The best in the class
What a marvelous radio this is! I am a media maven; I listen to public radio every day. For years I got by with a Sangean portable but it used up batteries like they were potato chips. So I bought Panasonic rechargeable batteries for it, but found that their voltage wasn't quite right and therefore the radio quality suffered. I figured it was time to buy a radio that was inherently rechargeable. So I read the reviews and selected the DX-286 from Qodosen. When it arrived I was surprised to see its credit-card size. The good folks at Qodosen shoehorned every technical capability into this tiny radio, but it's way over-engineered and became more of an irritant than a convenience; how do you set this thing? How do you turn off the alarm? And the kicker was that the sound was tinny and unsatisfying. I tried living with this for months and finally decided that I owed it to myself to find something easier to use and better quality. A few days ago my PowerByte arrived. Immediately I could tell that this was a substantial product. It is heavy! It has large speakers. But there is tremendous value in this radio. First, it is extremely logical and easy to set up and use. When you turn it on for the first time, it automatically scans and stores all available FM stations. And designating a particular station as a favorite (there are 9 spots for this) is as easy as doing so in a car. Everything about the design is simple. There is a nice, old-fashioned dial for power and volume. The buttons are at the top and have simple functions. The EQ button gives you a choice of three settings - one balanced, one for speech (which lessens the bass) and one for maximum bass. The speakers in this radio are superb. They sound good at any volume, but if you want to crank it up for, say, a party, you could not find anything better than this. The unit is rechargeable through USB. It takes about 3 hours of recharging to run for 20 hours...although you may want to just leave it plugged in. Unlike some other units, this one can run with the charging cable plugged in. I have not yet tried it with Bluetooth, and I have no need of plugging in SD cards or a USB drive. For me, the PowerByte serves its purpose as a superb portable, rechargeable FM radio which, based on my many years of experience with audio, sounds just right. Highly recommended.

Son vraiment excellent !
Belle fabrication, utilisation facile, radio, lecteur de carte micro sd, clé USB, bluetooth,entrée aux , bref c'est ultra complet ! Capte bien les stations fm. Dispose de 3 égaliseurs (préréglés) . Écran avec indication de l'état de charge ( très utile ! ) Mais là où c'est vraiment parfait, c'est la qualité sonore ! Les basses vraiment top !! J'ai essayé pas mal d'enceinte portable mais celle ci est sans aucun doute la plus complète et avec la qualité sonore au rendez vous. Un Sans faute !! Juste faire attention car elle n'est pas étanche ! Autonomie après essai, 3 journée de 9h sur chantier à faible volume reste une barre de batterie, donc plus que raisonnable ( 29h environ à faible volume) !! Vraiment top 👍👍👍

Gutes Radio, Guter Player, Guter Sound.
Meine Erwartungen als langjähriger Avantree Nutzer (der kleine kompakte, ideal für Reisen und schon 2 x verschenkt) sind erfüllt. Was nicht ganz perfekt ist: Digitale Lautstärke Einstellung im unteren Bereich zu grob. Konkret: USB Player Volume von 0 auf 1 schon zu laut bei einigen Stücken. Da würde ich mir eine nichtlineare feinere Auflösung wünschen. ------- After 1 Month: Hahaa I click to give compliments for the Avantree POWERBYTE and there appears Underwear I bought - very funny but does not matter. Both Products are good, and the Sound excellent (not of the pants :) I have 3 Avantree 850 already and now the bigger but still very mobile PowerByte. When the Bass started I got a Wow Feeling and a stupid Grin in my Face. The Sound of the 850 is already very good for its Size, and the PB keeps that Ratio Bass per Kilogram :) I am very happy with that Radio ( it is much more of course, SD, USB, BT ...)

Brilliant radio/speaker. Buy!
I just received this and I'm really impressed! Banana for scale ;) For context, I consider myself an amateur audiophile, having accumulated some of the more high-end audio devices (including a pair of Sony WH-1000XM5 headphones, a Bose SoundLink Flex Bluetooth speaker, and a Sony home theater system with a dedicated subwoofer). Enough with the bragging and back to this new addition to my collection. I wanted something with a radio for when I get tired of my music collection. Naturally, I spent an ungodly amount of time searching and I'm really glad I finally went with this. The sound quality, first and foremost, is amazing. Almost indistinguishable from my Bose, although not quite (this is high praise). It comes with three equalizer options: a balanced mode, a voice mode (with suppressed bass), and a bass-boost mode (as you can imagine, this mode literally shakes my table). I mostly use the balanced mode as I appreciate the full audio range - the highs, mids and lows - all of which are rendered excellently by this ELEGANT little beast. Besides sound quality, the FM reception is top notch. Without having to extend the antenna, I receive up to 10 clear stations. It is nice that you can assign favorite stations to quickdial numbers. Bluetooth connect with quick and breezy, and the music play is awesome. There are options to play music from an SD card, USB flash drive, or AUX cable, but I don't see myself needing those. This is becoming a bit of a ramble, but I hope this review makes you buy this device. You will not regret it!
