active noise cancellation, they deliver all the core functionality most listeners need at a very accessible price point. They are an ideal choice for first-time wireless earbud buyers or anyone seeking a reliable backup pair for everyday use.
