For little money, a lot of music: Alza discounted its ANC headphones below 900 CZK, they have great features and excellent ratings

Alza also has a range of affordable wireless headphones in its product portfolio, which offer an excellent price-performance ratio when purchased on sale. The top model of the AlzaPower Boost ULTRA ANC series now costs only 899 CZK with the ALZADNY40 code – a price level it last had in January. Users, meanwhile, praise them.

Quick summary:
✅ Makes sense if you are looking for ANC headphones under a thousand with an LDAC codec, multipoint connection, and longer battery life than most cheap competitors.
⚠️ Consider if you want volume control directly on the headphones (missing), an app with an equalizer (none), or really strong ANC for airplanes.
💡 For 899 CZK, this is one of the best offers in this price range – within the regular price of 1,499 CZK, the ratios are a bit different, it makes sense to buy with a discount.

Why these headphones are interesting

AlzaPower Boost ULTRA ANC belongs to the category of affordable ANC headphones under a thousand, where they compete with, for example, Huawei FreeBuds SE 4 ANC, Redmi Buds 6 Pro, or cheaper Philips models. What is specific about them is that they combine features that you usually don’t get together at this price – specifically, support for the higher LDAC codec, multipoint connection (two devices simultaneously), and 12mm drivers.

The second argument is the above-standard 36-month warranty, which is exceptional for TWS headphones at this price – you usually get 24 months. This is especially relevant because headphone batteries are consumables and their capacity gradually decreases. AlzaPower also offers immediate replacement for a new unit at branches in case of a defect, which simplifies any warranty claims.

Key parameters explained in plain language

Inside each earbud works a 12mm dynamic neodymium driver – larger than most cheap headphones, where the standard is 6–10 mm. This theoretically impacts bass power and overall dynamics. In practice, reviewers describe two extremes: out of the box, the sound seems over-bassy and sometimes unpleasant, but after adjusting the equalizer (e.g., in Spotify or PowerAmp), it transforms into a genuinely good sound for this price. However, the headphones do not have their own app with an equalizer – you have to make do with the equalizer in the app you are listening from.

On the wireless side, you get Bluetooth 5.3 with support for AAC, SBC, and LDAC codecs. LDAC is relevant for Android users who want to transmit higher quality audio – however, with active LDAC, you cannot use multipoint connection (two devices simultaneously), it’s either/or. The headphones have IPX4 certification against sweat and splashing water, so they can withstand workouts and light rain.

Hybrid ANC works with six microphones and states noise cancellation up to –46 dB in its parameters. Real-world effectiveness, according to reviews, is rather average to good – sufficient for public transport, cafes, and offices, but for airplanes or really noisy environments, you should pay extra. It also features a transparent mode and a low-latency gaming mode.

Practical aspects: battery life, controls, code

Battery life is one of the main strengths. The headphones themselves can last 8.5 hours without ANC, and a full 34 hours with the case of continuous listening (manufacturer’s data). Charging both the headphones and the case takes approximately 2 hours via USB-C. The headphones weigh only 4.5 g – you essentially don’t feel them in your ears. Reviewers repeatedly praise their comfort during longer listening sessions and the fact that you can fall asleep with them without issue.

Control works via touchpads on the earbuds: double tap for pause/answer call, triple tap to skip track, hold for 2 seconds to switch ANC. Key criticism across reviews: volume control is missing directly on the headphones – you have to adjust it from your phone or watch. For some, a triviality, for others, a deal-breaker. A few reviewers also mention that the touchpads sometimes act inaccurately, so a tap might be missed.

The price of 899 CZK is valid only after entering the code ALZADNY40 in the cart. Without the code, the “super price” remains 1,499 CZK. The discount code is part of the Alza Days campaign, which is time-limited, and the offer may change based on stock availability. The headphones last appeared in a similar promotion in January; otherwise, the lowest prices outside the biggest campaigns end around 1,100 CZK.

What users say

On Alza, the headphones have a rating of 4.6 out of 5 (68 ratings), 90% of customers recommend them, and 42 people wrote detailed text reviews. This is a relatively large sample, from which a fairly consistent picture emerges. The complaint rate is 3.16%.

The most common praises are price/performance ratio, battery life, comfortable wear, and sound quality after equalizer adjustment. Reviewers who switched from more expensive models like Sony WF-1000XM3 or AirPods Pro describe the sound difference as noticeable, but not directly proportional to the price difference. Several reviewers explicitly mention that for a price under 900 CZK, these are the best ANC headphones currently available.

Critical voices, however, are systematically repeated and are worth taking seriously. Firstly – the default sound setting is over-bassy and, without equalizer adjustment, sounds unpleasant to some. Secondly – ANC quality is inconsistent: some reviewers describe the cancellation as comparable to AirPods Pro, while others feel that ANC “barely works” and is paradoxically worse than with the cheaper AlzaPower Boost Pro siblings. These differences may be related to the earbud’s seal in the ear – ANC does not work with poor fit.

Thirdly – the quality of the case and overall build. A few reviewers mention that the plastic case feels cheap, is difficult to open with one hand, and for one reviewer, even the reset and power-off of the headphones after insertion did not work (resolved by replacement). If this particular model didn’t appeal to you, but you’re looking for affordable headphones on sale, you can also check out the current Alza Days, where other discounted models from Huawei, Xiaomi, JBL, or Philips appear.

When it doesn’t make sense

The discount is significant, but these headphones are not for everyone. If you need volume control directly on the headphones, you’ll run into an issue – and headphones at this price point, like the Huawei FreeBuds SE 4 (after a firmware update), already offer it today. A second reason to consider a different model: if you want an app for more precise sound adjustment, equalizer, and custom gestures, AlzaPower does not offer one. Competitors like Sony, JBL, or Soundcore typically address this.

And thirdly: if you need really strong ANC for airplanes or extremely noisy offices, the noise cancellation effectiveness rating for Boost ULTRA ANC is inconsistent. Full-fledged alternatives are only more expensive models from Sony, Bose, or Apple, priced at 4–8 thousand CZK.

Verdict: who it’s worth it for

If you are looking for ANC headphones under 1,000 CZK with an LDAC codec, multipoint connection, and longer battery life, and you catch the price of 899 CZK with code ALZADNY40, this is a price that only appears occasionally and is currently available. The drop from the usual 1,499 CZK is significant, and the rating of 4.6 out of 5 from 68 customers indicates that the vast majority of owners are satisfied with their purchase. Conversely, if you need volume control directly on the earbuds, a full-featured app with an equalizer, or top-tier ANC, it’s worth considering a different model – usually for more money.

What is decisive for you in headphones under a thousand – battery life, ANC, or perhaps support for higher codecs like LDAC?
