Manuals of product Mu3
Editorial note
The KEF Mu3 earbuds stand out with their in-ear design, providing optimal sound immersion and prolonged comfort, ideal for long listening sessions. Their Bluetooth 5.0 wireless connectivity technology ensures a fast and stable connection, although the 10-meter range may be insufficient in crowded environments. The impressive 24-hour continuous audio playback allows for uninterrupted music enjoyment. However, it is worth noting that the 9-hour continuous playback time may seem limited for some users, especially if they do not often have the opportunity to recharge the charging case. The compact charging case with fast charging via USB Type-C makes daily use and transport easier. However, the silicone design of the ear tips may not suit all users, particularly those with allergies or sensitivities to certain materials. Finally, although the price of the KEF Mu3 is relatively high compared to other models on the market, which may deter budget-conscious buyers, the sound quality and features they offer make them an attractive choice for audiophiles and users seeking an immersive audio experience.Score details
