Oraolo 40W Portable Bluetooth Speaker with Stereo Sound, IPX6 Waterproof, USB/AUX Input, Built-in Mic - Perfect for Home Parties, Outdoor Adventures & Travel

I wanted a better bluetooth speaker to use around the house and outside. I wanted something loud enough to fill my two car garage, while still sounding good. This meets all those requirements.It is pretty lightweight for its size. Construction is all plastic with a metal mesh grill and a rubber handle. The handle on top kind of tucks down so it will lie almost flat, then will pull out to provide more slack to pick up the speaker. The whole left side is home to the four button controls that is covered by silicone rubber. The back has a silicone cover which hides three I/O ports: 3.5 mm stereo jack for aux input, micro-USB for power to charge, and a TF (micro-SD) card slot for music storage. I would have liked to see a 3.5 mm stereo output to provide the capability of hooking up another speaker. The rubber cover seals extremely well - almost too well. It is hard to get open when closed up. The bottom has silicone rubber anti-skid feet, which work well.Operation is pretty straight forward. The controls on the left side are M for mode, volume up/next track, play-pause/power, and volume down/previous track. Powering on requires a long press on the power button. Pairing bluetooth requires a long press on the M (mode) button. When pairing, the unit does not sound a tone when it becomes visible to bluetooth devices, which was unexpected. If there is a TF card installed, the unit will automatically continue playing music from the TF card. It does remember where it was playing when it was last shut off. To switch to bluetooth, press the M (mode) button. I do not know what music formats are playable from the TF card. The documentation does not say what files types are supported. I have only tested mp3s, which play perfectly.Sound quality is decent for a bluetooth speaker. This is not a bass machine. It completely lacks sub-bass, and has a little bass just higher than the sub-bass register. What it does have is mid-bass, and quite a bit of it, especially on the low end of the mid-bass range. Frequencies higher than the lower end are fuller and sound really good. Vocals are extremely clear, and highs are great. Mid-base through the vocal range is where this speaker shines. It throws these frequencies far, and fills a room quite well. Volume is outstanding. It will fill a large area. I have access to a 35' by 40' workshop and it fills this area effortlessly. Overall the sound performance is good, and quite enjoyable. It's not a party thumper, and it won't rock the block, but it works great for provide music while doing chores or working out in your home.Bluetooth works well. Pairing was trickier than I was expecting because it did not sound a tone when it started broadcasting for pairing. I had to constantly refresh and monitor my phone to pair the speaker. After it was paired, it worked as it should. I haven't tested its range, but I'm guessing this is not a long range device.I have not tested battery performance. I have not drained the battery. One thing to note is the instructions that came with the speaker say to not charge the speaker with it turned on. The instructions say this is to "avoid making the speaker work abnormal". I guess this means that charging while playing music is not recommended.I have not tested the aux input function, but I assume it should work as expected.In summery, this is a great speaker, and a wonderful value. I am very satisfied with this purchase.
