I bought these in Nov 2018 along with three other pairs of other headphones All are over the ear, noise cancelling, wired or wireless. The others arehttps://www.amazon.com/gp/product/B07DW39N4T/ref=ppx_yo_dt_b_asin_title_o03_s02?ie=UTF8&psc=1https://www.amazon.com/gp/product/B077YG22Y9/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1https://www.amazon.com/gp/product/B01IEHIMLY/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1Of the four I kept the IdeaPlay for myself and gave the Hiearcool L2 to my wife. At the time I made some notes about each pair. These are my notes:Most important to me were sound quality, comfort and noise cancellation. The IdeaPlay sound quality was extremely good (probably not as good as top tier Bose, Sony, et.al., but quite good overall) It is a little bass heavy, but clean sounding. Mids and highs are very clear. Overall the sound is well balanced. Of the four headphones I bought, this pair is the only one that the sound was exactly the same whether the ANC was on or off. The others all sounded different depending upon whether the ANC was on or off. The sound on the IdeaPlay was also the same whether using Bluetooth or the cable. It has more volume using BT. These get loud! Comfort is the best of the bunch, followed closely by the Hiearcool. The ear holes are 2.4x1.5 inches and rectangular (not round or oval). They weigh 11 oz. The noise cancelling on the IdeaPlay is not as strong as on the others, but still reasonably good. I use these headphones when using the lawnmower or especially the leaf blower and will use them on the plane if I travel again and they are good for long time periods and block droning sounds well. The controls are pretty logical and better than on the other three pair. I have also found they are very good for phone calls. The other person on the call does not know I am using a headphone and they are very clear to me. Finally, I have downloaded an equalizer program (Equalizer APO) to my desktop (Windows 10) which allows tremendous customization of the sound. With that program engaged these headphones sound incredible. I just need to find the same program for my phone (Android). This program would probably overcome the deficiencies in any headphone.The Hiearcool L2 was fairly comfortable, with cushy large earpieces. Sound was generally very good, though a little bass heavy but not muddy or boomy. Mids and highs come through pretty well although the bass is stronger. These sound better with the ANC on. The sound field broadens, it gets a little louder and bass gets even heavier but still clean. Mediocre controls - most of the buttons feel the same to your finger tips. The upper volume button turns the volume down (goofy). ANC is good - I only tested them by cranking up the home stereo and not with a leaf blower or on a plane. They weigh between 10.5 and 11 ounces.The Cowin headphones had thumpy bass (worse than the two above but better than the next) but the sound is very affected by the ANC. With ANC on is sounds much better. Voices are pretty clear, so are cymbals. It was very musical and sounded a lot like my home stereo (lots of old Harman Kardon and B&W) which is a good thing. Overall a good sound with ANC on and easy to live with. However, this headphone has to have the ANC on all the time for decent sound. Controls are stupid - the top button turns the volume down. Also you have to press and hold the volume button to turn it up/down so it is easy to turn it up/down too much. I could not get the ANC to work when using the wired cable - it cut off every time. Remember where I said the sound quality was good only when ANC was on? If you've got a long flight be sure you charge the battery in advance because you don't want to listen to this headphone while wired (sound quality suffers) and the ANC wouldn't work. Not as comfortable as the first two. A bit heavier and the ear cups are firmer. They noticeably pressed on my glasses. Overall the Cowin had very good sound quality with the ANC on and the ANC was also good. Two strikes are the illogical controls and the uncomfortable fit.Finally, the PAWW phones were the worst of the bunch and the most expensive. The bass was thumpy and became worse with ANC on. Mids were hard to hear. With ANC on the sound field made you think a switch was set to Mono and not Stereo. ANC would be usable only if you were not listening to any music. The controls were logical and the earpieces were more comfortable than the Cowin. Between the highest price and the poor sound quality of music with ANC on, I quickly took these out of consideration.One final note - recently I saw a pair of Sony headphones (WH-CH700N) on sale at Best Buy and bought them on impulse. They were about $120. I was completely underwhelmed by the sound and could not get them to sound good no matter what I listened to. There is a dedicated