If you want a party speaker with an auto-tune-style karaoke feature, the JBL PartyBox 310 is the closest match in the available manufacturer descriptions: JBL advertises built-in “vocal tuning” and dual microphone inputs. JBL does not explain how that tuning works, and its product page does not say a microphone is included. For a bundle with two wireless mics in the box, the PartyBox Encore is a clearer choice—but its documented echo and tone controls are not pitch correction.
That distinction matters: vocal tuning, pitch correction, echo, karaoke EQ, and removing the original singer from a song are different features. Here is what the cited JBL product information supports, and what it does not.

How to choose a party speaker for karaoke
Start with the vocal feature you actually want, then check whether microphones are included and how you will play karaoke tracks. A mic input only means the speaker can accept a microphone; it does not establish that the speaker corrects pitch.

- Vocal tuning or pitch support: Look for an explicit claim about changing or supporting vocal pitch. JBL describes the PartyBox 310 as having “built-in vocal tuning,” but does not explain the processing method. That wording is not enough to promise studio-style automatic pitch correction.
- Echo and tone controls: Echo adds ambience; bass and treble controls change tonal balance. They can shape a karaoke performance, but are not documented as pitch correction.
- Karaoke EQ: This describes equalization for karaoke. It should not be treated as automatic correction of a singer’s notes.
- Vocal removal: This targets the singer in the backing track, not the live singer at the microphone. JBL describes EasySing AI vocal removal on the Encore 2 Plus specification sheet.
The product claims below are manufacturer specifications and descriptions, not independent listening-test results. Features, package contents, and availability can vary by region, so check the JBL page for your market and the exact package before buying.

For a built-in vocal-tuning claim: PartyBox 310
JBL says the PartyBox 310 has dual mic and guitar inputs and built-in vocal tuning. This is the closest match among these cited products to a speaker advertised with vocal tuning. The product page does not define the effect or say that the box includes a microphone, so check the exact regional bundle and treat “vocal tuning” as JBL’s wording—not a guarantee of a particular pitch-correction result.
For two wireless microphones in the package: PartyBox Encore
JBL lists two wireless microphones, adjustable echo, bass, and treble, up to 10 hours of play time, and IPX4 splash resistance for the PartyBox Encore. These are manufacturer-listed specifications, not comparative test results; the cited page’s controls are vocal effects and tone shaping, not documented auto-tune. Verify the package contents on the regional product listing.

For karaoke EQ or room adjustment: PartyBox Ultimate

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Do you need an EasySing microphone?
JBL’s Encore 2 Plus specification sheet describes “Instant karaoke with EasySing AI vocal removal from any song.” That is a backing-track feature: it targets vocals in the song rather than correcting the live singer’s pitch. A secondary report describes pitch support on EasySing microphones, but the available product information does not establish a complete official microphone-compatibility list or regional availability. Do not buy a specific EasySing mic on the assumption that it works with a particular speaker or provides pitch correction on its own; check current JBL compatibility information for the exact combination.

Check these details before buying
- Identify the vocal effect you want. If pitch support is essential, look for an explicit, current product claim. Do not infer it from a microphone input, echo, EQ, or room-adaptation feature.
- Confirm microphones are actually included. A microphone input is not an included microphone. Check the exact product listing and package contents, especially for the PartyBox 310.
- Count singers and inputs. The Encore listing specifies two wireless microphones; the PartyBox 310 has dual mic inputs; the PartyBox 520 has two XLR inputs. Confirm the mic type and connection you plan to use.
- Plan your karaoke audio source. The PartyBox 520 page specifically describes USB-C connection to a streaming or karaoke app. For other setups, verify how your phone or playback device connects and whether the app supplies lyric display or vocal-removal features.
- Match the environment. JBL lists IPX4 splash resistance and up to 10 hours of play time for the Encore. Treat those as the manufacturer’s specifications for that model, not a promise about other speakers or every use condition.
- Verify local details. Product names, included items, compatibility, and availability may differ by region. Check the current JBL listing and seller’s package description rather than relying on a generic product name.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
