Top-tier Bose QC Ultra Earbuds (2nd gen) dropped to a minimum price! They have phenomenal ANC and great sound

If someone asks you for a recommendation for top-tier noise-cancelling in-ear headphones, the answer can be quite simple — Bose QC Ultra Earbuds 2nd generation are on Alza for 6,164 CZK after entering code AUDIOVIDEOTYDNY10. From the original 7,690 CZK, you save over fifteen hundred crowns on headphones that, according to users, have no real competition in suppressing ambient noise. One reviewer aptly summarized it: “Unrivaled ANC, only foam earplugs can reliably block out ambient noise like this.”

Quick Summary:
✅ Makes sense if you want the best available ANC in an in-ear design, quality sound, and multipoint connection to two devices simultaneously.
⚠️ Consider if even minimal digital noise in absolute silence bothers you — several users report a subtle background hum when ANC is on. And the Bose app could be clearer.
💡 For 6,164 CZK you get ANC with three modes, Immersive Audio spatial sound, Bluetooth 5.3, wireless charging case, and 24h total battery life

ANC that lives up to its reputation

Bose v potlačení hluku tradičně exceluje a druhá generace Ultra Earbuds na to navazuje. K dispozici jsou tři režimy ANC: Quiet pro maximální izolaci, Aware pro propouštění okolních zvuků a nový ActiveSense, který automaticky tlumí náhlé hlasité zvuky — sirény, troubení, padající předměty. Technologie CustomTune při každém nasazení analyzuje tvar vašich ušních kanálků a kalibruje zvuk i ANC na míru.

Users repeatedly confirm that these Bose are unrivaled in dampening low frequencies and human voices. One reviewer explicitly states that the ANC is significantly better than the latest AirPods Pro, by “a whole horse’s length.” A slight catch: higher frequencies like keyboard or mouse clicks are not dampened as effectively by the headphones — one user notes that they are not reliable in an office setting.

Sound, comfort, and what’s new

Sonically, the Ultra Earbuds are at the peak of what you expect from Bluetooth in-ear headphones. aptX Adaptive support ensures high-quality streaming, while the Immersive Audio feature expands the soundstage into virtual surround — there’s even a special Cinema mode for movies. By default, users find the headphones unnecessarily bass-heavy, but the three-band EQ in the app easily resolves this.

Ergonomics are a strong point. The package includes three sizes of ear tips and three sizes of stability bands, which can be combined freely. You can test the result directly in the Bose app — the headphones stay put even when running or at the gym. The weight is 14.2 grams per earbud, and IPX4 certification covers sweat and rain.

Compared to the previous generation, wireless charging for the case (finally), multipoint Bluetooth 5.3 for simultaneous connection to both phone and laptop, and improved AI noise cancellation during calls have been added. The case is of higher quality and more presentable.

What to watch out for

Battery life is 6 hours on a single charge (4 hours with Immersive Audio), with the case adding another 18 hours. Twenty minutes in the case will provide enough power for 2 hours of listening. The touch controls on the earbuds are sensitive — several users mention accidentally skipping tracks when adjusting their position in the ear. It takes some getting used to.

The return rate on Alza is 3.17%, which is slightly higher than other products in this overview. One user describes a persistent digital hum when ANC is on — she tried two different units with the same result, but other reviewers do not report this issue. The Bose app works reliably, but its design is described by some as “chaotic and unintuitive.”

Verdict

The Bose QC Ultra Earbuds 2nd generation for 6,164 CZK are headphones for those who want the absolute best in noise cancellation and are unwilling to compromise on sound. Multipoint, wireless charging, and sophisticated ergonomics with interchangeable tips complete a package that has few rivals in this category.

Do you use ANC headphones every day, or do you only put them on for travel and noisy environments?