app you can download to your iPhone (I was unsure of whether I could download it to my Windows or Android stuff) that might make it better but I just couldn't see the point of having to do that to get it to sound okay. As it stood right out of the box I had no interest in them and quickly sent them back. I would buy the IdeaPlay every time over the Sony. And probably the Hiearcool over the Sony too. Both of them sound good right out of the box, have no fatal flaws and beat the Sony on price too.Overall, a decent set of headphones with good sound quality, economical materials, reasonable build, and reliable bluetooth pairing (at least with Apple devices). Also, they're very comfortable to wear, have an attractive appearance, and, the included accessories and case are nice additions. However, for the price, the active noise cancellation could be improved.Cons/Info to keep in mind: The active noise cancellation is okay, but not great. I recently used these headphones on two separate flights, one approximately 1.5 hours, the other, just under 4 hours. Both flights were roundtrip and on Delta 737's. For all flights, I had a window seat near or on the airplane wing, directly across from the engines. I noticed while wearing the headphones that while they did dampen the engine noise, if I pressed the headphones slightly tighter on my ears, they performed much better. Of course, that has more to do with the passive noise cancellation effect of the ear pads compressed against my ears, but, making the headphones more snug could help improve the noise cancellation overall. Additionally, I noticed while wearing the headphones on both flights that sometimes when I would turn my head in a non-looking-forward-direction, the noise cancellation quality would actually change and be slightly better when angled directly at the engines. I presume this is due to the microphone/noise cancellation hardware being in a better ambient sound proximity position, thus countering the engine noise more effectively. Keeping one's head turned for the duration of even a short flight isn't comfortable, however. I will say, though, that these headphones are a better option than just using your smartphone ear-buds (i.e., iPhone ear-buds).Overall impression: A good set of wireless headphones, but have realistic expectations for what you're getting. I'm happy with my purchase, but these are not Boise quality noise cancelling headphones, nor do they have as impressive of sound quality. And, to be fair, they're not marketed as such either and shouldn't be held to the same standard for comparison if that is what you're expecting/hoping. Personally, I believe $65 to $70 is the appropriate price range for these, but I wouldn't pay any more than the current MRSP ($79.99) unless the active noise cancelling technology is improved. The claim from the manufacturer that these reduce outside noise by 85% may be true of some forms of ambient noise, but, in my non-scientifically tested experience so far, at least for airplane engine noise on major commercial flights, that number is probably closer to a range of 60 to 70%. I could be wrong, as I'm not a sound expert or engineer, but my impression is that more design consideration went into the style, appearance, and build (sound quality) of these headphones, and less development into the noise cancellation hardware/technology. Hopefully future versions will focus more on the latter, and, if so, they would be a much higher quality product with wide appeal.This over ear headset is for my little girl,she insisted to buy this when she looked through Amazon. She said it looks very cool and different from other brands,and the price is affordable.The picture is visually appealing, and the headphone looks much more stylish actually. It is big but not clumsyFirst I didn't know how to turn it on, thankfully there is manual in the box which detail everything we need to master. It really give me the luxury feel when I hold it, don't mention it comes in a nice carry box.It is adjustable and foldable ,which make it easy to carry and fits every one of head.The ear muff is soft and comfy, it wouldn't hurt even we wear the headset for a long time.The sound quality is crystal good and it deliver a lot of bass. When we turn the active noise canceling on, all we have is the music , there is nothing can intrude the world. We are so soak into it and enjoy.The Bluetooth connection is seamless, it can pair and be easy to pick up any wireless enable device.The battery lifetime is impressed too,it really can play more than 12hours. We still can use aux port cable even we ran out of battery, it's kind of convenient when we are out .It is great experience to implore this headphone. My girl told me I won't regret to buy it ,and now it proved her choice is smart. I am so glad that my girl love it and she is so happy to own one!
