I would be interested in testing the Soundcore Motion Q.
The main purpose of my test plan would be to test the quantifiable claims made by the product. "It sounds great" or "it's nice and loud" sound nice in a review but don't really give any kind of concrete results as far as an actual test goals.
My test plan is as follows:
(1) Playtime: From a user perspective, this is arguably the most important feature of the product -- the ability to not just play the speaker for extended period of time, but to be able to play for the advertised amount of time using a useful level of sound. If it lasts the advertised amount of time at low listening levels, that's not exactly what the user has in mind. Someone buying a high-quality active lifestyle speaker is going to look for long playtime at high volume and heavy continuous use. This might not be a speaker you're going to use for a rager, but it is exactly the sort of thing you'd want for your backyard pool party. It needs to last.
Test Plan: Full volume playback from full charge to power off.
Test Goal: Advertising for the Soundcore Motion Q boats "up to 10 hours of playtime." Obviously I'll try and exceed that in testing.
(2) Volume: "It's loud" is not enough. We're looking for quantifiable measurements. This test will use a decibel meter to get both a numerical measurement of volume and will also be used to compare decibel levels to other "competing" speaker sources. For example, someone looking to buy an easy, on-the-go speaker such as the Motion Q will likely be using it to replace their own phone's speaker that they might use in the shower or just in the backyard.
Test Plan: Full volume decibel level measurement, and comparing those decibel levels to the Galaxy S9+ speakers (advertised as the loudest speakers ever put in a cell phone) as well as other bluetooth connected speakers.
Test Goal: Obviously we'll be hoping to see the Motion Q exceed volume levels of the other tested products -- hopefully considerably so, in the case of the cell phone(s).
(3) IPX7 Waterproofing: IPX7 waterproof means the device should be able to survive being submerged in 1 meter of water for 30 minutes without damage.
Test Plan: Pretty simple, really. We're going to actually test that claim. 30 minutes, 1 meter underwater. It'll be playing music during that time too.
Test Goal: Well, clearly we're looking for no physical damage, but we're also looking for no sound distortion after that 30 minutes as well, as some speakers that make this claim don't quite make out as well as you'd hope. 1 meter underwater for 30 minutes is pretty extreme -- but you're basically looking for that shower to be safe for the speaker or a spill into the pool to not damage your purchase.
(4) Bluetooth Range If you're in the backyard listening to music, walking around, grabbing a burger, you want to be able to roam and easily skip through your playlist without having to run back over to the speaker. The ability to keep your phone in your pocket while playing music is a big plus.
Test Plan: I'll be playing music, and going as far away as possible before a reliable bluetooth connection starts to skip.
Test Goal: Advertised bluetooth range is 66 feet. Anything beyond 66 feet would pass the test.
(5) Other Non-Quantifiable, Non-Advertised Claims: Not everything is perfectly measurable, but there are some things you can still test reliably even if you don't have a measurement to go by.
Test Plan: Other items to be tested are durability (a moderate drop test) and quality of sound (comparing sound distortion at high levels to other bluetooth or cell phone speakers at similar volumes).
Test Goal: Ideal durability would be surviving a 1 to 1.5 meter drop -- i.e., bumped off the picnic table or falling out of your backpack while you're on a bike. Quality of sound should be significantly better than a loud cell phone speaker or a comparable quality bluetooth speaker.
Review would be posted on Amazon. That's certainly the place where it would have the most "bang for your buck," as you'll be right in the eyes of someone actively considering to buy the speaker and comparing with others.
Thanks for your time, and I hope to be able to participate in testing!
