Review on 🎧 ZIHNIC Active Noise Cancelling Headphones - 40 Hours Playtime, Wireless Bluetooth Headset with Deep Bass, Hi-Fi Stereo Sound, Comfortable Earpads for Travel, Home, Office (Black) by Adam Boudreau

I bought these headphones for traveling mainly because of the 45 hours of playback listed. This is an outright deception. Even the box says a maximum time of 35 hours for noise canceling only (NO MUSIC), 30 hours for Bluetooth ONLY (AUDIO but NO noise canceling) and 15 hours for ONLY using noise canceling and Bluetooth. That means the real playback time is only 15 hours. The picture I attach confirms the times I list. Buyer Warning. The sound is decent for what it is, but the blatant lie about the time is just plain sad! Knowing this, I will NOT buy it again.
