Nothing is ever perfect, but this isn't far off
It's true - nothing is ever going to be completely perfect. How could it be? If it was possible, I'd have chosen 4.5 stars. As it is, I had to choose five, because four feels unfair. That's because this little speaker, wrapped in its sleek, understated and unapologetically solid shell, does a good job of being almost perfect. We got off to a bad start. I don't know what the problem was. Maybe it needed a run in. Perhaps I placed it in a bad spot, or I sat too close. Whatever, when I fired it up and hit play on Bonobo's Break Apart, something sounded slightly off. The bass was a bit flat, the highs too airy and the mids didn't punch like I know they should. Not to be deterred, I shifted things around and switched (some might say unfairly) to Aphex Twin's Ageispolis. There's a bass line that never sounds flat. And it didn't. It didn't sound great either. But that's a tough tune for a lot of speakers, so it's hard to expect this little unit to cope at such a young age. A few more tunes and a couple of positional shifts later and things started to pick up. Maybe it was just weary from the journey. Or perhaps it needed to flush itself though with some soundwaves. Whatever the reason, Metronomy's Trouble is currently purring softly through the grills. The bass is firm and full. The highs clear and pronounced. And those mids are popping with a delicious punch. As others have said, the app isn't great. But then, it doesn't get in the way. The speaker isn’t particularly portable (if, by portable you mean you can wang it in a bag and lug it around all day). But the leather handle holds firm and you can move it from room to room as you go about your day. The short version of this is, the speakers sound sublime and the whole thing looks and feels like it's been designed and built with love. And for me, that's just about perfect.

Brilliant small room and portable speakers
Streaming high-res and enjoying clear sound in a small room. has never been easier with this stylish and well-built unit. It's not Hi-Fi, but you are getting better than these trendy JBLs and other tube-like speakers. You can also get a second one to run them in stereo if you wish and even connect a sub, so the upgrade path is perfect. The battery lasts long enough for a fun picnic in the park and more.

Fairly good but still a bit dissapointing
Wanted to initially purchase the bo portable speaker, but was misslead by a review to this one. I think it's pretty good, but it's just not great for many small annoying reasons. It doesn't work with my macbook through Bluetooth (haven't checked over WiFi yet). The sound is fairly good, but it's a significant downgrade from a bunch of cheap speakers with a cheap amplifier. I guess portability should make up for it, but looking at it straight it's just not something you'd want to take with you because despite small size it's bulky and heavy and the battery lasts for barely over an hour. Carriable around the house, but no further. Slightly bent upwards with legs sticking out which makes it awkward to place on a bed, for instance. Doesn't have a standby mode, so when you want to put it to work, you need to do it from your phone and from the speaker itself, which defeats the purpose of having a wireless speaker to begin with. Doesn't work with chrome cast if you want to direct your sound wirelessly from projector or TV. 4 buttons for presets, why would you put them on the speaker itself is beyond my understanding but I guess that's more of a preference. It seems to have lots of features at first sight, and it delivers but there's just no flow to them. The experience of using it has been plain annoying. It's really something you need to use the instructions for, not particularly intuitive. On the bright side, works flawlessly with Spotify over WiFi, build quality is pretty good. 1 month in, it's just not something I'd use on a daily basis. If you've got time for research and wait for a discount, you'd easily find something worthier for the money.

Amazing sound and all round great quality
I have used this speaker pretty much every day for over a year now after having had another couple of different makes previously that I didn't like, and for the money and size the audio quality of this speaker is simply amazing! It's not far off a proper hifi if used in a room which isn't too big. I also love that it can be taken round to other rooms, etc as it has a battery which lasts for a decent amount of time. The build quality is great. My only small gripe with it is that the I wish the buttons would be a little bit more protruding so they are more tactile and easier to "find". In my opinion there are too many touch screens in our lives these days and too few proper knobs and buttons so while the Audio Pro has proper buttons they are super-flat and not as satisfying to use as they could have been. Audio Pro: perhaps an idea for your next incarnation of this great speaker.

