Hi UB+ Team, I was amazed at the performance of the units I got and I have placed another contribution 154 and would like to know when you can dispatch it to me? I'm happy to waive the 14 day Indiegogo cooling off period to get it expedited as I intend to take it with my overseas soon? Thank you!
Whoa! Just received my speakers! Only had for maybe 10 minutes. Wow so much quality sound from such a small package !! The speaker exudes quality, packaging is first class. What a professional company, Really delivers on what they promise. Thank you UB! Gotta go now and listen and enjoy.......
Received it today! I took it out of the box, paired to it without issue and have been listening for an hour and still have 88%. It was shipped fully charged. Beautiful looking speaker but more importantly it sounds fabulous. I regret not getting two...
Hello, Thank you very much for the speakers. I am very impressed by the design and sound quality. However, I am missing one of the larger diameter tripod legs. I am backer number 72.Many thanks
These pair of S1 speakers look beautiful, paired perfectly, and sound exquisitely awesome on TWS via the app. Excellent job, guys!
Hi, I've been using your Eupho S1 circle speaker. It's a nice looking speaker.I mostly use it connected to my TV using the Aux input. On a regular basis it mutes with no sound. I have to turn up the volume on the TV, and sounds return. Using Bluetooth, the speaker is good.
