The Sonos Era 300 has emerged as a top contender in the wireless speaker space, particularly for users who prioritize a well-rounded, high-fidelity audio experience with immersive spatial sound capabilities.Key Features and DesignSpatial Audio Support: The Era 300 is optimized for spatial audio, supporting Dolby Atmos, which creates a 3D sound experience. It has a unique hourglass shape that’s not just aesthetic but also functional, helping disperse sound in multiple directions for an immersive effect.Speaker Configuration:Inside, it packs a six-driver array, including four tweeters and two woofers, allowing it to project sound not just horizontally but also upward, enhancing the depth and fullness of the listening experience. The sound quality is especially good with music produced in Dolby Atmos, which maximizes its spatial capabilities.Connectivity Options:Sonos has added versatility to the Era 300 with Bluetooth 5.0 and Wi-Fi 6 connectivity, a welcome improvement over previous Sonos speakers that were limited to Wi-Fi. This makes it easier to connect various devices and use the speaker in different scenarios.Voice Assistant Compatibility:The Era 300 supports Alexa and Sonos Voice Control (but not Google Assistant), which makes it convenient for hands-free operation. The voice pickup works well, even in louder environments, due to its built-in far-field microphones.Sustainability and Design Updates:The Era 300’s design is more eco-friendly, using recycled materials and being partially disassemblable, which supports easier repairability. The physical buttons on top, including a handy volume slider, make it user-friendly and a bit more tactile compared to the fully touch-controlled previous models.Sound PerformanceThe Era 300 shines in terms of audio fidelity, especially for its size. Its soundstage is wide and detailed, with impressive clarity in highs, balanced mids, and deep bass that doesn’t overwhelm. The spatial audio support takes tracks that are mixed in Dolby Atmos to a new level, giving a “live performance” feel with a strong sense of directionality and space.Music Playback:The Era 300 performs well across genres, but it’s especially suited to high-quality recordings that benefit from its spatial audio capabilities.Home Theater:Paired with a Sonos Arc or Beam Gen 2 soundbar, it enhances surround sound setups, creating an immersive, cinema-like experience at home.Vocals and Instruments:Vocals come through with strong presence, while instruments maintain separation and clarity, preventing any one part of the mix from sounding muddy or overpowered.Pros:Exceptional spatial audio for immersive, room-filling sound.Versatile connectivity with Wi-Fi, Bluetooth, and optional line-in via USB-C.Sleek, modern design that fits well in various interiors.Enhanced Sonos ecosystem compatibility, making it ideal for multi-room audio setups.Improved sustainability with recycled materials and repair-friendly design.Cons:High price point may make it a less accessible option for casual listeners.Lacks Google Assistant support, which limits voice assistant options.Dolby Atmos audio quality is heavily dependent on compatible sources, so standard stereo tracks may not make full use of its spatial features.

I have previously purchased other small bluetooth speakers that were ok but not impressive with sound quality or had loud they go, I know a few people who have some of the smaller Sonos speakers and they said how impressed they were so I decided that I would take advantage of the Black Friday deals and get the Sonos Era 300.The speaker arrived in an impressive box which makes you feel that you have bought something that it going to be excellent quality. I decided to put the speaker in my kitchen, it was very easy to set up using the app and to link my various music accounts/podcasts/BBC Sounds Etc.The sound quality is impressive especially with Apple spatial music, the clarity of each individual instrument is excellent (low and high volume), I also wanted a speaker where the volume would be high for when we are having a bit of a party, its definitely fits the bill though I don’t think we would be able to have it on full volume, 75% is very loud.The speaker though purchased in the sale is still quite a bit of money but I think it is worth it, and if I decided that I had some spare cash and wanted to get another speaker for another room I wood go for the Sones Era 300 again.

This is an astonishing speaker. Due to a house move I had to downsize my hi-fi. Sold my amp, speakers etc.After reading the reviews for the best wireless speaker I plumped for the Sonos ERA300.After opening the box it took me less than 10 minutes to be listening to music. I was amazed at the depth, and clarity of this speaker. Vocals are reproduced effortlessly and acoustic guitar is a delight to listen to. I’m rediscovering music I hadn’t played for a long time.It connected to my iPhone playing Spotify immediately.My only criticism is that you have to pay £20 for a lead to connect a none Bluetooth external device ( in my case a Brennan JB7). Personally I think this should be included in the package.Apart from that I have no negative points. I just love it’s simplicity and sound quality.Highly recommended.

The quality of this Sonos product is amazing, it’s Stylish and will fit in anywhere. Even blend in when needed. It’s so easy to set up, Most people should be up and running within 10 minutes or so.I’ve tested many types of music, I’m a massive music lover, and I’ve had many speakers over the years. This one is just different. The left and the right stereo separation, is the best separation that I’ve heard from one standalone speaker. The highs are balanced without becoming Harsh even at higher listening volumes, The base is well defined and will Satisfy most people. For me, it was the mid range, vocals were sharp and Never became Hazley or unfocused. Overall, the sound was a Pleasure to listen too.Connectivity is so freeing with this speaker. WiFi, which allows features like Apple AirPlay, Alexa and Sonos App control. There is also a USB type C Connector at the back of the speaker, This can be use to connect a turn table or a ethernet Cable. Keep in mind that these adapters are so separately. I would totally recommend this speaker, You probably won’t regret it!Note I received a used item, when I purchased a new. Think Assemble has been okay about this. And they did do a Partial refund. It wasn’t a big amount. But I’m busy, so I just took it as there was nothing wrong with my unit. I would like to have been maybe treated a bit better but This experience doesn’t affect my review on this speaker.

Brilliant Sound
It is inexpensive kit but the Spatial Audio is Outstanding. I use it a a single room filling music for when I have guest and personally at home. Works brilliantly – without the sub. My room is about 1000 sqf
