F2 - Update 4/7 - It broke after 18 months, I will try Cowin, TaoTronics, or a new brand
October 16, 2017
Update 4/7/19 I contacted Bluedio and the reply was to take the headphones to a repair job, because they were out of warranty (12 months). They did offer to sell me another headphone at a $10 discount. At this point , my confidence on the quality of their products is gone. Happily Amazon has several offerings, I will give a try to Cowin, TaoTronics or Avant tree that are at the same price point for similar product.
Update 4/4/19 The headphone just broke apart 18 months after I bought, this headphones were used very little, only when I travel because at home I used the Bluedio Victory. So at the most this headphones had been used less than 6 months. Very disappointed. I already bought 4 headphones from Bluedio (I paid for them all) I gave away the T4S, and keep the F2 because of the sound, ANC and look, but now is broken
I was not able to find any information on warranty, so I sent today an email to Bluedio, will see what happened. I will post if I get any resolution
Original: This is the second headphone (the other is the T4S) set that I got from Bluedio. I paid for both my sets
Understanding that this is a $50 headphone and not a Bose, then the performance of the headphones is very good. The sound is excellent with good bass, mid and high, they are lighter than the T4S and hold in my head better. The ANC is also good, I just used them in a 2 hours flight in a regional jet and cut the noise significantly, not like a Bose but very well for this price range.
Two weak point are 1) when they are in wired mode, the headphones power off and you lose the controls located on the headset (volumes, next song, pause), 2) when the ANC is on, it deteriorates the sound (It happens with all ANC headphones)
All along I am very happy with this set, I plan to keep it and continue using it.
As far as you understand this is not a $300 dollar product, I would recommend this headphone
