Hi Audio-Technica, I have been trying to find out how many microphones are there in each earbud and if they are capable of suppressing background noise during calls outdoors, ie; the caller on the other end to be able to hear your voice clearly in a noisy environment and you don't have to find a quiet place to make phone calls. There is nothing on your website, tried to call the UK number but no response, sent a few emails and no response. Having such a phenomenal battery life is a major benefit for individuals whose work involves making lots of phone calls. Please can you respond here? Appreciate your support.

Thanks for reaching out to us regarding our new CKS50TW earbuds, in particular regarding the noise-cancelling feature. Our CKS50TW earbuds feature one mic per earbud. The active noise-cancelling function, which is mainly effective against noises in the lower frequency range, suppresses background noise during calls. We also recommend selecting the eartips that offer the best sound insulation to maximise the noise-cancelling effect. It's also worth mentioning that they feature a MEMS type microphone, which works particularly well with noise-cancelling technology. We use these daily for calls, both in an office and on-the-go, and find that our colleagues, friends and family barely hear background noises during calls. We hope that helps and we apologise for the delay in responding to your enquiry.

@@AudioTechnicaEMEA thank you for your reply, much appreciated. I have in fact returned the earbuds the next day due to the the unacceptable call quality, people on the other end actually hung up on me due to the background noise outdoors, it was not even a windy day, just a very gentle breeze, the usual road traffic that you can expect in non peak hours of the day. I fell in love with the design, fit the elegant case, especially the battery life which would have made a world of difference for me had the call quality been as good as your reply. I expected nothing short of excellence from audio technica, being world leaders in mic area along with your superior audio engineering excellence. I just wanted to simply keep the earbuds as I absolutely loved everything except the most important thing for me, being calls. I couldn't spend £149.99. Unless you have any alternative options. I have never been so happy about everything else and disappointed about call quality at the same time. Really, most earbuds have atleast 4 mics in total, with some degree of DNN or AI built in with MEMS mics. I have edifier neobuds pro, which eliminate a lot of background road noise, my voice is very clear even in windy conditions, but battery life is horrible. So I was over the moon when I saw your tws. I look forward to hearing from you at your earliest convenience.

Damn... I was ready to order.. but calls are my everyday work so I need best quality. So sad right now 😒

@@7Pe7eR7 indeed I was so disappointed as they were the best fitting amazing earbuds with exceptional battery life

What difference would AAC to aptX make?

Hi Simon, I would actually say these are perfect for higher volumes. They have enough power behind them that they can hold their own better than most other in-ears at this price. Hope that helps!

@@smarthomesounds - Thanks for your speedy reply. Very helpful and very much appreciated! :)

He mentions that in the video towards the end. Yes, buttons do all the things.

If you haven't already made a decision, the these AT's are FAR greater. Not even comparable, I have both.

Hi there, great question. You can adjust the EQ in the Audio-Technica app to bring out the vocals and tone down the bass which will definitely help. If you love everything else about them, I think they're worth a try :)

@@smarthomesounds Thank you for your reply! I will definitely consider this earphones more.

Hi there, they provide you with some different size eartips so you can find a snug fit. I'd recommend trying out the other eartips so that they're comfortable for you long term and unlikely to fall out. Hope that helps!

Need more testing. Anc, transparency and mic. Is the bass really good? Trying to find a perfect ear buds. Looking at liberty 3 pro currently 👀 can u compare this 2 ?

Can the button activate anc? Transparency?

XD XD

@@allbirdsarecats 😂😂 fair enough. Good for music and games not for calls. I went with the Senheiser CX Plus instead and they are excellent for music and good for calls. Didn't need to tune the EQ like I did with my Galaxy Buds Pro. I even compared them side by side with Airpods Pro and they sounded significantly better than Apple's counterpart. Its a shame AudioTechnica's top model is so much more expensive I do like the brand, I've got some over ear ATH-M50X and want one of their microphones. My daily over ears are the Senheiser HD 6XX (I prefer the open backed design and feel more comfortable)

guaranteed 100% i have both and by far ATCKS50TW is way better in terms of noise cancellation. It's an underrated beast.
