Waterproof speaker for 562 CZK. This one from Alza is great for travel and lasts up to 8 hours

Waterproof Bluetooth speakers with reasonable power usually cost over a thousand. However, you can currently get the AlzaPower Quest 10 for 562 CZK with the discount code ALZADNY25, which is a quarter less than the regular price. For less than six hundred crowns, you get a speaker that can survive a fall into water and play for up to 8 hours.

Quick summary:
✅ Makes sense if you are looking for a durable speaker for trips, by the pool, or in the shower at a reasonable price.
⚠️ Consider if you expect a full-fledged FM radio – the speaker can only tune to 6 fixed frequencies.
💡 For 562 CZK you get IPX7 water resistance, 8 hours of battery life, Bluetooth 5.4, and the option to pair two speakers for stereo – that’s a solid offer in this price category.

Why this speaker is interesting

This speaker from AlzaPower targets those who want music on the go without fear of water. With IPX7 certification, it can survive immersion in water up to 1 meter deep for 30 minutes – so a shower, rain, or a fall into the pool won’t destroy it. Compact dimensions of 79 × 125 × 79 mm and a practical loop allow for easy attachment to a backpack.

Sound and Connectivity

The 10 W power with a frequency range of 100–20,000 Hz matches the speaker’s size. Bluetooth 5.4 ensures a stable connection up to 10 meters away. The TWS (True Wireless Stereo) function allows pairing two Quest 10 speakers for spatial stereo sound – each then plays one channel.

In addition to Bluetooth, you can connect devices via the AUX connector or play music directly from a flash drive (up to 32 GB) via the USB-A port. The speaker supports MP3, WAV, WMA, APE, and FLAC formats. An FM radio is also available, but beware – it only works on 6 fixed frequencies (87.8; 89.8; 99.1; 104.3; 105.7 and 106.2 MHz), which may be limiting for some users.

Practical aspects: battery life, controls, in the box

The 3,200 mAh battery provides a battery life of up to 8 hours on a single charge – some users in reviews even report significantly longer. Charging via USB-C takes approximately 3 hours, and the cable is included in the package. The automatic shutdown function after 10 minutes of inactivity saves battery.

The LED backlight on the side displays the volume level and charging status, while the backlit logo illuminates on the top. Control is done via buttons on the speaker body. The integrated microphone allows for hands-free calling – you can answer or reject a call with the Play button.

What users say

On Alza, the speaker has a rating of 4.4 out of 5 (29 ratings) and 79% of customers recommend it. Over 1,000 units have already been sold with a low complaint rate of 1.26%. Users most often praise the price/performance ratio, water resistance, and battery life. One reviewer writes: “The speaker plays quite decently loud. I would compare it to speakers about 300–500 more expensive.”

Critical voices appear regarding several aspects. The biggest problem is the FM radio with only 6 fixed frequencies – for example, Radio 1 in Prague cannot be tuned. Some users rate the sound as “muffled” or too quiet, even though others praise it. Voice notifications can be annoying, and the backlight must be turned off after each power-on. Important note: some phones may recognize the speaker as headphones and limit the volume – in such a case, it is necessary to change the device type to “speaker” in the Bluetooth settings.

If you need higher power, there is also the Quest 20 for 899 CZK or the Quest 40 for 1,699 CZK. Other discounted speakers and audio accessories can be found in the current Alza Days.

Verdict: who it’s worth it for

If you are looking for a durable speaker for trips or by the water at a reasonable price, this discount is definitely interesting. For 562 CZK you get IPX7 water resistance, 8 hours of battery life, Bluetooth 5.4 with TWS function, and the option to play from a flash drive. On the other hand, if a full-fledged FM radio is crucial for you or you expect audiophile sound quality, it’s worth considering more expensive alternatives.
