JBL party speaker with wireless microphone now available cheaper. It was released recently and offers 100W power and a light show

The JBL PartyBox series is among the most popular choices for those who want a portable speaker with serious power and extra features. You can now get the JBL PartyBox On-The-GO 2 at Alza for 7,642 CZK with discount code ALZADNY15. Given that it’s a new product from January 2026, a 15% discount right at the start of sales is unusual.

Quick summary:
✅ Makes sense if you’re looking for a portable speaker for outdoor events, parties, or karaoke and appreciate a microphone included in the package.
⚠️ Consider if you primarily need home audio or prefer a neutral sound profile without emphasis on bass.
💡 For 7,642 CZK you get a complete party solution including a wireless microphone – with competitors, you would often buy it separately.

Why this speaker is interesting

The PartyBox On-The-GO 2 targets users who want one compact package for outdoor events. The speaker combines solid performance, an integrated light show, and most importantly, a wireless digital microphone included in the package. This is rather an exception among competitors in this price range – microphones are usually sold separately for 1,000–2,000 CZK. Practically, you get a ready-to-go karaoke set.

Compared to the first generation, the new model brings Bluetooth 5.4, JBL Auracast support for connecting multiple speakers, and an improved shoulder strap. The IPX4 resistance remains, protecting against rain or splashing water by the pool.

Sound and features you’ll appreciate

The speaker features 100 W of power and a frequency range of 50 Hz – 20,000 Hz. JBL traditionally emphasizes stronger bass, which suits party music, electronic music, or pop. Dual silk tweeters ensure clearer highs than the previous generation. It’s not an ideal choice for home listening of classical music, but for outdoor events, the sound performance is more than sufficient.

The dynamic light show synchronizes with the music, adding a visual dimension. It can be controlled via the JBL PartyBox app, where you’ll also find an equalizer and the Smart Key Change function – which adjusts the song’s key to your vocal range for karaoke. The wireless microphone also has a built-in echo effect.

Practical aspects: battery life, portability, connectivity

The manufacturer states up to 15 hours of battery life on a single charge, which in practice depends on volume and light show usage. The option of fast charging is interesting – 10 minutes in the socket adds approximately 80 minutes of playback. The battery is also replaceable (a spare is sold separately), so you can have a backup ready for longer events.

The speaker weighs approximately 5 kg and has an integrated handle and a shoulder strap included in the package. It’s sufficient for carrying around the garden or to the beach, but keep in mind it’s not a pocket-sized device. For connectivity, you’ll find Bluetooth 5.4, a 3.5mm jack, and USB-C for connecting other sources.

The True Wireless Stereo function allows pairing two units for stereo sound. For larger events, multiple JBL speakers can be connected wirelessly via JBL Auracast.

When it doesn’t make sense

If you’re primarily looking for a speaker for home listening and care about neutral, balanced sound, the PartyBox won’t be an ideal choice. Similarly, if you don’t need karaoke functions and a microphone – in that case, you’re paying for something you won’t use. For purely home use, there are higher quality alternatives at a similar price, such as from the JBL Xtreme series or competitor Marshall.

Also consider its size and weight. For hiking or backpacking, the speaker is unnecessarily large. For these purposes, a smaller model like the JBL Flip or Charge makes more sense.

Verdict: who it’s worth it for

The JBL PartyBox On-The-GO 2 for 7,642 CZK is an interesting offer for those looking for an all-in-one solution for outdoor events. You get a speaker with sufficient power, a light show, water resistance, and a wireless microphone in one package. Moreover, such an early discount on a new product is not common.