Not Impressed
The unit (I Know) held inside a beautiful sound experience, but after waiting patiently for 2.5 hour for it to charge. I spent another 3 hours going through the process of connecting it to Wi-fi, when really I just wanted to pair it by blue tooth ( it wouldn't let me) . It refused to operate as a blue tooth speaker and remained stuck on Wi-Fi mode and still did not allow my phone to play music through it. If ever I am offered a free Audiopro speaker, I will only take it if I'm paid to. NOT IMPRESSED.

I'm really a fan of portable music and not to mention speakers that you can take anywhere. I've always looked for the mix between good sound and battery life and it seems I've found it. With this equipment, I already have the T3 version which is truly a delight. But this unit seems impressive to me. Possibly the battery doesn't last long enough for a 12-hour session, but the sound it has is spectacular. It doesn't have the bass that a Bose speaker will have, but this portable Hi-Fi speaker has a very balanced sound between high, mid, and low frequencies. Something to keep in mind is that it's a Hi-Fi speaker, it's not just any speaker, that means that one has to balance or equalize to one's taste, which is why the speaker doesn't come pre-equalized. Highly recommended to people who are bored of listening to music with exaggerated bass equalization and prefer a more balanced sound. The network functions are good, not the best... but they do their job. This brand is really worth it. Always

L'objet en lui même est qualitatif, belle finition avec un revêtement plastifié légèrement granuleux qui évite de prendre les traces de doigts. Poignée en cuir véritable, bandeau de commande alu, commandes ergonomiques avec leds blanches pour identifier la source en cours, le niveau de batterie sur 3 positions, la touche mémoire activé si utilisé. Partie arrière métallique solidement visée; sous l'enceinte une trappe accessible pour éventuellement changer la batterie. L'enceinte reste compacte mais d'une belle taille (un peu plus encombrante qu'une Sony xb33 ou marchall stockwell.) L'objet est design et épuré pour s'intégrer partout. Portable en intérieur ou partir en vacances, mais pas mettre dans le sac à dos... Avec 2kg. Le son est vraiment bon, les garves puissantes et percutantes a 90/100 Hz, le reglage sortie usine avec l'equalisation à +3 sur 5 donne un côté très boomy... Pas vulgaire mais bien marqué. En ramenant le réglage a 0 ou -1 l'équilibre est très bien maîtrisé. Les mediums et les voix sont bien mises en avant et les aigus fins sans acidité. Au final un son bien rond avec une belle ampleur qui soit occuper la pièce. La puissance sonore restitué est impressionnante eu égard au volume de l'enceinte et le niveau restitué est élevé a 3/4 du volume max. Les 25W RMS qui semblent dans la moyenne, sans plus, sont bien exploités... j'avais un peu peur avant d'acheter que la puissance soir juste, mais largement rassuré. En comparaison au niveau rendu, cette enceinte délivre autant qu'une JBL charge 5 de puissance supérieure et dans la grande majorité des cas le réglage volume a 50/60% du max suffit. Pas constaté de distorsion a fort volume. J'ai vu bcp de commentaire sur l'application audio pro avec des notes peu flatteuse...De mon côté (pourtant exigeant) dans sa dernière version cette app fonctionne parfaitement et offre de belles possibilités, bien mieux que la concurrence. Déjà tout les services de streaming sont intégrés (personnellement QBuz, Amazon music, Spotify répondent bien), le plus c'est l'intégration de TuneIn ou Vtuner pour diffuser le radio depuis l'app audio pro sans avoir à installer en propre les applications. Un onglet permet de régler toutes les enceintes pour le multiroom et de régler tout les paramètres de l'enceinte comme les graves/aigus, le fonctionnement en mode stéréo ou simplement HP droit ou gauche dans une installation avec deux enceintes, fonction réveil ou timer, changer le nom de l'enceinte, mise à jour du firmware. La possibilité de preaffecter les 4 raccourcis sur les stations radio ou playlist est vraiment au top. L'application est sobre sur fond noir sans fioritures, le seul petit bémol c'est qu'elle a du mal à afficher certaines métadonnées dont la pochette pour le contenu stoker dans l'appareil; curieux alors que ça marche parfaitement pour toutes les sources en streaming... Pas bien grave il y a la possibilité de diffuser la musique depuis une application tierce réseau comme bubbleUpNP... Car une fois connecté au réseau wifi cette enceinte est reconnu DLNA. Point d'attention pour la première connexion ( ce n'est pas indiqué dans la notice), comme cette enceinte ne fonctionne que sur la bande wifi 2,4Ghz il faut penser à passer son équipement téléphone/tablette sur la bande 2,4Ghz et surtout désactiver l'option automatique qui permet aux appareils de sélectionner la meilleure bande wifi...sinon ce dernier va se reconnecter sur une bande 5Ghz et l'association avec l'enceinte ne marche pas...j'ai cherché 10mn au départ... Après pas de problème de décrochage ou de coupure, c'est très stable. Enfin l'autonomie est très acceptable et plutôt bonne avec en moyenne plus de 12 heures, la promesse des 15heures d'écoute a volume 50% est tenue. Très homogène et pourvu du WiFi, bien mieux que tous les modèles d'enceintes aux noms commercial Bo...JB...Mar... So... On aurait juste apprécié du bluetooth 5.0 plutot que 4.0 mais en intérieur le wifi est incomparable et permet la diffusion de fichier FLAC Hi-Res sans broncher ! Très recommandable !

