Manuals of product MDR-EX31BN
Editorial note
The Sony MDR-EX31BN headphones stand out for their excellent sound quality, offering a frequency range of 20 to 20,000 Hz that ensures an immersive listening experience. Their noise-canceling feature is a major asset, allowing for full concentration on music or calls without distraction. Additionally, their impressive standby time, reaching up to 100 hours, reduces the need for frequent recharges. However, some drawbacks may affect the user experience. The 7.5 hours of battery life during use may be insufficient for heavy users, requiring frequent recharges during long listening sessions. Furthermore, the Bluetooth 3.0+HS technology, while functional, is relatively old and may limit compatibility with recent devices. The lack of USB connectivity and a 2.5 mm connector may also restrict connection and charging options. Overall, the value for money of the Sony MDR-EX31BN is satisfactory, especially due to their audio features and noise cancellation. However, the limitations in connectivity and the in-ear design, which may not suit all users after prolonged use, should be taken into account. These headphones are well-suited for daily use, offering comfort and sound immersion, but users should be aware of the minor constraints mentioned.Score details
