Bests & Worsts Reviews from Amazon

I bought these headphones for travel mostly due to the listed 45H of playtime. That is a flat-out deception. Even on the box the maximum time listed is 35 hours for noise cancelling function only (NO MUSIC), 30 hours if using ONLY bluetooth (SOUND but NO Noise cancelling), and 15 hours ONLY if using both noise cancelling and bluetooth. This means the real playtime is only 15 hours. The image I'm attaching validates the times I list. Buyer beware. The sound is decent for what it is but the clear lie about the time is just sad!!! Knowing this, I would NOT buy again. UPDATING REVIEW: After about 6 months of use, the headphones will not charge past 40%. I even left them to charge for 5 days with no more charge. When the headphones get down to 10%, there is a message EVERY 8 SECONDS (I counted) saying "DISCHARGING". So, I am changing my review from 2 to 1 star based on the fail and the nagging message!
