The AUX input is a 3.5mm analog line-in that lets you play audio from a device with a headphone or audio-out jack directly through the speaker. It’s handy when you want a quick, reliable connection without pairing.

• Plug-and-play backup when wireless isn’t available.
• Lower latency than wireless, helpful for videos or games.
• Works with many devices, from laptops to portable music players.

Look for labels like AUX or Line-In. You’ll typically need a 3.5mm male-to-male cable. Start with volumes low, then raise gradually. Sound can vary with your source device and cable condition, and very long cables may introduce noise. Keep ports and cables dry; if your speaker is water-resistant, close any rubber flap when not using AUX.

1. Power on the speaker and select AUX/Line-In mode (often via a Mode button).
2. Insert a 3.5mm male-to-male cable into the speaker’s AUX jack.
3. Plug the other end into your phone, tablet, laptop, or computer’s headphone/audio-out port. Some phones without a headphone jack may require an adapter.
4. Start playback, then adjust volume on both the source and the speaker.

• If audio is quiet, raise the source volume before the speaker’s.
• Hiss or crackle can come from loose plugs or a worn cable—reseat or try another cable.
• On desktops, use the green audio-out port.

These steps can help you get a stable connection, but results may vary based on your device and cable.

“Better” depends on how you’ll use your speaker. Rather than focusing on a name, compare what matters for your needs.

• Sound: Look at driver size, passive radiators, and stated power (RMS vs peak).
• Durability: Check the IPX rating if you’ll use it outdoors or near water.
• Connections: Decide if you want AUX-in, USB, or memory-card playback.
• Battery & portability: Consider size, weight, handle/strap, and estimated playtime.
• Features: Bluetooth version for stable connection, TWS pairing, and lighting effects.

Compare specs and customer reviews on product pages to see how real users rate loudness and clarity. The best choice is the one that matches your priorities.

AUX-in is versatile and accepts most line-level audio sources.

• Phones and tablets with a headphone or compatible audio adapter.
• Laptops and desktop computers.
• Portable music players and media devices.
• Some TVs via their headphone or analog audio-out jack.

Use a 3.5mm male-to-male cable, or a 3.5mm-to-RCA cable if your device has red/white audio outputs. AUX is intended for line-level signals, not microphones, unless the speaker has a dedicated mic input. For best results, set your source volume to a moderate level and fine-tune on the speaker. Check the product description for the exact jack type and any included cables.

Many portable speakers list water-resistant ratings (such as IPX5–IPX7). Plugging in an AUX cable usually requires opening a port cover, which can reduce water protection while it’s open.

• Keep the AUX port and cable dry during use.
• Close the rubber flap firmly when you’re done.
• Avoid submerging or exposing the open port to heavy splashes.
• Review the product’s manual for its specific IP rating and guidance.

Water resistance varies by model and conditions. If you’ll be near water, wireless playback can help keep ports sealed, while AUX is generally better for dry environments.
