Addon C10

excellent sound, very balanced; excellent product; very happy with it

The speaker is great, but I ordered two by mistake and ask that one be refunded but still haven’t received a refund

Super-simple to set up and fantastic sound quality. Very pure sound, rich details and clarity. If only the app offered more options, particularly to play your own music…

This is the same review as the Drumfire since I use them together as a system..

I purchased 2 Drumfire units as well as a C10 and C3. There were three primary reasons I went with Audio Pro. The reviews on sound quality, the flexibility of being able to use airplay as well as other sources, and the multi-room capability and the ability to use the Drumfire’s as a left and right speaker. Unfortunately, they hit only one of the marks which is sound quality. What they don’t tell you up front is that you cannot use airplay and multi-room at the same time. Airplay will only work with a single speaker.

I watch allot of concerts that have video. These units do not work well as there is a noticeable sound delay between the audio and video. They do mention this in the manual, but if I had known audio delay was a feature I would not have purchased them. So, I am just using them as powered speakers now. I have my own DAC and hardwiring so the audio sync’s up with the TV.

I have all the same issues as others with the app. Its over-simplified and really doesn’t tell you what’s going on with the speaker especially when its telling you its playing but its not. It took me a while to figure out how its Wifi connection was working. It only uses your wifi to issue commands, but as far as its back-end streaming to other speakers if you are using multi-room it still appears to build its own network which (after sniffing it with a network analyzer) uses channel 1 all the time, so if you are in an area with heavy 2.4ghz usage on that channel the sound will be choppy. Again, after hardwiring it and changing them to just powered speakers, the performance is better.

There is also an issue with the C10 where it randomly shuts itself off even when there is sound actively going through it. I have to go back and turn it on constantly, which is very annoying. I will open a trouble ticket for this.

In summary, the sound quality once its setup and working is really nice. However, other than using them as powered speakers and basic bluetooth, I find all of the streaming technology worthless.

Sounds great, but not the “one” for me.

This is a great speaker; I know because I’ve heard it live at my friend’s house. Unfortunately, I ordered it before Christmas and Audio Pro didn’t ship it for over a week, so I cancelled my order to go look and buy it elsewhere. A few days later, after confirming my cancellation, they shipped me the order anyway and charged me for the speaker. I contacted them right away and, recognizing their mistake, they told me they would refund the order and send me a return label. No problem! However, it’s now been over two months, I’ve reminded them repeatedly, and they still haven’t sent a return label or sent me a refund. I have this speaker sitting, unopened, under my desk, and I may never get my money back. Probably among worst customer service I’ve ever encountered.

I have been enjoying it everyday since I got it 3 weeks ago, I am listening to it as a standalone. First I was debating between the C5 and C10, I am so glad that I went for the C10, just an inch or 2 bigger but double of the power. This is truly a high fidelity speaker, sounds incredible in such a small box, it produces all layers of sound clearly, especially the mid bass, I am so impressed!
I must say the AudioPro’s app is not that great, it losses its connection when it idles, I have to unplugged and replugged to establish the connection. I subscribed Deezer Hifi so I use Deezer app on iphone and desktop. Deezer app has a built-in equalizer for iphone only which makes this fantastic speaker sounds even greater as long as you have it connect to 2.4ghz network via audiopro app.
Overall I am very happy with the Addon C10, very well made and esthetically awesome!

Sound quality is nowhere near as good as expected
