What the maker puts in writing
- “Compact Internet radio: Handheld, lightweight, practical, and easy to use. Built-in rechargeable battery for power. Store your favorite stations up to 150 and access the top 5 stations with a touch of the 1-5 preset buttons”
- “Using the [Skytune Search] button is a breeze! Input the CALL letters or keywords of the station name to find the stations. User-friendly web browser control to manage/edit your favorites. Contact us if you can’t find your favorite station”
- “Ordinary FM Radio: In addition to Internet radio, this device also receives local FM stations”
- “Sleep & Dim buttons: You can turn off the display during bedtime and set the radio to auto-off for sleep”
- “It allows you to play audio from a Micro SD card and use it as a Bluetooth speaker. You can also play content from UPnP/DLNA-compatible network devices”
It is the only one here that moves
Handheld, 130 × 29 × 80 mm, 358 g, with a rechargeable battery.
Every other product on this shelf is AC-powered and stays where you put it — and the Ocean WR-393 states “Mains Powered” in its own title, which is an unusual thing to publish and a useful one, since people buying a kitchen radio frequently assume otherwise.
So this is the one that goes to the backyard, the bathroom, the workshop. That is the entire argument for it, and nothing else on the shelf competes.
What the listing does not publish is how long it lasts. No capacity, no runtime, no charging time — on a product sold as portable. At 358 g the cell is small, and an internet radio runs continuous Wi-Fi reception plus amplification, which is a heavier load than a Bluetooth speaker. Expect hours rather than a day.
The Dim button helps: a color display is a significant share of the draw on a device this size.
Access the top 5 stations with a touch of the 1-5 preset buttons.
Physical buttons, not a favorites menu — and on this shelf the counts are: 5 here and on the WR-393, 4 on the WR-336M, 3 on the WR-860, a front dial on the WR-50, and the two Grace units relying on their remotes and apps.
The difference is a single press against navigating a list, which on a radio you use every morning is most of the experience.
Up to 150 stored favorites sits behind the five buttons, and the Skytune Search button finds stations “by call letters or keywords” — call letters being how American stations are actually identified.
And the browser management is what makes 150 usable
User-friendly web browser control to manage/edit your favorites.
Editing a hundred and fifty stations on a handheld with five buttons would be intolerable. Open a page on a laptop on the same network and it takes minutes.
All six Ocean Digital radios here offer a version of this, and two go further: the WR-50 and WR-393 let you “add custom station stream URLs”.
That is the feature that makes the directory count irrelevant. Grace claims 100,000 stations and Ocean Digital’s Skytune “thousands” to 30,000 — but a device that accepts a URL you paste in has no practical limit, and the listing’s own “Contact us if you can’t find your favorite station” is the honest version of the same point.
Micro SD and UPnP, which cover local music
Micro SD playback is unusual — only this and the WR-860 on this shelf offer it, where four products take USB. On a portable radio a card is the better choice: nothing protrudes to be knocked off.
UPnP/DLNA streams from a PC or NAS on your network, and it does so without the phone involved — which is the one respect in which these radios are not dependent on Bluetooth.
What is not published
No network casting. No Chromecast, no AirPlay 2, no Spotify Connect. Bluetooth means the phone decodes and transmits: it stays in range, its battery drains, a call interrupts. Five products here avoid that — both Grace units, the WiiM Mini, the iEAST Olio.
No outputs. No line out, no optical, no headphone jack stated — so this cannot be assumed to feed an amplifier. The WR-336M at $89.99 publishes a 3.5 mm headphone out; the WR-50 publishes four outputs.
No resolution. The WiiM Mini and iEAST Olio publish 24 bit / 192 kHz; no Ocean Digital radio publishes any figure.
No speaker specification — size, power or driver count — on a product whose speaker is the whole point.
No battery figure, as above.
