I am so happy I finally found this Wonderboom model.I had a great Bose 360 portable speaker that was ruined from being left outside too long.That model is no longer in production – and it took me over a month to find a speaker comparable to what I had.I ordered and returned 4 portable speakers before landing on the Megaboom 4 – – and after an hour of testing a wide range of songs I couldn’t be happier.What makes this speaker so great is the quality and variety of its sound. It sounds great on its own, but the app has an EQ slider with several presents and a custom setting to find the right levels to your taste. (EX – I found the preset for close quarters to work best for jamming to songs in my kitchen.)It’s a bit larger (and heavier) than I was expecting, but still fairly easy to throw into your luggage.And very much worth every penny when you compare against smaller and cheaper 360 speakers that are under £100. The ones I tried all had terrible, unbalanced sound in comparison.So in my opinion the Megaboom 4 is worth every penny!

First of all I’m not an audiophile just a music lover and as a music lover I can tell you this thing is great. I bought this to replace my UE Boom 2 which I also loved but I love bass so I decided to go for this. I waited for prime day and got this at a discount which was a bonus.The sound is very loud, it’s rich and for its size packs some bass. It’s so good I use it outside when having a barbecue. For a music lover like me who likes to listen to music whilst cooking, drawing, in the shower, this thing is great you can take it around with you. It’s not too big and not too heavy making it very portable.Overall the Megaboom 3 is great, the battery life is very good, lasting around 20 hours. I love it’s sleek and simple design and think it looks quite nice and stylish. It’s got excellent build quality and even though it’s not built like it’s competitor JBL speaker its still quite robust and durable.Whilst the Megaboom 3 is great, there are a few things that would’ve make this bluetooth speaker absolutely perfect for me. For one I wish they had left the mic/speaker phone function that was on the UE boom 2, it was quite handy being able to take a call and talk on the bluetooth speaker. They removed the audio jack so now the only way to connect to the speaker is via bluetooth. Finally it would’ve been great if the charging cable was usb type c. However in spite of all this, it’s still 5 stars from me, it’s competitively priced and an excellent product for what it is. I highly recommend it. Hope this was helpful.

Superb sound including outstanding base impact

I owned the original megaboom speaker and had enjoyed it for many year before the battery wouldn’t last anymore, after some brief research I decided to stick with what I knew and just upgraded to the megaboom 3. I have been delighted with the product I have received. A few problems with the original megaboom I had have been fixed with the introduction of a button to pause and skip songs and the charger port being moved from the bottom face to side so it can stand properly while charging.The sound quality of the speaker is excellent with lows and highs being the focus, the mid range is still excellent but certainly takes more of a back seat making instruments and beats stand out compared to vocals. The speaker gets incredibly loud whilst maintaining its clarity making it excellent for outdoor activities as well as indoor.Where this speaker really shines is it’s duribillity, it’s water proof and rugged enough to be dropped multiple times without any non-superficial damage and it’s battery means you can listen for hours making it perfect for barbecues and I imagine pool partys.I am extremely happy with this purchase and would recommend to anyone looking for an all purpose portable Bluetooth speaker.

This speaker sound is excellent!It’s clear, with lots of bass if you want (EQ in the phone app) and loud enough for a medium sized garden.It’s also built like a tank. Fells sturdy and reliable with quality materials used on all parts that you can see or touch.Due to this speaker is a bit heavy and quite large but still portable enough if you have a backpack. So far, with moderate use the battery lasted for 4 days and it’s still on 40%. Charging is also quite quick. My 25W multi charger can get it to 50% charge in about an hour.My only criticism it about how they advertise it for Alexa integration.This item does not support Alexa and push to talk anymore. This functionality was removed by Logitech (manufacturer) some time ago although it’s till advertised as Alexa device.Currently it can only work with Alexa as a Bluetooth speaker which is not what I wanted.But decided to keep it anyway as even without Alexa support the sound and build quality is still worth the money.

For the price the sound quality is excellent! Easy to use and to pair. Shame about having to use an app to setup an EQ. The main shortcoming is that it is Micro USB and not USB C.

Brilliant nice and loud worth the money not to big or small and waterproof

If your budget is less than £200, get this. Packs a punch way above it’s price, you won’t be disappointed. Easy to set up, with a customisable equaliser.

