**UPDATE Tuesday 29th of March***
They are starting to distort A LOT, and I mean, A LOT the sound. I haven't gone to run with them, I've cared A LOT of them because I loved the quality of sound and the superior active noise cancelling but......what's going on? Are you telling me they work perfectly for just 1 week?
**UPDATE Thursday 31th of March***
Sorry guys but they're not the culprit of distortion, it was my BA500 bluetooth receiver. They still sound fantastic and I'm starting to forget I wear them while I study because I love not hearing the cars outside. My home looks straight into Acton lane, just in front of Acton high School, the pleasure of not hearing any of those cars while I'm studying is worth every single penny. I have paired them now with a pair of better than comply tips, quite cheap from Amazon too, the INAIRS AIR2 tips.
This is a 101 reviewing for this 1st in the list reviewers I so many times see on this products while at the same time I give my own.
1.ANC: When reviewing a noise cancelling headphones people are paying a PLUS for the noise cancellation, therefore it doesn't matter if it's 20 or 300 pounds, they want to know whether it works or not.
THIS PRODUCT: It works.
How properly it works: Well, I went to youtube on the laptop, I found a video of the engine of a plane with high quality sound, then another random one with chatter. The engine is reduce from 100% to 5%. The chatter let's say to 30%. I didn't expect the chatter to be reduced at all. But that's the main reason I bough it. I study in my kitchen and my partner is too noisy, plus the washing machine is here too. This is London, I'm not wasting my time commuting back and forth a proper university library to have some REAL silence.
2.PRICE: Inexpensive. Could you guys please stop comparing them with Bose and saying pointless stuff like "that's what you get for the price" because "that" means nothing. I want to know what I get for the price, I want to know EXACTLY what do I get for the price. This are expensive if we do not consider the ANC. It's a 54 pounds (at least right now) earplug with ANC and no bluetooth, no nothing else than ANC. What you do pay is for the active noise cancellation. I do have tested Bose and it goes in pair with them, not close, in pair. That's a lot to say.
3.SOUND QUALITY: If you want to really be a good reviewer don't play Britney bloody Spears, find this in Spotify: "Antiphon" by "Hidden Orchestra" and put it loud. You want a proper mixture of volume, instruments and effects so you can hear low range, mid range and high pitch. The lows (bass) are realistic, with this I mean they sound as they're supposed to, they're not exaggeratedly amplified as if you were a 16yo with a car trying to impress your mates by creating an artificial earthquake 200 metres around you. The mid range and high pitch sounds are very accurate. If sound quality was measure from 0 to 100% let's say this ones are around 75 to 85% and I don't give a 100% to anyone.
4. BUILT & DURABILITY: There's plenty of room for improvement. They could have done flat cables, the battery compartment could have been instead a USB rechargeable battery. Also the idea of having a wheel to turn up or down the volume is very 20th Century. I would possibly care this earphones much more than I do with others not because of the built but because of their price and functionality. None of my current others have ANC, nor the sound THIS good. Comfort is excellent. This is one of the reasons I went for this, I hate on-ear headphones because mines are Dumbo sized.
5. CONCLUSION: You spend 54 pounds to have real ANC and excellent quality of sound. In that department the product is exactly what you pay for. If you want design you have to give up ANC, if you want bluetooth do as I did, in this same marketplace there's an excellent product called DBPOWER bluetooth receiver. Attach it to this earphones and voila! now you have bluetooth for 8 extra pounds.
I don't like the built at all, as snob as I am I would have gone for flat wires and changed entirely the battery compartment but I have to compromise because this gives me proper ANC. The built is the reason for the 4 stars.
Do not try to buy any ANC headphones that do not state 90% reduction of noise minimum and even in those cases be doubtful and ready to send them back if they're not fit for purpose.
I bought first the 7dayshop bluetooth ones and I ended up VERY VERY VERY disappointed. As I just explained I explicitly wanted this product because of the ANC, if the ANC doesn't work then it doesn't matter how cheap it is it's STILL a waste of money. Those are going back to Amazon ASAP, they aren't fit for purpose. These Audio-Technica are staying with me.
Conclusions: I have wasted 8 hours of my life comparing both reviews in here and out in the internet, video reviews and even one that directly put plenty of headphones on a dummy head with microphones in the ears to compare PROPERLY. You guys have to STEP up reviewing, this is shameful reviewing that most of you are doing and because of you the Amazon's reviews cannot be taken seriously.
