Review: This thing packs a punch - If you like deep thumping bass, boy is this thing for you! Dance music sounds epic through this, as does reggae and pop. If that isn't your thing, no problem, Just go to the EQ in the app settings and tweak the sound to your liking or choose one of the many presets supplied. You will get something that suits your audio needs. Sound is detailed, smooth and full, I enjoy listening to this alot and find it handy in the office to stream radio shows to. I even used it as a sound bar for my TV by plugging in a cable from the TV headphone socket into the Aux in on the UBOOM and it straight away switched to that input and I had glorious deep sounds without any delay. No doubt you could also do this via bluetooth but my TV doesn't have that functionality. As with most EarFun products you get to control most things via the app including the lights on the front. You can specify colours, whether they stay on permanently or flash in time with the music. Select the black colour to switch them off completely. You can also set EQ, automatic shutdown time and upgrade firmware. This thing allows you to recharge your phone as well. via the Output USB socket behind the waterproof cover on the back. They do seem to have thought of everything. The item weighs in at 4.2kg and comes supplied with a detachable shoulder strap. Overall I am very impressed with this, the sound quality is good, it goes very loud, sound staging is quite wide, you can buy two and link them for a stereo pair (It can pair up to 50 units) the battery life is excellent at 30 hours and it took me 4 hours to fully charge it (It came partly charged). It is also very well made with no dodgy misaligned panels or connectors like you find on some of these things. Although it's primarily plastic, it feels premium, the metal grill on the front is very well finished and the weighty feel makes you feel like you've got your moneys worth. You can even use it to send and receive phone calls as it has a built in mic. If there is one thing I'd like to see it would be Siri or Alexa support through the built in mic. That would truly be the icing on the cake. It does play Siri results through the speaker but it uses the phones microphone to pick up your voice. The only other thing I'd like to see is more highly tuned but smooth tweeters as I do like to hear percussion instruments like Hi-Hat and tambourine. To hear these at a volume I like I've had to increase the 8k and 16k frequency EQ bands to their max and then reduce the 2k and 4k bands to -5 each to get a sound that wasn't too harsh. I'm just nit picking though for my personal tastes. Overall though I'm very pleased. Nice one Earfun. 10/10
Review: Top sounding Bluetooth speaker. - If you use your own equaliser settings, you can't get a better and louder sounding speaker. Unbelievable at the price. I've had them all. Soudcores, JBL, Tribit and many more. Great speaker. At the price, you could buy 2 for the same price as the JBL speakers.

### ⭐⭐⭐⭐⭐ Wonderful Sound Quality so impressed
*by P***L on 13 November 2024*

I watched a few reviews online and I was a little unsure whether to get it, but I did. Lol And boy, oh boy😳 it was amazing 👏 🤩 Ok, it's heavy and I've tried to get the 4 lights to stay fully on when charged???? I even returned on thinking 🤔 it to be faulty, I don't know 😕 🤔 this one as done the same and I've been to sleep all night with it on charge with a vdc20/3A charger as stated but only 3 lights stay on. Ok that's my moan out the way. 😆 Hey, the bass/roundness and the crispiness ohh man. Sounds better than my car, and I've got a sub in there. 😆 🤣 😂 Excellent little gym speak to connect my phone to in my garage. So, I've given the Pro and the Cons. Hope it's useful to whoever. Cheers 🍻
