Sharp Osaka: Two-minute review
If you’re the person that loves to have tech to match your personal aesthetic, the Sharp Osaka isn’t really the one for you. What it is, though, is a great value solution for anyone who simply wants to listen to the radio from seemingly any location.
Smaller than my desk calendar, the Sharp Osaka is easily grabbed with one small hand and slips into my coat pocket well enough, too.
As with all DAB radios, the only bulky part is its extendable aerial arm which you can easily hide away when not in use. The Sharp Osaka’s battery life comes in at about 15 hours which isn’t above average for such radios but will serve you well for most of your active day. Charging via USB-C means you’re unlikely to need to pack an extra cable any time you go away, too.
Costing £70 – that’s about $90 in the US or AU$143 in Australia, where available – when first released in September 2024, the Sharp Osaka is already discounted at time of writing, bringing it down to an even more affordable £50 ($65 in the US and AU$102). That’s a good price for a DAB radio of this standard and it also doubles up as a basic Bluetooth speaker.
Its controls are more intuitive than its convoluted manual suggests, leading you to mostly enjoying the Sharp Osaka without much hassle. One of the best DAB radios? Maybe not, but still a simple solution to your radio listening needs.
Sharp Osaka review: Price and release date
- Released September 2024
- Cost £70 / €90 (currently only available in the UK and Europe)
The Sharp Osaka DAB radio was released in the UK and Europe in September 2024. It costs £70 / €90 depending on your region (unfortunately, it’s not available in the US or Australia as it stands) so it’s affordable for a DAB radio.
We’ve already spotted some discounts emerging in the UK with the price more around the £50 mark.
That makes it one of the more affordable portable DAB radios around. It’s much cheaper than the stylish but premium Roberts Revival Petite 2 and also the ageing Sony XDR-P1 DAB radio. It’s slightly more expensive than the Groov-e Boston but that’s far from the right size for putting in your pocket.

Sharp Osaka review: Features
- DAB and FM radio, plus Bluetooth speaker
- 12-hour battery life
- 3.5mm headphone jack
The Sharp Osaka DAB radio has all the features you could need without offering up much in the way of surprises. At first glance, it looks like it’s only a DAB radio but it uses a technology it calls BestTune which combines FM, DAB, and DAB+ into a single station list to help you find the best option based on signal strength. I really liked this as it saved me switching between different modes while still gaining the best signal.
In all, the Sharp Osaka has a 120-station memory spread equally across BestTune, DAB and FM and, honestly, you probably won’t have to overthink this either. I simply turned it on and it figured things out for itself, quickly allowing me to find the station I wanted to listen to.
A tap of the source button also takes you to the Bluetooth side of things. Bluetooth 5.3 is in charge here so you won’t need to fret about any drop-out issues when pairing with your phone or tablet. I certainly didn’t have any issues switching between the two.
Sharp’s website in various regions differs between 15 and 12 hours of promised battery life, however I found the latter to be the rough sweet spot during use. As is often the way, volume can affect a lot here. The USB-C cable is perfect because on my travels I didn’t have to worry about packing an extra cable to recharge it.
On the side and next to the USB port is a 3.5mm headphone jack if you want to connect the Sharp Osaka DAB radio to the best wired headphones for some added privacy.
Other neat extras include an alarm function and a SlideShow tool which displays images from the radio station where available. In reality, I never found a station that offered this but I’m continuing my search in my own time as it sounds fun.
Features score: 4 / 5
Sharp Osaka review: Sound quality
- Mono speaker
- A little tinny
- Loud volume but some distortion
The Sharp Osaka is impressively loud, especially given its relative size. Though 10 is the average volume you’re likely to use, it goes all the way to a Spinal Tap-trouncing 30. It travels far, too. I cranked it up then walked a few rooms away and could still hear it.
That comes at a price with the audio quality not the best and offering some distortion but it’s fine for casual listening. I checked out Absolute 90s and found suitably old and nostalgic while listening to Blur’s Tender and The Rhythm of the Night by Corona. The latter lacks some excitement with the Sharp Osaka lacking crispness and spark, but the former translated reasonably well, never once leaving me waiting for that feeling to come.
This is the radio you’ll listen to while doing other things rather than indulging in your audiophile urges.
Sound quality: 3 / 5
Sharp Osaka review: Design
- Functional, lightweight design
- Simple-to-use buttons…
- … but not especially tactile
The Sharp Osaka gets right to the point with its design – it isn’t spectacular looking but nor will it confuse you. On the front left sits the mono speaker, with its controls and screen to the right. The 2-inch color display is simple but clear, other than when looking at it in bright light conditions.
Controls are also similarly easy to figure out although there’s no tactile quality to it which will be an issue for anyone with sight issues. That’s not uncommon with many popular DAB radios but it does mean my search for a more accessible DAB radio will have to continue.
When listening to the radio, you’ll need to pull out the antenna which is quite tightly clicked in at other times. On the side are ports for charging and headphones. There’s also a neat little key lock button which means no one can accidentally tap a button by mistake.
The Sharp Osaka is only available in a black/gray mix but it looks reasonably sleek.
Design score: 3 / 5
Sharp Osaka review: Value
- Inexpensive
- Ideal for a quick fix
- Cheaper than most
The Sharp Osaka was pretty cheap compared to the competition even before it went on sale (which seems to be commonplace now). Its primary competition for portability is something like the aforementioned Roberts Revival Petite 2 but it’s far cheaper than that. A closer rival could be the Pure Woodland but that’s less portable.
It might not be as adorable as that Roberts but the Sharp Osaka is far more affordable, which makes it tempting.
Value score: 5 / 5

Sharp Osaka review: Also consider
How I tested the Sharp Osaka
- Used the Sharp Osaka over two weeks
- Listened to DAB radio, and music via iPhone 14 Pro and Bluetooth
- Over 10 years’ experience testing audio equipment
The Sharp Osaka followed me around the house and the garden. I mostly used it in my home office but I also moved it to the kitchen while I cleaned and the living room while relaxing. On the rare days of good weather, it followed me outdoors for a little bit.
I used it exclusively via the rechargeable battery as it saved me finding a USB port to connect it to. I mostly listened to the radio but once in a while, I listened to some podcasts through my phone. This was typically via Spotify.
Otherwise, there was a lot of Absolute 90s, ranting at LBC, and relaxing with BBC Radio 5 Live.
