Perfect for the shower or pool! Super compact with suction cup and lanyard. Sound is loud, clear, with solid bass for its size. Bluetooth connects fast, battery lasts ages (charge once a week). IPX8 rating means no worries about water – dropped it in the tub and it's fine. Surprised by the sound quality from something so small. Highly recommend for anyone needing a tough, portable speaker!

“This speaker really impressed me. The sound is loud, clear, and has strong bass for its size. I use it in the shower and the IPX8 waterproof rating has held up perfectly — no issues at all. The Bluetooth 5.4 connection is fast and stable, and the battery lasts a long time before needing a recharge. It’s lightweight, easy to carry, and great for the bathroom, home, or even the beach. For the price, the quality is excellent. Definitely recommend!”

I recently picked up the Monster Round One Wireless Speaker, and I’m genuinely impressed with what it delivers at this price point. Package contents: • Monster Round One wireless speaker • Aux cable • Climbing clip • USB-A to USB-C charging cable • Suction cup (perfect for shower use) Performance & Features: • Durability: Rated IPX8, so it’s built to handle water exposure without worry. • Connectivity: Bluetooth pairing was quick and effortless. • Sound Quality: The HD audio is crisp and powerful, with 360° sound that fills the room. • Calls: Built-in microphones provide excellent phone call quality—voices come through clear and natural. • Smart Control: A short press on the power button lets you summon Siri instantly. • TWS Feature: You can connect two of these speakers together for stereo sound. I couldn’t test this since I only have one, but it’s a great option for future expansion. • Battery Management: The auto-off function after Bluetooth disconnect or inactivity is a thoughtful touch that helps conserve battery life. This speaker nails the balance of price, sound quality, and portability. Whether you’re using it in the shower with the suction cup, clipping it to your backpack for a hike, or just enjoying music at home, it’s versatile and reliable. I would highly recommend it to anyone looking for a compact yet powerful wireless speaker.

The media could not be loaded. This small speaker impressed me more than I expected. The sound is clear, loud, and fuller than what you’d think from its size. The IPX8 waterproof rating gives real peace of mind, so I can use it in the shower or near the pool without worrying. The battery lasts well for daily use, and the strap makes it easy to hang or carry around. It connects quickly to the phone and stays stable without cutting out. Overall, it’s a practical and durable speaker that works great for everyday use and for taking music wherever you go.

I picked up this portable speaker because my old shower speaker finally gave up on life after one too many kid bath splashes and accidental drops, Our house gets loud and chaotic pretty much all day so having some music in the background helps me stay sane, I figured getting something a little more heavy duty would be worth it especially since half of our weekends end up outside or at the pool When it arrived I tested it in the kitchen first and the sound caught me off guard because it was way clearer and louder than I expected from something this size, The bass had a good punch to it without rattling or sounding cheap, My spouse actually turned around and asked what I bought this time which is always the sign that it sounds better than my phone speaker ever could, The kids immediately insisted on playing their songs so we went through about fifteen different tracks before I even got to test it in the shower The waterproofing works great which I learned by accident when the six year old dropped it straight into the tub while it was still playing, I grabbed it thinking it was done for but it kept going like nothing happened, The battery also lasted longer than I thought and I only charged it once over the weekend even though we used it outside during yard work and again at night when we tried to unwind It feels sturdy without being heavy and it hooks easily on shower racks tree branches and even the stroller when we are out for a walk, The Bluetooth connection has been solid too and I havent had any random disconnects which used to drive me crazy with other speakers For something this portable it has been a really solid upgrade and honestly makes mornings a little better which is saying a lot around here I currently highly recommend this product. However, should issues arise I will update my review accordingly.
