Manual of product 48821
Editorial note
The Bose 48821 stands out for its lightness and comfort, weighing only 12 g, making it an ideal choice for prolonged use. Its impressive standby time of 100 hours allows for use without frequent recharging, although the 4.5 hours of communication time may be insufficient for some users during extended trips. Wireless connectivity via Bluetooth is a major advantage, offering freedom of movement without the constraints of cables. However, the Mini-USB connector, while functional, may seem outdated to many, while the lack of a plug adapter could limit compatibility with certain devices. In terms of audio, the monophonic model may not suit everyone, especially those seeking an immersive stereo experience. Despite this, the modern design and included carrying case add a practical touch to the whole. In summary, the Bose 48821 offers good value for money, although it has some limitations, particularly in terms of communication time and connectivity. The well-thought-out features make it an interesting choice for users looking for practical and comfortable earbuds.Score details
