ZHIWHIS Portable Bluetooth Radio, FM AM Shortwave Radios with Sleep Timer and Preset Function, Rechargeable Digital Recorder, Stereo MP3 Player with Lyric Display, Support Micro SD Card and AUX

FINALLY! The firmware was fully corrected! Its a bit complex to operate it. But, it's an incredible device for the money! You can record your favorite Radio shows and has a very balanced tone with main speaker and woofer in the rear. The FM reception is not quite as sensitive as the earlier Retekless version, but the audio is clearer, a bit brighter. Im so happy, I just ordered another one.

This has some nice features for a low-end portable shortwave radio. Plusses include: - Bright easy to read display - Direct frequency entry - Flexible inputs for use as a computer/Bluetooth/MP3/radio speaker - Ability to record good quality sound from the air, the radio, Bluetooth or Aux input - Very strong sound - Play/Pause button that works both on music files and as a mute button on radio - Equalizer tone control (only works with recorded music, not radio) The radio is compact and convenient to recharge with the included USB cable. But while the display is bright and easy to read, the labels on the buttons are not. In anything less than bright lighting conditions, I can't read the buttons. The the tiny off white or orange labels don't provide strong contrast. You can see this in the last product photo that on my monitor is about the same size as the actual radio. It's professionally lit but the text on some of the labels is not sharp. It's much worse in indoor lighting. I've had many radios, and this the only one I can't read easily. While the sound from the radio speaker is quite good for something this small, the sound from earphones with radio is not. With a good pair of Apple ear buds, the bass disappears and an annoying high frequency hiss is substituted, something not seen in other radio models. I do not think that someone who intends to use headphones for radio will be satisfied with this product. I don't expect any serious shortwave listener will be relying on an inexpensive radio like this, but I should mention that the tuning is not all that selective, allowing clear reception of strong stations when tuned +/- 5 kHz (sometimes even 10 kHz) off frequency. Sensitivity is on par with other radios at this price point. It lacks an antenna jack. Sensitivity is fair, but not on par with something like a Tecsun PL-330. Also the shortwave coverage is limited to 4.75 to 21.85 MHz. The lack of a clock is a mystery and if you want an alarm, you're out of luck. This also means no time stamp on recorded files, but at this price point even radios with clocks don't timestamp recordings for some reason. I found some of the controls not intuitive. When listening to radio, tapping the volume up or down button actually switches between stored stations [This has been fixed with Firmware update 2.4]. Changing volume is click-hold -- but when listening to music you can just tap the buttons for volume. When entering a frequency, you complete the operation by pressing the Play/Pause button. I found that the left and right stereo channels are reversed when playing MP3 files, but correct for Bluetooth and FM. There are much better radios for more money, particularly for shortwave, but for FM plus a music player at this price point, the ZWS-603 is hard to beat. Update: I've had this radio for a year now. I never use it any more. Initially I took it with me largely because of the recording feature; I'd attach a cable to another radio that couldn't record and make recordings with with the ZHIWHIS. It's more convenient to record off the air with my phone rather than carrying an extra radio and a cable. If one has a better radio (I have several), there isn't much of a role for a lesser performing model. My review sounds more negative than I feel about the radio. It's strongest point is the speaker -- it's really good in a subcompact radio. That's what I think of first. This radio is also sold as model K-603 under the HanRongDa brand. Update 2: In 2024 a new version of this radio was introduced with a revised circuit board and firmware version 2.4. I bought the HanRongDa K-603 label. I don't know all the detailed changes but two things that stand out are the improved operation of the volume control and the USB-C charging port instead of USB Micro. The current product description (January 2026) still says USB Micro and the linked V2.4 manual say Micro, but I doubt that's accurate.

I’m really happy with this little guy! I ordered an extra battery so I wouldn’t have to worry about running out of juice, but I was pleased to find it came with 2 batteries. I’m losing my hearing and I used it for a regional convention, not only to hear better, but to help me focus. Compact, lightweight, just overall a great little transistor.

Bought this one over a different one because it had Bluetooth. Beware, you can’t connect Bluetooth headphones. It only works as a Bluetooth speaker. First of all it arrived a day late and I was going out of town. My friend had to get it out my mailbox and bring it to me. Only thing that works on this thing is the radio and it’s not great. Bought it to listen and record a radio station for a convention being broadcast over fm radio. You can see from the video that when I press record the radio goes out and it’s just this static, and that’s what it records. When I connect to Bluetooth and try to play music, it plays the same static. It records the same static when trying to record from the microphone as well. Tried restarting, charging fully, reformatting the brand new micro sd card and that didn’t help anything. Wish I would of ordered it early so I would of had time to return it and get a different one. I’ve seen other good reviews on this and maybe I got a lemon but I won’t be getting this one again. Lesson learned. This will be returned.

This radio is perfect for my need to listen to AM Radio but it has amazingly thoughtful features. I wanted a radio that could tune local AM stations with clean sound (no whistles, static, and hiss beyond what is normal for any AM broadcast of sports games or talk radio. Here are two lists of Features I wanted and the other of features I didn’t know I wanted but appreciate and will use. I wanted an AM Radio that could -- Receive especially local AM and also FM stations. The AM needed to be clean and clear without the whistle, hiss, garble,distortion and bad tuning, common on today’s AM radios. -- Record AM broadcasts direct off the air -- Display Digital frequency -- Allowed direct input of frequency for a station on real numeric keys -- Store more that 6 or 8 stations for AM and FM (it does 40 and 60) This radio does all of these. (It’s very rare for a radio to be able to record. This one does.) The recorded broadcasts were indistinguishable from live. (you need a cheap micro TF flash card.) I’m in Houston. The radio received all local AM stations Receiver sensitivity and selectivity were adequate for local stations and even managed to receive far away stations even WLS in Chicago after sunset. Sound quality was clear, without whistle, hiss and distortion. It worked like my AM radios from the 50’s & 60’s--something lost in most of radios today, even from SONY, etc. But I was amazed with other features which worked well -- a real surprise to find in a single package. 1. The LCD screen is very readable and nicely back lit 2. A button will turn on the back light for several seconds (on battery) 3. The radio will work even while being charged (I did not notice the interference mentioned) 4. The battery is li ion rechargeable and a common, standard size BL-5C and cheap to replace but INCLUDED. 5. Won’t need AA batteries to leak and ruin the entire radio. 6. Has headphones out jack (Stereo on FM) 7. Has auto seek to scan a band and store stations in memory 8. Can store any tuned station into any of 40 or 60 memories 9. Press tune up/down an extra second and it seeks to the next broadcasting station 10. Has selectivity enough to separate close together stations 11. Displays time counter during both record and playback. Can Fast Forward also. 12. Has single button mute 13. Can record live voice via built in microphone (Worked perfect, picked up the room) 14. Comes with soft protective case 15. Instructions are comprehensive and written in quite normal English, printed on quality paper. 16. Recorded files are named automatically and appear like any PC scrollable list of files The included USB cable allows charging from nearly any USB charger (I have plenty) and receives the very common mini-htmi charge connection like the ones on Android tablets and cell phones for a decade. The Antenna is quality but not needed in my experience for local broadcasts. At this time The “List Price” is $30 (but was discounted) and with all of these actually working features, that’s a miracle. Final word. I was impressed by the product's functional completeness. It even had a carry strap (already installed) and a little fob on the strap you insert into the back to partially stand up the radio! All of the above, I have personally verified. I tried the Short Wave band, out of curiosity, with no results—didn’t care and silly to expect otherwise. Amazing radio. Amazing combination of features. Amazing price. I’ll likely buy a spare because this is in a class by itself.
