Which sounds better, the Sonos Roam or the Harman Kardon Go + Play?

The Go + Play. It has 100 W of power and a 2-channel setup, while the Roam is a small single-driver speaker. The Roam wins on portability, not on volume.

Which has better battery life?

The Roam, at up to 10 hours, against 8 hours for the Go + Play. Real-world results depend on volume.

Can I use the Roam for multi-room audio?

Yes. It joins a Sonos system over Wi-Fi. The Go + Play can only pair with a second Harman Kardon speaker through Wireless Dual Sound.

Does the Go + Play work with Alexa?

Only through a connected phone or tablet. The Roam has Alexa and Google Assistant built in and works over Wi-Fi without a phone.

Is the Roam bundle worth $149.99?

It is a fair price for a Wi-Fi smart speaker with a charger included. If you mainly want loud sound outdoors, the Go + Play gives you more for the money.

Can I charge my phone from either speaker?

Only the Go + Play. It has a USB port for charging phones and tablets. The Roam has no power output.