My main priority is sound quality. I bought this because of a strong review on WhatHiFi and I’m happy beyond my expectations! The sound is true-toned, crisply timed, and musically balanced, giving a satisfying, authentic rendition of anything I’ve played on it. Really fabulous musical quality for the money. IMO the volume is sufficient to fill a large room or a good sized outdoor area. The unit is handy to move around and Bluetooth Spotify was working in seconds once the initial charge was completed.

Ho già in casa un impianto Hi End, e cercavo un ottimo speaker bluetooth per ascoltare musica dal cellulare, non mi interessavano le funzionalità wifi. Avevo puntato il T3, con la superba qualità audio dei prodotti Audiopro e una batteria con una durata incredibile. Poi ho trovato questo C3 in offerta ad un prezzo più basso del T3 e l'ho acquistato, seppure dispiaciuto di aver perso metà della durata della batteria (15h invece di 30h del T3). Beh, da quando è entrato in casa questo smart speaker mi ha cambiato la quotidianità. Me lo porto ovunque, in bagno, in cucina, in camera da letto, in terrazzo. E ho rivalutato molto le funzionalità wifi a cui inizialmente non ero interessato, praticamente ho ritrovato il gusto di ascoltare la radio in casa. Le qualità audio sono eccezionali, è incredibile sentir uscire un suono del genere da un oggetto così piccolo. Merito dell'amplificazione in classe D, di un accordo reflex posteriore e di un ottimo setup generale. Manca solo un'immagine ampia e tridimensionale, impossibile da ottenere con queste dimensioni e senza elaborazioni artificiali. La timbrica del C3 infatti è assolutamente corretta e godibile. In definitiva a parità di dimensioni non credo esista uno smart speaker migliore di questo, considerando qualità costruttiva, qualità audio, durata batteria, funzionalità bluetooth e wifi. Inoltre in versione bianco è un bellissimo oggetto di arredamento, ha superato anche il test "moglie"! Se proprio devo trovare un punto debole direi che, solo quando funziona a batteria, è un po' lento ad accendersi e a collegarsi alla rete wifi, in tutto circa una ventina di secondi, presumibilmente poiché per salvaguardare la batteria quando è spento non rimane in standby ma si spegne del tutto. E all'accensione deve riattivare il modulo wifi, cercare la rete ecc. Questo non succede quando è collegato alla rete elettrica, poiché da spento rimane in standby. Poi, certo, l'app forse non è delle migliori, ma se non si è interessati alle funzioni multiroom fa onestamente il suo lavoro, con alcune funzioni interessanti come la funzione sleep (suona fino alle ore...) o la funzione sveglia (suona dalle ore...). E comunque è un software, si potrà sempre sviluppare in futuro. L'hardware è un capolavoro. In definitiva prendetelo, non ve ne pentirete!
