Parrot Zik 2.0 Wireless Noise Cancelling Headphones

FINAL UPDATE 11/27:I am returning both headphones and going with a different brand/model at this time.Upon further examination of both headphones I determined the internal aluminum is actually snapping. I don't treat my products roughly and I certainly don't treat $400 headphones roughly (the second pair within minutes of ownership). I am blown away at how easy this aluminum snaps. This won't be an issue for any of you with smaller heads, but for those of you with larger heads just be very careful with extending the left can (the right doesn't appear to have the same problem for me).For the record, I contacted Parrot as well and they responded same day and also offered to repair or replace them, but after 24 hours of reflection with a second broken pair I just cannot justify the $400 price tag with future risk at this point.Bottom Line: Yes I would buy these headphones again after a redesign to fix what appears to be a design weakness and adjustments to accommodate larger heads. The sound was fantastic, the features were outstanding, and companies that think and push this way are the ones that deserve our money. Unfortunately in this situation I just can't make it happen so I am moving on.-----------------------------------------------UPDATE 11/26:I received a second Zik 2.0 replacement from Amazon and it also exhibits the same defect with the left headphone. The "stop" that prevents you from extending the headphones too far does not work properly and the headphone extends past the limit with ease. Once you extend it past this limit the internal ratchet system is broken for good. The right headphone does not appear to have this same problem. I have adjusted my rating to 2 stars until Parrot resolves this issue.I do think the audio quality with these headphones is superb after many days of use. Although the sizing is way too small to be practical for users with head size above average, I do think those users that fall within the limited sizing range of these headphones will have a very comfortable listening experience. I am right at the edge of sizing (read below) and I still believe these headphones are more comfortable than Beats Studio Wireless, the noise cancellation is better, and the audio quality is night and day difference.The sensors are still way too sensitive and this has been confirmed after several days of use now across two different units. In fact, I must have crazy active jaws because the act of eating food with these things on was actually pausing music via the presence sensor (i.e. thinks I'm pulling the headphones off so pauses music). I would really like to see Parrot update the app to allow users to customize sensitivity (i.e. High, Medium, Low).-----------------------------------------------Negatives:1) CAUTION as other users have mentioned these things are made for small heads. I returned a pair of Beats Studio Wireless for the new Zik 2.0, and the Zik's BARELY fit my head. Technically they don't fit (I have to tip them forward). I don't know what Parrot was thinking here - I was only 1/2 through the range on the Studios. So be warned if you have a medium or large head these might be a very tight fit.2) My Zik 2.0 arrived with a broken left headphone adjustment too...it doesn't "click" like it should each setting and will actually pull out of the head band. Luckily Amazon is easy to exchange with so I'm going to try a new pair and see how that works, but makes me a little concerned about Parrot's QC.3) I echo other comments in that the sensors on this are way too sensitive. It has been pretty annoying in that you go to adjust the headphones and music stops...or barely touch the side and you've screwed with volume, paused track, etc. I wish they gave the user the option to dial down the sensitivity.Positives:1) Audio quality is way better than the Beats Studio Wireless. These aren't going to be reference level audio, but I think they are the best bluetooth headset that I've heard so far. I think the EQ and customizations are really easy to use to tweak the sound as you like too.2) Despite the terribly small sizing range, the ear cups are nice in that they fit around my ears just fine. The Beats Studio Wireless sat on my ears in parts and caused some raw spots with extended listening.3) Lightweight, compact design, and look nice. I think they are a sharp headset and don't feel bulky at all.4) Noise cancellation is superb. Bose might be a little better, but the Bose bluetooth headphones don't have the active noise cancellation and the ones that do require a cord. So I think Parrot wins here (night and day better than Beats Studio noise cancellation).Overall I will probably keep these because they are the best option for me in the $400 range with bluetooth and ANC, but if there was better competition I would probably not keep these.P.S. Parrot if you read this please get your people running the twitter account to start responding. In the days leading up I saw many people asking about release date, availability, etc and you IGNORED them. Not cool.
