I may not be a music expert, but I do love listening to great sound and this QFX BT-ZX35 Powerful & Portable Waterproof All Terrain Bluetooth Speaker completely exceeded my expectations!I turn this on and I was blown away by the sound and deep bass. It’s the perfect companion whether I’m relaxing indoors, hosting a backyard get-together, or heading out for some outdoor fun. The dynamic LED party lights are such a fun bonus adding a cool, festive vibe that makes the experience even better.What really gives me peace of mind is its IPX7 waterproof rating. I’ve used it poolside and didn’t worry about water splashes at all. It’s built tough and feels durable, making it perfect for camping, beach days, or just tossing in a bag for travel.I also love how versatile it is whether I want to connect via Bluetooth, AUX, or even just tune into some FM radio, it’s got all the features I need. Plus, the USB-C fast charging keeps it going without long downtime.If you’re looking for an all in one fun, and powerful speaker, this one is definitely worth checking out!

The QFX BT-ZX35 delivers powerful sound with deep bass that really brings the party to life. I love the LED party lights—they add a fun vibe whether I’m indoors or outside. It’s compact, waterproof, and super easy to carry thanks to the built-in handle.The Bluetooth connection is fast and stable, and the USB-C charging is a huge plus. It also has FM radio and AUX options, which make it even more versatile.Perfect for beach days, backyard gatherings, or just jamming out at home. Totally worth it for the price!

Why did you pick this product vs others? Firstly /I have owned 4 of thes products (5 years old now and remarkably, "The internal rechargable batteries are still working!") Secondly, "This 2025 model is clearly an superior upgrade to the four previous models that I still use today!" The newly upgraded lights, The USB-C charging and the FM radio edition are truly awesome features; not to mention the fact that one unit can be effortlessly paired with an additional unit and just know, "They will blow your socks off as the sound is so incredible (Deep Base / Perfect Midrange and High Tweeter) undistorted and extremely loud if you want it to be! (Great for indoor and outdoor poolside party events) Thirdly, "Purchase two of these and pair them together the sound is incredible with Complete Bluetooth control from 60+ ft away!

Charge only lasts about 5 hours. Very loud and colorful

Very limited battery life if using the led lights. The battery will last longer with them turned off. To me that's a deal breaker. The purpose of buying this was using the music with led lights. I haven't dumped it in water but have gotten it wet and works fine. If the battery power lasted longer this would be so much better. Gets old having to hook it back up to the USB cable again and again when it drains after just using it in the shower for a few days. Needs a much bigger battery. As far as looks it looks great when the lights are responding to the music. But when using it to save power turning the led's off it looks very basic. Just a plain Jane looking Bluetooth stereo. Too be clear I like QFX Bluetooth speakers but the battery power needs to be addressed. I own several QFX speakers from small to 15 inches. If the engineers are reading this on the next version just make it a size bigger unit to put in a larger power supply.

For under $60, the BT-ZX35 is a seriously solid buy. It looks like a two-way design with dual 2.7" woofers and two tweeters, plus front, and back passive radiators gives it surprisingly punchy bass and clear highs. The 12-hour battery claim sounds promising, but I haven’t fully tested it yet. I wish this had EQ modes, but honestly, the stock tuning is clean across genres. Bluetooth was straight forward with my iPhone 12 Pro Max with no problem, and the IPX7 waterproofing, LED lights, and FM radio make it a great all-terrain speaker. If you want rugged sound on a budget, this one punches above its price. Very well packaged! 5 Stars!

This speaker blew me away. Delivers powerful sound with deep bass that you can actually feel. It’s built tough and waterproof. I’ve used it at the pool, beach and even during a rainy BBQ with no issues. The LED party lights are a fun bonus and really set the vibe!It charges fast with USB-C and the battery lasts longer than expected. I also love that it has FM radio and AUX port super versatile. It’s compact enough to carry anywhere but loud enough to power a party. Definitely worth every penny.

Really happy with this purchase. The sound is clear and loud enough for everyday use, both indoors and outdoors. It’s compact, easy to carry, and actually waterproof — I’ve used it in the bathroom and by the pool without any issues. Battery life is solid, and it pairs with my phone in seconds. For the price, this speaker is a great value. Definitely recommend.

I'm happy with the sound but they are an ugly orange instead of black. I thought about returning them but can't be bothered so I'm hiding them instead.

Small, neat and very attractive. I was expecting sedate black but they arrived a vivid orange! Good quality sound.
