Gute Verarbeitung und Klang. Auch bei hoher Lautstärke durch 2 kissen guter Klang. Top.

Funciona muy bien, es bastante plano y se oye de manera nítida

Great pillow speaker, works as expected and you can hardly hear it once you take your head off the pillow, so won't disturb anyone else. A little larger than I expected but I can't feel it through my pillow.Sound quality is excellent with a good mix of base. I'm not sure why there are so many reviews saying that the volume is too low. I use it with an old MP3 player, and yes, the volume on that does have to be on nearly full, but the clarity is so much better than the cheaper flat round little speakers I have tried before - they were so tinny and the wire felt cheap and broke.There are three switches on the speaker, one seems to reduce the vocals to almost nothing (not sure why you'd want that) and I can't tell the difference between the other two, but I have used it for voice and music and it is really clear.

Basic analog audio system, works differently depending on pillow stuffing. Overall works well. Negative: power source is taken away, draining your battery if used throughout the night. …..…which then requires additional purchases to make it fully functional. Bluetooth capability would be much better.

Only as loud as your equipment can produce as not amplified or powered, but loud enough for me to hear my talking books through my pillow with my ear directly over it. It doesn't seem any quieter with it up the wrong way so I use it like that as the base is flat, whereas the top is curved and could be slightly uncomfortable through a thin pillow. Sound quality for speech is excellent.It is well built with tough, tangle free wire and a switch to ensure compatibility - I had one which refused to work with my google pixel phone, but no problems with this one at all. I thought this had gone wrong so was returning it, but it turned out to be a faulty converter to fit it to my phone which was not supplied by Roberts (annoying that some phones removed the 3.5mm socket). Fitted a new one and hey presto, perfect again!
