## Description

desertcart.com: PRUNUS J-777 Pocket Radios Portable AM FM Small Personal Radio | with Best Reception, AAA Battery Operated Transistor Radio with Headphone & Speaker for Walk/Jogging/Camping : Electronics

Review: Very compact; performs better than many bigger/costlier radios - The Prunus DE-333 is among the smallest pocket radios you can get, with a width of only 2 inches and a height of 3-1/2 inches. And, it only costs about what you'd pay for a fast food combo meal. But it delivers excellent reception, especially on FM, along with good sound and a DSP (digital signal processing) chip that makes it easy to achieve perfect tuning even of weaker and more distant stations. After receiving this radio I opened up the battery compartment and put in two AAA batteries. The radio happened already to be turned on, and it came to life with an FM station from about 60 mi away. Finding it surprising that I received this station so easily, I tried a couple of hard-to-receive stations as a test, and this little radio pulled in both of them. Admittedly you do have to tune very slowly to get weaker stations that are right between stronger ones because the tuning thumbwheel is small and it's easy to skim right past them. But if you're patient and move your finger slowly, those weak "in between" stations are there. AM reception isn't quite as good as FM, which you expect because the internal AM antenna in a radio this size has to be tiny. Still, you do get local and regional stations strongly, and at night many distant ones come in, too. This radio has a DSP chip that makes it easier to tune precisely. Unlike a radio with conventional circuitry, a DSP radio will usually move directly to the center of the signal when you reach a station. So, there's rarely a need to do any sort of fine-tuning. Once you can hear the station, it's perfectly tuned in. The sound is crisp and clear. News and talk shows sound very good. Even music sounds surprisingly decent given the size of this radio and its speaker. The audio gets quite loud, as well - and you can turn it up full blast without distortion. So, there's plenty of audio power to let you listen to this radio outdoors or in environments such as factories or other noisy workplaces where you might have to turn it up to hear it over background noise. Along with the radio you get a nice protective carrying bag with a drawstring closure. It's big enough to carry a couple of extra AAA batteries alongside the radio itself. The carrying bag adds an extra touch of class to a well-assembled, impressively compact radio that already distinguishes itself with competent reception and pleasant sound.
Review: By far the best radio for sports, news, talk radio regardless of price - Got this radio when the first one I bought (same radio) started fading out at random times. Turns out the radio station was moving its transmitter which created the problem. Now I have two of these radios both of which work perfectly. I tried a lot of much more expensive radios ($50 to $90) and none of them performed well. Decided to try cheap. The $12.99 radios perform the best by far. The radio holds the station with never an adjustment - much better than the expensive ones. Also, they are very small and lightweight so they can easily be carried in a shirt pocket while doing yard work or moved from the coffee table to the patio table. Great for sports, news, or talk radio. Clear, distinct sound for those purposes. By far the best I have found. Compared to other radios, the two required AAA batteries have an acceptable life.

We hope our answer will help you.

Best Regards
PRUNUS Service

**Q: Does the radio send a true two-channel stereo signal - one channel to the left earpiece and one channel to the right earpiece?**
A: No stereo on this radio but still very nice speaker in this lovely Prunus J-777 in white color.

**Q: Who manufactures Prunus Degen transistor radios?**
A: www.degen.com.cn.  is from on the back of the radio.  This is from their website in China. "Founded in 1995 , Shenzhen Dejin Electronics Co., Ltd. is a state-level high-tech private enterprise."  Hope that helps.

**Q: Should i embrace the brand name, prunus?**
A: Yes, go with your inner PRUNE.... When you do, people will know you as a PRUNUS Owner.
It is a name that in English would not be chosen by a US manufacturer. But the
unit is: good looking, packaging so nice, it looks more expensive than it is and
it comes with a custom draw-string bag. I keep it in my cargo pocket when at work.
It is made well and sounds good. Buy it, you'll like it. Hope that gets you over PRUNUS
name.
