Rated 5 out of 5 by from The Infinity One ROCKS!!! I picked up my Infinity One a few weeks ago. I liked the way it looked, I like Infinity quality, and wanted to see/hear what it really good do. Listening to the system in the store does not do it justice for what it actually sounds like in your preferred environment. I'd like to start off, I have several other portable systems from other brands, but they do not compare to the Infinity One. I've even put then side by side, and the Infinity One outperforms each one. It sounds great in every application I have used it in: - Small room (12' x 12') - Large room (14' x 25') and 8 people talking/partying - Two car garage while working on cars - Outside on the deck - In an office as a speaker phone and as a VoIP/Internet Phone The Infinity One is versatile, easy to pair with any Bluetooth device, I have yet to completely drain the battery....and I've had it unplugged over 6-7 hours. It is good at low volumes and has volume to spare...it ROCKS!!! The bass response is great for its size. It is clear and free of distortion....and if you want a little better response out of it, place the Infinity one in a corner and let bass reflect work in your favor. Over all, this product is INCREDIBLE and has exceeded every expectation I have asked of it. It may be on the higher end (price wise) than the competitors with the same form, fit and function, but you get what you pay for, and the Infinity One is worth every penny. I highly recommend it and thinking I may need another one for my work office.

Rated 4 out of 5 by from Detailed Sound, Limited Bottom End My background is that I have had a lot of premium audio, and built my own loudspeakers. My first impression is that the sound was detailed and bright, with an enhanced airiness. I wasn't sure if I would like this enhanced sound, but I did not find it tiresome even after a four-hour listening session. The battery had no problem with volume on medium-high. Then I did a side-by-side against my Harmon Kardon Onyx 2. The Onxy sounds more true, more flat, with less you-are-there ambiance vs. the Infinity. The Onyx puts out slightly more sound level. I was leaning towards the Onyx when I played some Kid Rock. He likes to hear his bass go "boom!," and I remember that frequency being around 80 hz. Well, the Infinity was unable to produce it AT ALL. I thought maybe it was a limitation of volume, so I lowered the level and tried it again. Nothing. So, if you like an enhanced sound that makes music sound more alive, this speaker will not disappoint, and it will sound airy without creating listener fatigue. If you want any low bass, forget it.

Asked by: Chet
There is no Android application to remotely control the INFINITY ONE. For Volume, we recommend that you set the speaker to a decent level and simply adjust the volume of your Android device depending on your preference.

I've had my Infinity One for about 1 year now and the battery will no longer hold a charge for more than 5 minutes.  As a result, I have to keep it plugged into power all the time.  Any ideas?

Is there a software update for my infinity one portable Bluetooth speaker. The sound seems modulated at mid volume. If there is can I have the link

Asked by: Vincr
We have not rolled out any updates for the INFINITY ONE speakers to this date. If you feel that the audio is a little bit too soft or modulated, try using a different source(i.e Mobile device, media player, etc...)
