IDeaUSA Wireless Audio Headset with Active Noise Cancellation (ANC) Bluetooth 4.1 - 25 hours Playback – Built-in Microphone Over-Ear Ear Phones/Rotating Mega Bass Anti-Noise AptX-Black for Bluetooth TV Samsung Television PC iPhone7 6S Mobile Phone

Bought because of the praising reviews everywhere, but I'm a little disappointed. They are okay, but I would certainly not call them exceptional.Pairing is fast and without any issues, you'll get clear audible confirmation that the device is on/pairing/connected/etc. Range is definitely up to specification. I experienced a few dropouts, probably due to interference, but nothing annoying.When using the headphones without ANC on, you can hear a faint white noise/hissing when the Bluetooth connection is active but there is no sound playing (for example when you pause a song/video). When the Bluetooth connection becomes inactive (a few seconds after you pause a song/video) the headphones 'pop' before they become silent. This makes them unpleasant to use for browsing/youtube/etc. when you only have sound playing intermittently and also for use on low volume.When you continuously listen to music on a reasonable volume you won't notice this hissing, except for maybe classical music. The hissing and pops are not present when you use the supplied aux cable.Sound quality is good, but not exceptional. I found the lows a bit muddy, low-mids sometimes a bit muffled. They tend to sound better on higher volumes. With ANC on, the sound changes. Lows sound a little more compressed, mids and highs sound more centered. I would say the sound with ANC on is good when the volume is 50% and higher.Don't expect complete silence from the noise cancellation. They do filter out certain noises, but certainly not all. I would say 80-90% of repetitive/continuous low noise will get filtered out, mids and highs, like voices, only 20-50%. For ANC to work you definitely need to set the volume fairly high and ANC also induces an additional white noise which is fairly present on low volumes. In short, the ANC will work on a plane, but not for something like studying.

These headphones work very well over Bluetooth and wired connections, and the ANC,while slightly affecting the music, also works very well to block out lower frequency sounds, such as engine noise. All the buttons are in sensible places, and work over Bluetooth mode. As for comfort, the cups perfectly surround the ear, and are very soft, enabling you to wear them for long periods of time. With ANC turned on, there is a slight pressure in both ears for a while, but when used for long periods of time, your ears get used to it,and it isn't even noticeable. Overall, a decent pair of headphones for this price range, I would defiantly recommend upgrading to these instead of sticking at the price range below, especially as they come with a 1 year warranty. Worth a shot if you want to listen to music in comfort in a noisy place, or even just sit in silence without the noise of your surroundings bothering you.UPDATE: Had them for about 20 days, and the bass in the left ear has dissapeared, also meaning the noise cancelling no longer works in that ear. I am contacting the seller to see if anything can be done, or if I can get a replacement.FURTHER UPDATE: Now, had them a full month, and no sound in left ear at all unless ANC turned on, but ANC no longer cancels out noise, and builds up uneven pressure in each ear making them feel odd to wear. After trying to return the item (and my Bluetooth speakers I got for free as an add on item) through amazon, the "30 days money back guarantee" tried to refund me £52 (i had paid £69.99 for the items). not sure i got a faulty pair, but i was told it was very unusual for problems to arise with these headphones by the customer service I contacted...

BUILD QUALITY - They feel really well built, with quite flexible but sturdy structure and overall really nice finish to it.COMFORT - padding is amazing. Very soft pads and it completely covers your ears. Clamping is average, but thats what it makes comfortable I guess, as it doesn't push hard on your head. However, I would not recommend these for people with small heads. I have bigger than average size head and I use on minimal sizing and it just fits me.CONTROLS - although some reviews said that controls are a bit awkwardly positioned, I didnt find it a problem. I could comfortably switch songs, change volume etc.BLUETOOTH - pairing was easy. Connection mostly is stable (especially if you are not moving). If you walk, then there are occasional drop outs for like 0.1s but they are not too frequent, nothing what would deteriorate your listening experience.ANC - This is my first ANC experience. But I can say that they provide alright noise cancellation. It shuts off most of the rumble noises ( I use underground a lot and it really helps), as well chatter around you (for example in the office). However, not as great as you would probably want to. If there are mid to higher pitched noises, like announcements on the trains or screech of train wheels, accelerating car passing by you can still hear it. But there is significant difference between off/on, in favour of ON. Sounds gets a bit "compressed" as some reviewers said, but if you turn on volume 1-2 bars higher after switching to ANC, then actually sound is more crisp, and bass is still good.SOUND QUALITY - it is well balanced, cannot really complain. Treble, mids, bass are all there. Even with ANC I really enjoy my music a lot. I listen all different genres, from classic to metal to trap, and it handles everything like a champ.BATTERY - They came pre-charged but not fully, and they lasted me for a week currently. I listen to music while commuting and at the office a bit, which account for up to 1.5 - 2 hours a day. I am yet to test them on full charge.WIRED - Today, battery died while I was getting back home and I just switched to a wired option and enjoyed my music further. No real difference in sound quality with wired or not. Both excellent.OVERALL - for 70 pounds I can easily recommend these. For 99% who are casual listeners like me, you will really enjoy this pair. They feel really nice and look really nice and provide excellent listening experience.
