Seven alarms, escalating, and one of them can be your own music
Up to 7 individual escalating volume alarms; Wake to one of 8 buzzer options, any of your 100 station presets, or USB thumb drive.
The best alarm handling on this shelf, and each element earns its place.
Seven means a different time for each day of the week, set once — rather than resetting one alarm every Friday night.
Escalating volume is the right design: a gentle start that rises, instead of a jolt.
And waking to a USB drive is unusual — a specific piece of music, rather than whatever a station happens to be broadcasting at six in the morning.
For comparison: the Ocean WR-393 and WR-336M publish dual alarms, the WR-03M alarms by station, FM or tone, the WR-860 an alarm clock, the WR-18 an auto-off timer alone.
And thirty backlight settings, which is the bedside detail
30 daytime and nighttime back-light settings; Large blue or red clock selection; 12 or 24-hour clock.
Separate day and night brightness is what a bedroom actually needs, and thirty steps is unusually fine-grained — most radios offer three or four.
Blue or red is a real choice too. Red light disturbs dark adaptation least, which is why instrument panels and darkrooms use it.
The Ocean WR-860 and WR-18 both publish a display that can go “completely off”, which is the other answer to the same problem.
No microphone, stated — and voice control anyway
Even control your Mondo Alto by any Google Assistant enabled device in your home or office (for your privacy the Mondo Alto does not have a microphone).
The chain is: you speak to an existing Google speaker or your phone, and that device instructs the radio over the network.
Two consequences. Practically, voice control is not self-contained — you need a Google Assistant device somewhere in the house. And on privacy, a bedside device with no microphone cannot record a bedroom.
That is a legitimate thing to care about and a rare thing for a manufacturer to advertise. Nothing else on this shelf makes a statement either way.
Chromecast, multi-room, and the longest app list after the Grace Link
Chromecast means any Chromecast-enabled app on a phone, tablet or computer can send to it — and the device then fetches the stream itself, so the phone is only a remote, its battery is not drained and a call does not interrupt.
That is the divide on this shelf: the six Ocean Digital radios have Bluetooth and UPnP only, where the phone does the work.
Multi-room grouping works both with other Altos and with “any Chromecast enabled device” — so it is not locked to Grace hardware.
The built-in apps list runs to iHeartRadio, NPR, SiriusXM, Amazon Music and Prime and Unlimited, Spotify Connect, Pandora, Podcast, Sleep Sounds, Calm Radio, Shoutcast and Live365 — second in length only to the Grace Link’s. The SiriusXM caveat is properly attached: “subscription sold separately by SiriusXM.”
And AM and HD radio stations appear in the count alongside FM and internet, which no Ocean listing mentions.
A five band equalizer, and three ways to control it
Five bands rather than presets. The Grace Link publishes the same; every Ocean radio publishes “EQ sound modes”, which are fixed curves chosen by the manufacturer.
Front panel, included IR remote, or free apps — three routes, and on a bedside device the front panel is the one that matters at two in the morning.
The Ethernet arrangement is the weak point
Optional USB to Ethernet dongle for wired RJ45 ethernet connection (sold separately).
So there is no Ethernet socket: a USB port is pressed into service with an adapter you buy.
Against the shelf: the Grace Link at $179.99 publishes an “RJ45 jack and built in dual band Wi-Fi”; the Ocean WR-03M at $99.99 publishes “Wi-Fi or LAN”; the Ocean WR-50 at $179.99 publishes “wired Ethernet (RJ45)” with WPS.
All three cost less and have the socket.
Whether it matters depends on your Wi-Fi. For internet radio the bandwidth is trivial, so a wire buys reliability rather than speed — and it matters most where the signal is weak or the 2.4 GHz band is crowded. If your Wi-Fi is solid, the dongle is a non-issue.
What is not published
No speaker specification. No driver size, no power, no count — on a radio with speakers at $327.85. No radio on this shelf publishes one.
No outputs at all. No line out, no optical, no headphone jack — so this cannot feed an amplifier, where the Grace Link publishes “analog and pure digital outputs” and the Ocean WR-50 publishes four.
No analog input, which the Grace Link has and uses to send a turntable out over the network, and which the Ocean WR-860 has as an aux in.
No Bluetooth transmit. The Grace Link can send to headphones; this receives only.
No resolution figure, where the Grace Link publishes 24 bit / 192 kHz.
A hundred presets, where five Ocean Digital radios publish 150 — and four of those offer web browser management to organize them, which no Grace listing mentions.
No Wi-Fi band or standard.
2,404 g and 159 × 142 × 257 mm are published — and at 257 mm this is the tallest cabinet here, which on a bedside table is worth measuring.
