Google Nest Audio Review

Audio Quality: the Main Advantage

The Nest Audio's clearest advantage over the Amazon Echo 4th Gen is audio quality.

The difference is audible within 30 seconds of side-by-side comparison.

Nest Audio specifications: 75mm woofer + 19mm tweeter, 75W Class D amplifier.

Echo 4th Gen: 3-inch woofer + dual tweeters, 75W amp (same claimed wattage but different driver configuration).

Google Assistant Advantage

Google Assistant excels at information retrieval.

Alexa excels at smart home control.

Alexa Routines are more flexible and have more triggers (time, device state, location, sensor input).

Alexa has more third-party skills.

Google Ecosystem Integration

For Android users who use Google services: Google Calendar: "Hey Google, what's on my calendar tomorrow?" returns calendar events correctly and can add events by voice.

Google Maps: "Hey Google, navigate to Home Depot" pushes navigation to your Android phone.

Gmail: "Hey Google, read my latest email" reads your inbox.

Privacy note: this requires giving Google Assistant access to your Gmail, which some users find too much.

Smart Home Hub Comparison

The Amazon Echo 4th Gen includes a built-in Zigbee hub, it can directly control Zigbee devices (most Philips Hue bulbs, IKEA Tradfri, Amazon Zigbee devices) without a separate hub.

The Nest Audio has no Zigbee hub.

To control Zigbee devices: you need a Nest Hub, Nest Hub Max, or a Google Home-compatible Zigbee hub (Samsung SmartThings hub, Philips Hue Bridge).

For users building a Zigbee-based smart home: the Echo 4th Gen's built-in Zigbee hub is a meaningful cost advantage.
