Marshall discounted its best headphones by two and a half thousand. They last 100 hours and have a fantastic sound

One hundred hours on a single charge. No, that’s not a typo — Marshall Monitor III A.N.C are available on Alza for 5,984 CZK with code ALZADNY30 and offer battery life that crushes all competition. With ANC enabled, it’s still 70 hours — Bose QuietComfort Ultra offers 24, Sony WH-1000XM5 thirty. A rating of 4.7 out of 5 from 41 reviews and 90% recommendation confirms that these are not just headphones for show — they play excellently and sit comfortably all day.

Quick summary:
✅ Makes sense if you want premium headphones with an iconic design, neutral sound for rock and metal, and don’t want to charge them more than once a week.
⚠️ Consider that ANC is weaker than Sony or Bose — it will suppress noise and ambient sounds, but it won’t completely block out voices around you. And the bass is less pronounced than the competition.
💡 For 5,984 CZK you get 32mm drivers with Signature Sound, Soundstage spatial audio, BT 5.3, 4 microphones, a foldable design with a hard case, and 70–100 hours of battery life.

Sound and Comfort That Lasts

Marshall Signature Sound is neutral with an emphasis on clarity — highs, mids, and lows are balanced without artificial over-bassing. One reviewer summarized it best: “Don’t buy them for hip-hop and techno. They are perfect for rock.” Soundstage technology moves the sound from your head into a virtual space — in the Marshall Bluetooth app, you can set the room size and degree of spatiality. The Dynamic Loudness feature automatically adjusts the frequency curve according to volume.

The PU/TPU leather earcups with a plush headband fit so comfortably that you’ll stop noticing them after a while — users wear them all workday without pain. The foldable design fits into a hard case, which, according to reviewers, finally serves its purpose (no fabric pouch). Control with a single omnidirectional knob on the earcup manages volume, tracks, calls, and ANC — it takes a moment to get used to, but then it works intuitively. Four microphones automatically adapt to ambient noise for clear calls.

What to Expect

ANC is a weaker point. It reliably suppresses low frequencies (airplane hum, air conditioning, city noise), but it doesn’t block out voices around you as effectively as Sony XM5 or Bose QC Ultra. Several reviewers write that thanks to the excellent passive noise isolation of the earcups, this isn’t a major issue — even without ANC, you hear minimal ambient sound. Bluetooth range with obstacles is shorter than some competitors. The included charging cable is absurdly short (approx. 5 cm). And the headphones do not support the LDAC codec, which will disappoint audiophiles.
