Availability may vary by region and online marketplace, especially for models sold under Naxa’s Sound Pro line.

How to Set Up the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231

To begin, fully charge the speaker using a compatible 5V DC power source before first use. Turn the power on, then select the desired mode using the input controls for Bluetooth®, USB, TF card, FM, or AUX playback. For wireless listening, activate Bluetooth® on your phone or tablet, search for the speaker name, and connect once it appears in the device list. If you want stereo pairing, use TWS to connect a second compatible speaker for wider sound coverage.

For microphones, plug a mic into the 6.3mm input and adjust the mic volume and echo knobs gradually to avoid feedback. Keep the speaker on a stable, dry surface, and maintain adequate ventilation around the enclosure. If pairing fails, turn Bluetooth off and on again, move closer to the speaker, and remove any old saved pairing records. If sound is distorted, lower the master volume and check the audio file format; the unit supports MP3.

Safety precautions: do not expose the speaker to rain, splashes, or high heat. Avoid overcharging, pulling on cables, or placing liquids near the control panel. Always disconnect power before cleaning or moving the unit.

Troubleshooting the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231

If the speaker does not power on, check whether the battery is charged and confirm that the 5V DC adapter is connected properly. If Bluetooth® will not pair, forget the device on your phone, restart both devices, and retry pairing in range. If USB or TF playback does not start, verify that the file is an MP3 and that the storage device is inserted correctly. If FM reception is weak, reposition the speaker away from walls and electrical interference.

Common user-facing issues on speakers in this class include low volume, echo noise, microphone feedback, and playback interruptions. Reduce mic gain, lower echo, and keep the microphone away from the speaker grille to prevent squealing. No specific error codes were listed in the available manual, so most fixes rely on power reset, source switching, and connection re-pairing.

Preventive care helps extend performance: charge the battery regularly, avoid deep discharge, store the unit in a dry location, and keep ports free of dust. Warranty terms may vary by seller or distributor, so check the purchase receipt and packaging documentation. For support, use the retailer’s customer service channel or the brand’s official support contact listed in the product documentation provided at purchase.

Pros & Cons of the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231

Pros

  • Not a premium PA system: Compared with higher-powered 12-inch party speakers, it is more entry-level.
  • Best for light to moderate use: Heavy bass enthusiasts may prefer larger alternatives with stronger amplification.

For value for money, the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231 makes sense if you want affordable Bluetooth speaker convenience with karaoke support.

Customer Reviews for the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231

Typical customer feedback for this type of portable Bluetooth speaker is mixed-to-positive, with many buyers praising the easy setup, colorful RGB lights, and simple control layout. A common rating pattern for budget party speakers is around 4.0 out of 5 stars, especially when users value portability and karaoke features more than raw output.

One frequent compliment is: “Great for small parties and easy to connect with Bluetooth.” Common complaints usually mention that the bass is limited, battery life varies with volume, and the sound is not strong enough for large outdoor events. Buyers often recommend it for bedrooms, dorms, patios, and family gatherings rather than professional DJ use.

If you are comparing affordable Bluetooth party speakers, this model is a good buy for casual entertainment, but not the best choice if you need high volume or long runtime. Frequent issues reported across similar speakers include echo adjustment, FM signal strength, and charging speed, so those factors should be considered before purchase.

Faqs

How do I set up the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231 for the first time?

Start by fully charging the built-in rechargeable battery before the first use. Then power on the speaker, switch to Bluetooth mode, and pair it with your phone, tablet, or laptop from the device’s Bluetooth settings. If you want to use the TWS feature, pair a second compatible NDS-1231 speaker after the first connection is complete. You can also connect USB, TF card, AUX, or FM sources depending on how you want to play audio.

Why is my sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231 not connecting to Bluetooth?

If Bluetooth pairing fails, make sure the speaker is in Bluetooth mode and that no other device is already connected to it. Turn Bluetooth off and back on on your phone, then move closer to the speaker and try again. Restarting both devices often helps. If the speaker still does not appear, clear old pairings from your phone’s Bluetooth list and repeat the pairing process. Checking that the speaker is charged can also prevent connection problems.

How does TWS work on the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231?

TWS, or True Wireless Stereo, lets two compatible NDS-1231 speakers play the same audio together without cables. This is useful when you want wider stereo sound or more coverage for a party, event, or outdoor gathering. Pair the first speaker to your Bluetooth device, then activate TWS on both speakers so they link with each other. Keep them within the recommended wireless range for the most stable sync and best sound balance.

Can I use the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231 with USB, TF card, and AUX inputs?

Yes, this portable speaker supports multiple playback options, including USB flash drives, TF cards, and a 3.5 mm AUX input. That makes it useful when Bluetooth is unavailable or when you want a wired connection for more stable playback. USB and TF support MP3 audio files, so make sure your media is in a compatible format. AUX is especially helpful for older devices, laptops, or audio players that do not pair through Bluetooth.

How do I get better sound quality from the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231?

For clearer sound, keep the master volume high enough to hear details but avoid pushing it to the point of distortion. Place the speaker on a stable surface or elevate it so sound can travel more evenly. If you are using two speakers with TWS, position them with some space between them for better stereo separation. Use high-quality audio files and adjust the microphone and echo controls carefully if you are singing or speaking through the included mic.

Why is the microphone not working on the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231?

If the wired microphone is silent, check that it is plugged into the correct 6.3 mm MIC input and that the mic volume knob is turned up. Also confirm the master volume is not muted or set too low. If echo is too strong, reduce the echo level until speech sounds natural. Test the microphone with a second cable or mic if possible, since a damaged connector can cause intermittent sound or no audio at all.

How long does the battery last on the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231, and how can I extend playtime?

The speaker uses a rechargeable 3.7V 1800mAh battery, so runtime depends heavily on volume level, lighting effects, and the input source you are using. To extend playtime, lower the volume when possible, turn off RGB light effects if you do not need them, and avoid keeping the microphone active unnecessarily. Charging the battery fully before events and storing the speaker with some charge also helps maintain battery health over time.

How should I clean and maintain the sound pro 12” Portable Speaker with Bluetooth® & TWS NDS-1231?

Use a soft, dry cloth to wipe the cabinet, grille, and control area after use. Avoid spraying liquid directly on the speaker and keep moisture away from the ports, knobs, and charging area. Store the unit indoors in a cool, dry place when not in use, and do not leave it exposed to dust or heat for long periods. Periodically check cables, the remote, and the microphone so small issues do not turn into bigger problems.
