Let's begin by discussing some things we did not have in the images, like the setup and lighting that the IBT-C04 has. First of all, the setup is pretty easy. They say to charge the LiPo first, which took about four hours to do. Then it says to turn on the Siri/audio switch, and the mouse automatically goes into pairing mode for roughly two minutes as you move to whatever device you plan to connect to it.
Once the mouse is paired with your device, the IBT-C04 will say "power on," and "power off" in Siri's voice when the audio switch is moved. Additionally, the blips, swooshes, and even the ringer of the phone, along with any music stream, can all be heard from the mouse, and at a level slightly higher than our test phone supplied. Once that is all done, you can happily go along using it as a mouse while it streams music, and when the phone does ring, you can answer it by just moving a thumb to the phone button on the left side, and carry on about your business.
The mouse had no issues in transmission or reception of our movements, and we found the mouse to be very useful and accurate. The IBT-C04 is also sculpted to fit the hand very well, and will easily slide on any surface; however, clear glass can pose an issue with the sensor's ability to read correctly.
Even without knowing the exact DPI of the four levels, we hazard to guess they are about 600, 800, 1000, and closer to the 1600 max for the fourth level. So, even if the Bluetooth was never used, the IBT-C04 is really good in its basic functionality for any right handed user on the go. The only thing we can really complain about here at all is a slightly gritty feeling to the way the scroll wheel moved; other than that, we really enjoyed our time gaming and browsing with it.
Some may ask why the scroll wheel is clear, and it has to do with charging and pairing only. While the red LED of the Pixart sensor does make a slight glow on the wheel in normal use, it was not so much intended to be that way. The LEDs used in the wheel will illuminate red when the battery is charging, and will turn to a solid blue when it is fully charged. Once the cable is removed, the LEDs go out again, and the only other time you will see them while using the IBT-C04 is when the audio switch is first turned on. When the switch is first turned on, you will see a blue flashing denoting pairing is currently active. Once paired, the LED will again turn off.
As for the audio streaming aspect, we get it, but there is an issue with it as well. The audio is louder than our device of choice, and the sound is not all that bad considering what we have it coming from, but you can't really use the mouse and stream at the same time. Why? Because when you put your hand on the mouse, the palm of your hand blocks most of the speaker, and definitely kills the sound level.
We also tried the conversation aspect of the IBT-C04 out on a couple of occasions. With the mouse sitting on the desk top, my voice was broken up, and sounded pretty bad. After trying again on a pair of phones so we could hear both ends of the conversation, we found it is likely that our foot of distance, and the tiny hole for the microphone do not play well together. It wasn't until we had the mouse level with our mouth that our voices were heard loud and clear. So, what you end up with is one hand holding the rear of the mouse within six inches of your mouth. While this may be handy if the paired device is well out of reach, you will definitely get some strange looks if you do this anywhere but in the privacy of your own hotel room; we are sure of that.
In the end, the IBT-C04 is able to deliver everything SEENDA said it could, and with the low cost we see associated with other SEENDA devices, even without an exact MSRP at the moment, we know trying the device out for yourself will not break your bank. While it is a bit strange in concept, we do see the benefits in a portable mouse of this nature. We also understand the obvious move to incorporate the microphone for phone conversations. You are already Bluetooth connected, so why not?
Unfortunately, we really can't see ourselves using this very often at all. There are instances where this can be handy, like extensive traveling. As a mouse, it works very well for the price; however, it does lack functional side buttons for PC use, and at around $20 to $30, we like the IBT-C04 just as a mouse. The fact that it can stream decent sounding music and can take phone calls may not be what drives you to this product, but these can be a cool set of features for those with the desire and need for this sort of blend of technologies.
