What the maker puts in writing
- “Connect via WiFi (2.4GHz) to access thousands of radio stations and podcasts worldwide through Skytune… Set you favorite region in Local Radio so that you can always access the internet radio station available in your local area with one click. Also supports standard FM reception with a telescopic antenna”
- “Equipped with the latest Bluetooth V5.3 technology… It also supports UPnP/DLNA… Features an external WiFi antenna socket for superior signal stability”
- “Features a large, clear 3.5-inch color screen that displays station logos, song artist/title, and a big clock. Designed for ease of use with dual navigation knobs and 5 dedicated preset keys”
- “Store up to 150 favorite stations… organize stations into custom categories (e.g., ‘Morning Mix,’ ‘My Jazz’). For power users, the radio supports web browser control via PC or smartphone to easily manage favorites, add custom URLs, and tune stations remotely”
- “Set two separate alarms with options to wake up to a Tone, My Favorite station, or FM Radio. Includes a Snooze function, a Sleep Timer (up to 180 mins)… and a dedicated Kitchen Timer”
Five preset keys and two knobs, which is the best control here
Dual navigation knobs and 5 dedicated preset keys on the front panel for one-touch access.
On a radio you use every morning, that is most of the experience. The counts across this shelf: 5 here and on the WR-18, 4 on the WR-336M, 3 on the WR-860, a single front dial on the WR-50, and the two Grace units relying on a remote and an app.
Two navigation knobs rather than one is the other half — typically one for browsing and one for volume, so neither is a mode of the other.
And the 3.5-inch color screen is the largest on the shelf — against 3.2 on the WR-03M, 2.4 on the WR-50, WR-336M and WR-860, and 2.8 on the Grace Link. It “displays station logos, song artist/title, and a big clock”, which on a kitchen radio seen from across the room is the right priority.
The external antenna connector, which nothing else here has
Features an external WiFi antenna socket for superior signal stability.
It matters because of the band. This radio is 2.4 GHz only, and 2.4 GHz is the crowded one — shared with every neighbor’s router, microwave ovens, cordless phones and Bluetooth itself. At the edge of coverage in a apartment building it can be close to unusable.
An external antenna can be raised, angled, or moved away from metal. And a radio in a kitchen is generally surrounded by exactly the metal that blocks it.
The WR-50 takes a similar approach with “external Wi-Fi and Bluetooth antennas”. The alternative is to remove the problem: the WR-03M, the WR-50 and the Grace Link all publish a wired Ethernet port.
But 2.4 gigahertz only, which three products here are not
Connect via WiFi (2.4GHz).
The band trade is well defined. 2.4 GHz travels further and penetrates walls better, but it is congested and slow. 5 GHz is faster and far less crowded, with shorter range.
For internet radio the bandwidth is irrelevant — a stream is a fraction of a megabit — so what matters is congestion, and that is where 2.4 GHz loses.
Dual-band on this shelf: the Grace Link at $179.99 (“built in dual band Wi-Fi”) and the iEAST Olio at $76.99 (“2.4GHz/5GHz”). And the Logitech Squeezebox at $397.34 is worse again, at 802.11g — a 2003 standard, 2.4 GHz alone.
Custom URLs, which make the station count beside the point
Web browser control via PC or smartphone to easily manage favorites, add custom URLs, and tune stations remotely.
Every internet radio depends on a directory, and the claimed numbers differ by a factor of three: Grace says 100,000, the WR-50 says over 30,000, this says “thousands”, all through Skytune for the Ocean models.
None of that tells you whether your station is listed.
With a custom URL you paste in the stream address yourself, and any station with a public stream works regardless of directory. Four Ocean radios here offer browser management; this and the WR-50 explicitly offer custom URLs.
The WR-18’s own line — “Contact us if you can’t find your favorite station” — is the honest admission of why the feature matters.
And 150 favorites in custom categories — “Morning Mix,” “My Jazz” — is what makes a list that size navigable. A flat hundred and fifty entries on a knob is not.
“Mains Powered” in the title, which is worth stating
An unusual thing to publish, and useful: people buying a kitchen or bedroom radio frequently assume a battery.
Only the WR-18 at $84.99 has one on this shelf — “built-in rechargeable battery” — and it is the only portable product here.
Bluetooth 5.3, dual alarms, and the timers
Bluetooth 5.3 is the newest version on this shelf, against 5.0 on the WR-50 and Grace Link and unversioned elsewhere. In speaker mode the phone decodes and transmits, so it must stay in range — later versions hold the link better at distance.
Dual alarms waking to tone, a favorite station, or FM, with snooze, a sleep timer to 180 minutes and a kitchen timer. Four Ocean radios here carry a kitchen timer, which is a sensible thing on a device that lives in a kitchen.
The Grace Alto at $327.85 goes further with seven alarms at escalating volume.
What is not published
No outputs at all. No line out, no optical, no headphone jack — so this cannot be assumed to feed an amplifier, and it is a self-contained Bluetooth speaker in that respect. The WR-03M at $99.99 publishes line-out and optical and calls itself “a pure tuner”; the WR-50 publishes four outputs.
No network casting. No Chromecast, no AirPlay 2, no Spotify Connect — so a streaming service reaches it only over Bluetooth, with the phone in the path. Both Grace units and the WiiM Mini and iEAST Olio avoid that.
No speaker specification — no driver size, no power — on a product sold partly as a Bluetooth speaker.
No resolution figure, where the WiiM Mini and iEAST publish 24 bit / 192 kHz.
No weight, and at 249 × 191 × 119 mm this is the second largest-footprint radio here after the WR-860.
