Sonos Premium Personal Entertainment Set with Arc Ultra

Sonos Premium Personal Entertainment Set with Arc Ultra 

The Sonos Premium Personal Entertainment Set with Arc Ultra delivers a true “best of both worlds” setup: cinematic, room-filling Dolby Atmos home theater when you want to share, and premium personal listening when you don’t. At the center is Arc Ultra, a flagship smart soundbar built for ultra-precise spatial audio, crystal-clear dialogue, and deep, controlled bass—then Sub 4 takes low-end impact to the next level with distortion-reducing, force-canceling design. Add two Era 300 speakers to create an enveloping surround experience with dedicated spatial performance for music and movies, plus effortless multiroom streaming through the Sonos app. When it’s time to go private, Sonos Ace headphones let you immerse yourself with Active Noise Cancellation, lossless audio options, and TV Audio Swap from the soundbar—so you can keep the impact without waking the house.

Does this set create true surround sound for movies and TV?

Yes. Arc Ultra handles front/height effects while the two Era 300 speakers can function as surround channels, and Sub 4 adds deep bass for a full home theater experience.

Can I listen privately without turning the TV up?

Yes. Sonos Ace supports TV Audio Swap, letting you move TV audio from a compatible Sonos soundbar to one or two Ace headphones for private listening.

Do I need a special TV connection to get the best audio formats?

For the widest support (including formats that require it), an HDMI eARC connection is recommended and is required for certain high-bandwidth formats. Arc Ultra also supports HDMI ARC, and optical can be used with an adapter (sold separately).

Is WiFi required to use the system?

For setup, control, and streaming features, yes—each product is designed to work with the Sonos app and an internet-connected WiFi network. Some products also support Bluetooth for direct playback.

Can I use voice control with this setup?

Yes. Arc Ultra and Era 300 work with Sonos Voice Control and Amazon Alexa (service availability varies by region and language). Each has a mic switch to disable microphone power.

How strong is the bass with Sub 4—and will it distort at high volume?

Sub 4 reaches as low as 25 Hz and uses dual inward-facing woofers for a force-canceling effect that helps reduce distortion, keeping bass clean and impactful.

Can I connect a wired source to Era 300?

Yes. Era 300 has USB-C and supports line-in using a Sonos Line-In Adapter plus a 3.5 mm auxiliary cable (accessories sold separately)
