I will be very careful in my review (after a failed evaluation that I don't understand how I was deceived and I did it, and I corrected it much later, i.e. after the holiday).
The machine is ok in terms of weight (neither heavy nor light to feel fake), it is not large in size (except for the depth), it has an amazing button layout (with a good feel) to make your life easier, it has 20 radio presets selectable with the next-previous buttons but also 3 additional buttons for direct selection of favorite stations (smart and convenient), it also has next-previous folder for mp3 files (on CD or stick) and a sleep timer. It also has auxiliary input and headphone output.
In terms of radio, the band search is a bit slow but since it has so many presets it doesn't matter. The reception is ok and generally stable, even if there is some slight "interference" in stations that it cannot capture very well (perhaps justified), but this is probably more of a logical thing than a problem.
It does not have a bass boost button (which it needs) or any equalizer presets to achieve something more and different with the sound. As it plays... it plays.
It has really good volume if the signal is not low (the 2x2 watts are not bad at all for such a device).
Now, in terms of sound, I don't know what exists and what plays in the market at these prices (around 70 euros), but one would expect something more. It is relatively decent, but it is not a miniature of full sound with bass and weight.
If you listen with headphones, you will see that the sound is excessively bass-heavy, something that does not come out at all on the speakers.
In general, it is a bit tight and somewhat dry, as if harmonics are missing. One would expect more musicality from SONY (generally and especially at 70 euros) and you suspect the bass more than it actually exists (e.g. the Panasonic RF-2400 radio for 26 euros, without space to help the speaker, clearly sounds more bass-heavy and much fuller). Surely, from a portable device, you do not expect a particularly good bass, but the sound, as it is, highlights its lack. In general, you constantly have the feeling that the sound is somewhat small, thin, and a little empty.
The simpler the music, the better it sounds, the more complex things become, the harder it gets and it may sound somewhat confused and it is not pleasant to increase the volume too much.
In a simple phrase, it should have better speakers, which would also be desirable to go lower and fill more. These are not enough.
If it had a remote control, the situation would be saved somehow, because it generally does the job fully, being very user-friendly.
However, the sound, which (apart from the bass and volume issues) does not have any particular melodiousness and sweetness to gently caress your ears and in which you cannot make any intervention, does not match the rest of the machine and based on that, it should be considerably cheaper.
Perhaps many people can get used to its sound and forgive some of the issues it has, but it remains its Achilles' heel because otherwise the machine is really very good.
23/7/19 After so many months that I have it, I can say that maybe I had slightly excessive expectations from a portable device. What I wrote is true, of course, but maybe at this price, things are not so bad. Especially now that I realized that if you don't listen to it "face to face" it sounds much better without highlighting its weaknesses and it feels more melodic. It could and should have something more in terms of sound (i.e. to be fuller and to have some settings for improvement) but if you have it somewhere and you generally listen to it from different angles without putting your ear directly in front of it, it does the job (always having a sense of bright, delicate, and volume-less sound). I would ultimately give it 3.5 stars but that's about it. However, for someone who wants a bit of bass and full sound, it's not at all. S. D.
