ULT Field 3 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, Rustproof, and Shockproof with Enhanced Bass, 24 Hour Battery and Shoulder Strap (SRSULT30B), Black

Still after bought 1st time used heard sound quality was good.

The sound on the speaker is absolutely amazing. The app for the speaker however needs a lot of work. The sound was so good I immediately bought a second one the day I got the first one so that I could utilize the "party connect" feature which allows you to connect up to 100 of these. The instructions on how to do it are as clear as mud. I've been able to get the speakers to connect two times, every time you turn on the speaker if you're going to connect a second speaker you have to go through the process each time. It took me about 25 minutes the first time in about 18 minutes the second time. The key is to only connect one speaker to your phone or tablet via Bluetooth, then hit the connect button on the first speaker, then turn on the second speaker without connecting it to Bluetooth hit the connect button on the second speaker. I had to go through the process several times including deleting the app removing the connection from my iPad and starting over. If you're only going to get one of these speakers I can tell you it's absolutely worth it the sound is amazing especially for its size. I bought this for when I travel with my iPad to have better sound quality playing movies and it does not disappoint. It gets about 12 hours of battery time if you're using the sound enhancing ULT, otherwise you can get up to 25 hours which is not even advertised for the device if you turn off ULT, I will say though the sound quality drops dramatically by turning off ULT. The build quality seems really nice, it feels like a solid piece of equipment that won't fall apart in your hands. The only complaint I have is the connection of multiple speakers.

Excelente producto a buen precio

Ces enceintes sont plus petites et plus légères que ce que j'aurais cru et c'est absolument parfait. J'en ai acheté 2 pour avoir une paire stéréo et la qualité sonore est formidable. J'ai testé avec du rock, du jazz et du classique et tous les styles sonnent à merveille, avec de belles basses bien définies. La connection Bluetooth avec mon iPhone et mon iPad fonctionne sans faille. Je n'ai pas pu tester au volume maximal car les voisins auraient porté plainte, mais ces enceintes sont vraiment puissantes. La façon dont s'attache la courroie de transport est inventive et géniale. Je suis très satisfait de mon choix.

Battery life is good, looks are ok, sound quality is good, easy to use
