This is a review of Altec Lansing Hydramotion 2.0 Bluetooth speaker. It's cylindrical shape makes it easy to fit into a cup or bottle holder in your car or bicycle.If you stand the speaker up vertically so that the plus button is on top, the left and right drivers would be in the correct place. The stereo effect is barely noticeable, but then they never say it is stereo.If you try to watch a movie with this speaker, you may notice when people talk their lips don't sync with the audio. I measured the latency with a camcorder and it is about 280ms, plus or minus 33 ms. It's good enough for listening to music. More expensive Bluetooth speakers may have shorter latency.Of the various Bluetooth speakers I own, I especially like using this one when I'm moving around in my apartment kitchen because my kitchen are full of stuff everywhere. Other horizontally oriented Bluetooth speakers take up too much space and are harder to find space to put them down. This speaker, however, when used vertically can easily fit into small spaces.In the horizontal position, the speaker have a pair of feet but are very short, so you may find it rolling away once in a while. Among the various Altec Lancing Hydra series speakers, I find this particular one, Hydramotion, easiest to associate with the product.When paired to windows11, even though windows11 has volume 0 to 100, the speaker does not produce a volume change at each volume level. At level 0 to 5, it is silent. At level 6 is the first audible level and the volume stays the same until level 12. It takes about 6 or 7 level increase to cause an actual volume increase at the speaker. The plus and minus buttons on the speaker itself always cause a volume change, because it changes the volume level by 6 or 7 each time.When paired to an Ipad mini 6, I could not find a volume level suitable to fall asleep with. It's too loud or too soft. Otherwise the sound quality is good. At the loudest volume, the sound can fill a living room and has no obvious distortion.PROs nice looking, colorful lights, doubles as a power bank, tripod screw hole, fits in cup holderCONs no aux input, volume control not smooth
