AI Verdict
This is a super-portable, fully waterproof speaker for your shower or backpack that gets surprisingly loud but has almost no bass.
This speaker is a strong fit if your top priorities are extreme portability and waterproofing for use in places like the shower or on a kayak. Its sound is clear for vocals and podcasts, but the lack of bass makes it a weak fit for anyone who wants a powerful music experience.
If you need more bass and longer playtime, look for a larger portable speaker with at least 10-15W of output power and a listed passive radiator.

What Buyers Say
The most surprising thing about this speaker is how loud it gets for something the size of a golf ball. It's perfect for clipping to a bag or putting on a shelf in the shower. The IP67 rating is legit; it can handle being dropped in water. Pairing is quick thanks to Bluetooth 5.3. The biggest letdowns are the battery life, which is cut in half at high volumes, and the complete lack of bass. Don't expect it to power a party, but for personal listening to podcasts or pop music on the go, it's a solid little gadget.
“i literally threw this in the shower and it was fine and it gets so loud for a little guy but there is ZERO bass so my rap playlists sound kinda sad lol.”
Common Praise
- Impressively loud and clear for its tiny, 3-ounce size.
- The IP67 waterproofing works as advertised, surviving submersion and use in the shower.
- Bluetooth 5.3 connects quickly and maintains a stable signal.
- TWS pairing two speakers together is easy and creates a good personal stereo soundstage.
- The built-in microphone quality is decent for taking calls.
Common Complaints
- Bass is weak to non-existent, making bass-heavy music sound flat.
- Real-world battery life is only 3-5 hours when playing at loud volumes.
- Sound begins to distort at the highest volume settings.
- It cannot be used while it is charging.
- The included lanyard feels cheap and flimsy.
Ownership Tips
- You'll find yourself charging it more often than you'd think, especially if you like listening to music loudly.
- The single power button controls play/pause and TWS pairing with different numbers of clicks, which takes some getting used to.
- Because it's so small and light, it's easy to forget it's in your bag, which is both a pro and a con.
- The smooth plastic body gets pretty slippery when it's wet.
Frequently Asked Questions
Can you pair two of these speakers together?
Yes, you can pair two C17A speakers using the TWS (True Wireless Stereo) feature for synchronized stereo sound. To do this, turn both speakers on and triple-click the power button on one of them to initiate pairing.
How long does the battery actually last?
The battery lasts about 7-10 hours at medium volume. However, at higher volumes (around 75%), expect closer to 5 hours of playtime.
Is it really waterproof?
Yes, it has an IP67 waterproof rating, which means it can be submerged in water. It's designed to be used in the shower, by the pool, or in the rain without issues.
Can I use the speaker while it's charging?
Some user reviews indicate that the speaker does not charge and play at the same time, which can be an inconvenience.
How do I fix pairing problems?
If the speaker won't pair, make sure it's in pairing mode (flashing blue light) and close to your device. Try turning your device's Bluetooth off and on, or 'forgetting' the C17A from your Bluetooth list and re-pairing.
How good is the bass?
The bass is very limited due to the speaker's small size. While the sound is clear for vocals and mids, it lacks the deep punch you'd find in larger speakers.
Buying Guide
For a speaker this small and cheap, you're paying for portability and waterproofing, not sound quality. Think of it as a significant upgrade to your phone's speaker that you can take anywhere without worrying about it. Manage your expectations about bass and battery life; physics still applies, and a 3-ounce speaker can't produce deep lows or play loudly for 12 hours.
IP67 Waterproof
The '7' means it can be submerged in up to 1 meter of water for 30 minutes. The '6' means it's totally dust-tight. You can literally use it in the shower, drop it in a pool, or take it to the beach without fear.
TWS (True Wireless Stereo)
This lets you buy a second speaker and link them together. Instead of one speaker playing both left and right channels, you get one dedicated left and one dedicated right speaker for a real stereo effect, like a mini pair of bookshelf speakers.
5 Watts Output Power
Wattage is a rough guide to loudness. For a tiny speaker, 5W is actually quite a bit and explains why users are surprised by its volume. It's enough for a small room or personal listening outdoors, but won't cut it for a noisy party.
Alternatives
If this isn't enough, look for speakers that specify a 'passive radiator' for improved bass. For longer battery life, search for models that list their battery capacity in mAh (aim for 2000mAh+) and have at least 10-15W of power for better outdoor performance.