Un buen altavoz con un diseño simple y con una ridícula demanda de espacio sobre la mesa.
Me ha sorprendido gratamente su sonido, especialmente porque conserva los efectos estereofónicos de la música a pesar de ser un tubo vertical, además de por su claridad general y por la potencia de los graves en un tamaño y un peso tan contenidos (aunque no se puede comparar al del Homepod, por ejemplo, pero no decepcionan aún así). La mínima superficie de apoyo para mi era clave frente a otros altavoces que han de situarse horizontalmente ocupando 4 o 5 veces más espacio. La malla exterior, además de muy bonita en color (no sabía por cual decidirme), diría que es la misma que utiliza logitech en uno de sus teclados folio para el iPad, que habiéndolo tenido durante varios años puedo decir que es excelente y resiste los roces y el desgaste general como ninguna otra, sin generar pelusa, y esta parece exactamente la misma, como digo. Lo que no es malla es una especie de plástico rígido con cierta textura algo gomosa que se siente muy bien hecho. La configuración es muy sencilla y la aplicación está al día, además ofrece unos pocos modos de ecualización conservadores en cuanto a ajustes pero efectivos. Los botones responden bien. La autonomía parece ser la prometida, aunque aún no lo he llevado al límite. El volumen es adecuado diría para todo tipo de usos y se desenvuelve sin distorsión al máximo volumen. La carga es rápida, lástima que no incluya conector usb-c porque a estas alturas tener que estar lidiando con cables micro usb es un pequeño lastre, pero se pueden obtener bases de carga inalámbricas con conexión usb-c fácilmente. Señalar que según el manual la batería es extraíble y sustituible (se requiere destornillador, además supongo de sustitución del sello hermético) lo que para mí es un punto muy a favor y puede usarse mientras se carga tanto con carga crítica como completamente cargado. La base inalámbrica nuevamente parece interesante para evitar estar tocando la tapa del conector y garantizar un sellado más duradero contra el agua. Tiene una opción bastante útil a través de la app para que a pesar de estar apagado, y haciendo un mínimo consumo de energía, pueda encenderse desde la misma sin necesidad de tocar ningún botón, siempre que esté dentro del radio del bluetooth. Funciona perfectamente con iOS así que no transmite los sonidos y efectos sonoros del sistema, solo la música, lo que es de agradecer. Me ha encantado.

Ottimo prodotto, perfetto sia per casa che da portare in giro
Prima di acquistare questo prodotto ho letto decine di recensioni sia di utenti di Think Assemble che da siti esterni. La prima caratteristica, per me fondamentale, era che si potesse portare il prodotto senza il rischio di rovinarlo. Rispetto ad altre marche tipo il Jbl Flip 4 (dove alcuni siti dicono che è resistente anche alla polvere ma IPX7 vuol dire che lo è solo per l’acqua), questo prodotto ha una marcia in più perché è classificato IP67, quindi totalmente impermeabile (addirittura se dovesse finire in acqua galleggerebbe), e resistente alla polvere (perfetto per essere portato in spiaggia senza farsi troppi problemi). Questo è anche il motivo che mi ha portato a non acquistare i prodotti della Bose, in quanto il prodotto sarebbe confinato alle mura domestiche. Inoltre, rispetto ad altri prodotti, ha un’autonomia enorme (dichiarata 20 ore). Questa caratteristica non è stata ancora da me testata ma ho visto numerosi test che confermano la durata della batteria quantomeno sulle 15 ore. Questo a differenza del Sony SRS-XB21 che avevo adocchiato all’inizio ma con una durata di batteria effettiva che in molti hanno dichiarato su circa 2 ore (a volume massimo), e sinceramente portarmi il prodotto con il pensiero che non possa arrivare a fine giornata non era tra le caratteristiche che cercavo in un dispositivo portatile. Poi c’è anche da aggiungere che nel caso del Megaboom 3 difficilmente si dovrà mettere il volume al massimo (a meno che non si stia dando una festa) quindi la batteria non si consuma in fretta come altri dispositivi più piccoli e che quindi hanno necessità di “sforzarsi” di più per ricreare lo stesso volume.Passando alla connettività, il Bluetooth si collega immediatamente e dicono che prenda anche fino a 45 metri (non ne vedrei neanche la necessità) ma la connettività è stata giudicata da tutti ottima e su questo non ho fino al momento di che lamentarmi. Inoltre, è disponibile una app di Ultimate Ears che permette di regolare l’equalizzazione (una cosa davvero molto bella), oltre che regolare il volume, collegare tra loro più altoparlanti UE (in quel caso sarebbe davvero una discoteca), oppure un’altra feature davvero interessante dove è possibile collegare più dispositivi tramite Bluetooth al Megaboom e ognuno potrà inserire la propria canzone in playlist. Il gestore dell’app potrà poi spostare la coda delle canzoni per farle suonare secondo il proprio gusto, e ognuno dei vari amici potrà mandare la propria canzone (davvero cool, ci si sente quasi dei deejay). E’ poi presente il famoso magic botton dove è possibile, senza dover usare il cellulare, mettere in pausa e far ripartire canzoni oppure far passare alla canzone successiva (alcuni dicevano che non funzionava con Spotify ma io l’ho provato e funziona perfettamente anche il magic button, evidentemente hanno aggiornato il software).Per quanto riguarda il suono, i bassi sono potenti e bilanciati, gli alti cristallini e anche i medi pieni. Ho provato vari generi (rock, acustica, voice, jazz) e mi è sempre piaciuto il sound. Il Megaboom viene inoltre fornito con un un cavo e un alimentatore per la ricarica veloce (già testato, si carica in circa 90 minuti). Il peso del dispositivo è poco meno di 1 kg, certo non proprio leggerissimo ma messo dentro uno zaino non dà nessun fastidio. In definitiva lo considero un ottimo prodotto, fedele a quanto descritto. Acquisto consigliato.
