Stylish Yenkee speaker on Alza discounted to a minimum! It costs less than 2 thousand and offers beautiful design and great performance

A Bluetooth speaker with a retro look and metal controls usually catches the eye before the ear, but this one aims for both. You can now buy the YENKEE YSP 55BK MAMBO L with code 2026ALZAEXTRA20 for 1,919 CZK, whereas it cost 2,999 CZK at launch. It hasn’t been cheaper on Alza yet.

Quick summary:
✅ Makes sense if you want a stylish home speaker with powerful sound and the ability to manually adjust bass and treble.
⚠️ Consider if you need a high-quality Bluetooth codec (AAC/aptX) or expect a charging adapter to be included in the package.
💡 For 1,919 CZK you get metal, retro design, and rotary controls that cheaper “boxes” usually don’t have.

Why this speaker is interesting

This speaker from YENKEE relies on a retro design in the style of classic Marshall speakers – a matte black body, a prominent front grille, and metal controls. But it’s not just about looks. Inside, there’s a large woofer and a separate tweeter, designed to handle deep bass and clearer treble, and a total output of 45 W is sufficient to fill a typical room with sound. A practical handle makes it a piece you can easily move from the study to the kitchen or terrace.

Key parameters explained in plain language

The speaker operates in a frequency range of 50 to 20,000 Hz, which is a decent range from bass to treble. You can connect it via Bluetooth 5.3 with a range of up to 10 meters, but also by cable – it supports 3.5mm AUX, USB flash drive, and microSD card and plays common formats including MP3 and FLAC. An interesting feature is True Wireless Stereo (TWS): you can connect two identical units to form a stereo pair, thereby expanding the soundstage. The manufacturer states a battery life of up to 12 hours at 50% volume, so expect a shorter duration with louder listening.

Practical aspects: controls, connectivity, and charging

The biggest difference compared to ordinary portable speakers are the three separate rotary controls – bass, treble, and volume. This allows you to fine-tune the sound directly on the device, without needing an app, which will be especially appreciated by listeners of specific genres. The retro body is made of metal and a matte black finish, with a practical handle and a weight of around 3 kg. Charging is handled by a built-in 7.2 V / 5,000 mAh battery with a charging time of approximately 4 hours.

However, two things are fair to mention upfront. A power adapter is not included in the package – the speaker charges via a DC 5 V / 3 A input, so you’ll need to prepare your own wall charger. And via Bluetooth, the speaker supports only the SBC codec, not AAC or aptX. For listening from a phone, this is perfectly sufficient, but don’t look for audiophile-grade wireless quality here. For 1,919 CZK, it’s more of a solid home speaker than a hi-fi solution.

What to watch out for

This is a relatively new model, so a large sample of long-term experience is still lacking. Besides the missing adapter and the basic SBC codec, keep in mind that the stated 12-hour battery life applies to 50% volume – for a party played at full blast, the actual duration will be significantly shorter. Furthermore, the manufacturer states a 6-month lifespan for the built-in battery as a consumable item, which is common practice, but good to know. The speaker also lacks any water resistance certification, so it’s designed more for indoor use than by the pool.

When it doesn’t make sense

If you’re looking for a truly portable, backpack-friendly, and rain-resistant speaker, opt for a smaller, waterproof model instead – this one is designed as a stylish home piece, not an outdoor companion. It also won’t suit people who want the highest quality wireless listening, as it lacks more advanced codecs. And if you don’t mind a stark plastic appearance and are purely focused on the lowest possible price, you’ll find cheaper alternatives. However, for 1,919 CZK, the YENKEE MAMBO L makes sense for anyone who wants a combination of retro design and manually adjustable sound at home.

Verdict: who it’s worth it for

The YENKEE YSP 55BK MAMBO L is a well-executed home speaker with a retro soul – Marshall-style design, metal rotary controls, and a decent 45W output make it a nice addition to a study or living room. Compromises exist (missing adapter, only SBC codec, no water resistance), but these are not hidden flaws, rather a clear focus on home use. For 1,919 CZK with code 2026ALZAEXTRA20 instead of the launch price of 2,999 CZK, it offers a reasonable balance of appearance, controls, and price.

When choosing a speaker, are you guided more by sound, or does the design on the table also play a role?
