Haven’t heard the neighbors since!
I wanted some outdoor speakers to enjoy music on my patio and maybe even pool movie nights. I didn’t want to have to constantly be recharging speakers. I am so glad I found these! They came as a pair, I took them out of the box,plugged them in, used the remote and was immediately able to sync tomy phone. They are so easy to use even my husband can do it! (He hates reading instructions) I like the ease of hookup and sync, and the sound is not bad at all. We listen to primarily metal and rock and they are loud enough to drown out the neighbors! The gorgeous voice of David Draimen and the fierce growl of Corey Taylor both shine through loud and clear. The eq feature works really well for movies, justice sure it’s off during regular music play. The price was phenomenal and shipping was quick. Great buy.

Awesome speakers and great customer service!
These speakers look nice and sound incredible! The pairing capability works very well between speakers, with simple instructions that made setup a breeze.One of the things I was initially concerned with was the range of the remote. These speakers are mounted up under my garage eaves (about 8 feet off the ground), but the remote reaches easily. The manual is very well laid out and I have had no problems connecting the speakers to my phone and other Bluetooth sources. Great sound quality for the money, and they are LOUD at maximum volume, with no distortion!I ordered some additional speakers to add on to the two I already have, but the Bluetooth names between the sets are different, making them incompatible. I sent an email to their support and received a reply the next day, offering to replace the older speakers with a brand new set for free! I had read other reviews before I purchased these and the great customer service was always a selling point for me. It’s something that you hope you never have to use, but I can confirm that the stories are true: they really stand behind their product.These speakers are one of the best purchases I’ve ever made!

Make sure you don’t have the older ones.
Great speakers, good sound, easy connection with caveats below, but a few things to note:1. Inwa doesn’t seem to respond to customer service requests.2. The older firmware versions have a square ended remote, and broadcast on bluetooth as their model number “mz-xxx”.3. The newer firmware ones have the rounded remote and broadcast as “sync speaker”.4. If you buy multiple, and they have different firmware with different broadcast names, THEY WILL NOT SYNC. If they have the same version, they sync very we, and very quickly. There’s no delay betwwwn speakwra or odd behaviors that I found.5. There is a pretty long delay from the source to the speakers. No problem for audio. Not great for using with alexa speaker groups or outdoor projector.6. If you get the older firmware versions, expect them to blow out your windows every time you reconnect to them. They reset to 100% volume kn every connection. The new version doesn’t do this.7. The easy, no involvement connection between speakers is noce, but also a flaw. Because these connect automatically to each other, you cant have two sets doi f two sources. Thats sounds like no painless, but if you’re neighbor buys a set, you’re both going to have problems. It would be better if you could connect series of speakers, then lock the connection function.

Buy them NOW!
Ran to the review section to brag about this product. Long story short, I ordered something completely different than what I intended. Best mistake ever. Here’s why.First, it’s a great value for the money. Along the cheaper side for the wallet, you get WAY more than what you pay for.Next, The sound quality and volume is amazing. These speakers are SO loud on full volume. Perfect for outdoor spaces, garages, man caves, game rooms….you name it. I have had it bluetoothed to my phone, and my outdoor TV, which by the way, makes college football games SO much better than most set ups I’ve tried.Lastly, these speakers are pretty sleek in appearance, and very versatile in terms of connectivity. Both speakers require a power plug. One Speaker is the primary speaker that hooks up to bluetooth. If both speakers are plugged in, the secondary speaker will automatically connect to the primary, providing sound WHEREVER you want.These speakers were so good, 3 of my friends ran to AMAZON and bought them as soon so they experience the awesomeness. Do yourself a favor, buy them now

Good output
Bluetooth pairs easily. Can be turned up so the neighbors outside can hear my music. Would be great outside around the pool. I like that I don’t have to charge it; just plug in and play. I do also own and use the USB charge type of speaker but if I have power I use these, I’m very happy with them.
Kindle Customer –
Sound ok but would recommend buying something different.
These speakers sound great but on the remote remote control does not work. Would I purchase from this company again?â¦Probably not.

Muy satisfecho con la compra: gran sonido y resistencia al exteriorLlevo ya un tiempo usando estos altavoces Inwa en mi terraza y no puedo estar más contento. La calidad de audio es sorprendentemente buena para su tamaño, con un sonido nÃtido y potente incluso en espacios abiertos. Además, han aguantado perfectamente las inclemencias del tiempo sin perder rendimiento ni mostrar desgaste. Una opción muy recomendable si buscas altavoces duraderos y de buen sonido para exteriores.Compre un segundo par sin lugar a dudas después de llevar usándolos un año (verano e invierno incluido)

Die Boxen kommen mit Haltern für die Montage und das Inbetriebnehmen ist kinderleicht.Aktuell habe ich 2 der Lautsprecher bei mir im Pavillion 5×3 Meter und es reicht vollkommen.Werde trotzdem nochmal 2 nehmen um den Klang dann aus allen 4 Ecken zu bekommen.Klangtechnisch, sind die Lautsprecher vollkommen in Ordnung.Laut genug sind sie auch, falls man mal eine laute Party feiern möchte.Jeder Lautsprecher benötigt allerdings seine eigene Steckdose, oder man nimmt eine Mehrfachsteckdose.Alles in allem, sind die Boxen für den Preis total gerechtfertigt und funktionieren Problemlos.Die Bluetooth Verbindung ist stabil und der Radius ist ausreichend GroÃ.Ich kann sie weiter empfehlen.GruÃSebastian
