Editorial note

The Sennheiser RS 135 is an audio headset that stands out for its sound quality and user comfort. Thanks to its binaural design and closed acoustic system, it offers an immersive audio experience with a sensitivity of 106 dB, ideal for music enthusiasts. The 20-hour continuous playback time is a major advantage, allowing for long listening sessions without interruption. Additionally, the hybrid nickel-metal rechargeable battery ensures durable and economical performance. However, the product has some drawbacks. The lack of RF connectivity limits wireless connection options, which may restrict compatibility with certain devices. Furthermore, the absence of a plug adapter may require additional purchases to ensure optimal use. Although its weight of 230 g is generally comfortable, some users may find it a bit heavy during prolonged use. Finally, the lack of a microphone reduces the possibilities for use in calls or voice recordings. Overall, the Sennheiser RS 135 is an excellent choice for those seeking a quality audio experience, but it is important to consider its limitations in terms of connectivity and versatility.
