Muy buen tamaño el Sonido es excelente permite subir al máximo sin distorsión conecto fácilmente a PC y Android el brillo y el bajo es excelente para reproducir tu música, falta ensayarlo con juegos de vídeo a ver que tal, El tamaño es justo, por ahora sigo probando la duración de la batería les estaré comentando como nos va.

Physical - The speaker has a solid construction and heft feeling substantial in the hand but not heavy. It feels like it would hold together if dropped although I did not intentionally test it. The strap is effective for carrying. I won't personally sling it over my shoulder and carry it as a boom box but if you do understand that the strap is not long. The buttons are large and easy to read which is a lot different from other bluetooth speakers I have used in the past. The speaker is rated for IPX5 which means it is not rated for dust but is rated to survive short exposure to water jets which is perfect for outdoors unless you drop it in water or leave it in the rain for an extended period. Overall it is excellent construction.

Power - The speaker comes with a USB C cable but no charger. The power meter LED's are a nice addition helping prevent a surprise low battery. I have not timed a full charge to discharge but it is advertised at 40 hours. You have the option of using the speaker battery to charge your mobile device. This is a handy option especially if you are streaming music from your mobile device. Of course this will reduce your play time. Overall this has an excellent battery that will outlast your stamina to listen.

Bluetooth - The speaker paired very quickly with my Amazon Echo device and Avantree Bluetooth transmitter. It maintained a solid connection up to ~55 feet which aligns with the stated distance of 60 feet. The speaker is NOT advertised to have APTx compatibility for low latency bluetooth communication which would allow it to be used as a TV speaker. When connected to the avantree/TV with aptx there was noticeable delay with the sound not synced confirming that it is not APTx compatible. Overall it connected quickly and performed to the advertised distance.

Sound Quality - Sound quality was good in the base equalizer mode but felt 'empty' without it. You can't expect audiophile quality from a single bluetooth speaker. Since I only have the 1 speaker I cannot comment on the sound quality improvement from using it in the stereo mode. I played Magic Mike 'Drop that Bass' and at maximum volume there was no distortion from the bass. Overall it was very good for an inexpensive bluetooth speaker.

Improvement Recommendations
+ A dedicated bluetooth pairing button would make it easier to use without having to remember to hold the plus and minus buttons at the same time.
+ Labeling for the LED's would provide benefit instead of trying to remember what each one means.
+ I experienced pairing issues when switching from the avantree back to the echo. I had to turn off the avantree before the echo would pair correctly.
+ Adding APTx would make this a more versatile bluetooth speaker.
+ Adding a USB charger to the product would make sense to prevent the consumer from having to find a charger with the appropriate AMP rating.
+ Improving the IP rating to IPX6 would allow the consumer to feel confident taking it on a boat or using it poolside without worrying about it accidently dropping into the water.

Here's the speakers I tried:

Tribit XSound Go (kept it and love it, for listening inside in a quiet room).

Logitech Roll 2 (Kept it, only use it for listening to videos because the other speakers I liked better for sound, but they have an audio delay when watching videos).

Oontz Angle 3 Ultra - I thought it sounded muddy. Returned it.

Aomais Go-Jr - pretty good sound but it wasn't quite loud enough for what I wanted it for (listening outside). Returned it.

Aomais U-go - I thought the sound was better on the Go-Jr even though the battery is better on the U-Go. They weren't too different though, and neither was loud enough for me for outdoor listening. Returned it.

Anker Soundcore Motion+. The sound quality on this thing was awesome, and volume was very good for its size. I like that it can be paired with another in stereo. It looks and feels high quality. I'd have kept this one for indoor listening over the Tribit if price was no object. I'd have kept it for outdoor listening if I wanted my solution to be compact. However, my priority was high volume high quality sound, and for that, the W-King D8 beat the Anker by quite a margin.

Alpatronix "60W" speaker that looks identical to the W-King D8. They advertise it as "updated" from 40W to 60W. I don't buy it. To me, the D8 was clearly louder and had better sound at the higher volumes. The sound on this thing was great though. It's a solid pick. I just thought the D8 was the obvious winner.

Finally, the one I kept and love: W-king D8. IMO, it looks like crap. Its big, heavy, and cheap looking, and has a big ugly W-KING written on it. But the sound knocks the socks off everything else I tried. I use it outdoors for hosting little dance parties, and I also listen to it indoors. At low volumes I think it's a bit bass heavy, but the bass drops off to an even level at volumes 50% and above. Indoors I listen to it around 60%. Outdoors around 90%. I like that this thing doesn't live in max volume, like my other speakers do. A good sign. I bought a second one and they paired well with each other. The sound is amazing, rich full, loud. Batterly life isn't super great. I only get maybe 4 hours or so at high volumes.

I purchased 3 different 40W to 50W claimed boomboxes.
I got the Bugani, the angular looking with black and orange accents.
The WKing
And this Alpatronix model.

All 3 sound different! The W-King sounded the most tinny and "non-live" out of the 3. The Bugani sounded pretty good, and I think did sound best. The Alpatronix sounded better than the W-King although they almost look identical. If you look close you will see different speakers, which give a warmer "live" sound.

None of these sounded fantastic or anything, and the EQ, you cant even tell what its on helps a bit, but you cant really use it knowing what is happening, as by the time you change and listen enough, you are done with the song, and no way to know what you cycled. All 3 do this BS EQ. It makes a sound difference, but it could have had a indication of what you like in general vs maybe vocals, etc.

Another annoying thing is all these units have the Volume AND the skip control in one button, and even when you get used to it, you can inadvertently skip the song and need to go back, and its just lame not to have a jog dail volume control, no excuse but cheap electronics board design.

So Pro Con list, and why I returned the Bugani...
The handle I though could fold down. It DOESN'T, so that will eventually get crammed or broken, or just be in the way. No shoulder strap like the others, and the others are more compact, partly due to the handle free design.
I general Bugani is less "on the go" than the other design. Although aesthetically nicer than a black plastic tube with some aluminium grill and lame logo slapped on. The light indications on the Alpatronix design is easier to see, while Bugani has LED indicators behind the grill. No bueno.
All 3 crank plenty sound, but the Bugani suffers sooner.
What I also found important is how well they sound at low settings.

So between the 2 twins, what are the differences...??
The speakers are different, AND the Alpatronix has a SD Slot, AND USB-C charging!!!
AND its $20 less!, AND sounds better! IMO

The others have standard USB charging and no card slot.

So while neither of these have a high fidelity open and comfortable sound processing to them, they still sound decent, and add a lot of sound to a room, or at the pool side.
For under 70, its not a bad deal at all. I don't see a point in spending more than 50-75 on portable sound that is just background music. For real sound, you can get great headphones, or a great car system, or home system.
But for Bluetooth streaming sound, its fine.

This speaker goes with me on my work route every single day. I use it for listening to music, taking phone calls, and I don't have to worry about its battery running out on an average day in the truck.
