Sonos One SL (White), The powerful microphone-free speaker for music and more

Product Information

To some extent all electronics will have some level of hiss. From my chair I cannot evaluate if your hiss level is abnormal or not. I tend to be abnormally sensitive to this sort of noise (‘buzz’ -- get it) and I’m not annoyed by the SONOS hiss levels. Hiss is usually masked by normal room noises, but if your rooms are very quiet and you sit very close to a speaker, you are more likely to notice the hiss. Unfortunately, once you are sensitized to the hiss, it never goes away and becomes a “ The Princess and the Pea” drama. The hiss is emitted from the speaker drivers, both woofers and tweeters. There is a potential for another type of noise that is generated by the power supply. I don’t consider this noise as being normal. It is not emitted by the speakers and typically emits from the rear of the unit when there is a problem. Normally this noise is above the frequency range of humans, but if, due to a defect the frequency slips down, it may be audible to some listeners. Since high frequency hearing capability varies from person to person and the high frequency limit of humans diminishes with age, there can be some arguments between listeners over this “obvious” noise. Early ultrasonic alarm systems used in schools operated at a frequency that was easily heard by kids, but not audible to adults. There would be running arguments between the distressed kids and the adults about this noise. (‘What noise!!’) When I was younger you’d observe me take a step into a retail store, then abruptly turn and leave. I was repelled by their “ultrasonic” alarm system that had not been turned OFF during business hours. For sound quality, the Sonos Five actually isn't just good value, it's absolutely great value. But it's a case of different strokes for different folks; if Bluetooth streaming is important to you and you own an Android phone, you should look elsewhere. The hissing/white noise starts as soon as audio starts playing. It continues when you pause whatever is playing for 15 seconds (every time as I have timed it). This hissing/white noise remains at the same level no matter the level of volume from the speakers. The quieter the audio, the more you notice it when audio is playing.

A soft self-generated hissing noise is so common on active speakers that some manufacturers publish the level of self-generated noise for their products. I am a current Sonos product user. I have two Five’s in stereo. I’ve previously had a 1st Gen Beam, two One SL’s and a 1st Gen Play:5.

For yet another year, the Sonos multi-room system remains the best all-rounder.” ’What Hi-Fi?’ 2023 award-winner. The Sonos wireless sound system is simply one of the best-sounding, most reliable and flexible there is. With the latest Sonos components, you don't even require a BRIDGE or BOOST, as they are capable of linking via your home Wi-Fi system. For the very best results, though, linking one component to an Ethernet connection will allow you to take advantage of the famous Sonos 'Mesh' system.

In traditional Sonos style, the Five is not interested in a shy, retiring sound – it's here to bring the bass and make you feel it, and we're not complaining. However (and we've said this before) it's important to note that we like it more if you can use TruePlay tuning, and not everyone is granted that privilege. I am aware active/powered speakers hiss. I’ve had the pleasure of owning other makes of active speakers. That's not to say it's bass-heavy overall though. Listen to Fontaines D.C.'s Skinty Fia and you'll hear a low-end that, while impactful and unwavering, never bloats or muddies other musical passages such as accordions, drum riffs, angered vocals and keys.

I also have a separated hi-fi of high end equipment and I get a small amount of hiss/white noise from the speakers but nowhere as bad as Sonos.
