Audio-Technica ATH-CKR7TW Review

Airbuds are one of the preferred items when it comes to listening devices today, but it does receive a certain level of ridicule from some. Despite the reactions they’ve been receiving, Airbuds are still a big hit, leaving the premium audio to respond.

Of course, brands like Audio-Technica have responded commercially to this, with their promising ATH-CKR7TW wireless in-ear earphones, marketing an exceptional Japanese lineage.

It’s surely a promising device that has excellent features and specifications, but just how well do these wireless in-ear earphones work? Today, we’re going to look into this product further and see if it’s something worth investing in for all your listening needs. First up, let’s check out what’s inside the box.

Audio-Technica ATH-CKR7TW Review – What’s in the Box?

Our black ATH-CKR7TW wireless earbuds arrived in the usual Audio-Technica package that is clean and simple but with all the details that you’d need to know about the product. The front portion features a huge image of the earpiece while the upper right portion of the box displays the company’s name. On the upper left corner, you’ll find the logo of Audio-Technica while at the bottom of the image is the name of the product and what it is.

You’ll find more details on the side of the package, but it’s mostly about the accessories included inside. There are also instructions printed on the package so you can take a quick look at it before opening the package to see the ATH-CKR7TW.

Once you open the box, you’ll find that the earphones are placed in another box that has a clear plastic cover in front. It’s nice that the company made it this way since you can have a better look at the product even before completely opening the package. Inside, you will find the ATH-CKR7TW itself, eartips with different sizes, a USB cable, a charging case, as well as 3D loops for the earphones. The 3D loops are generally little rubber fins that can be linked or removed from the ATH-CKR7TW to adjust its fit.

The Product

Audio-Technica ATH-CKR7TW Review

The ATH-CKR7TW from Audio-Technica features a unique and distinct style compared to the other wireless earphones that are available in the market. It has a round shape and has a bit of girth which Audio-Technica used to separate the DAC’s electronics from the device’s acoustic chamber. Also, you’ll notice at the top ridge portion of the earphones is the Bluetooth pairing button that also works for playback controls.

Generally, the Audio-Technica ATH-CKR7TW is quite large; yet quite surprisingly, they fit perfectly in the ears without you having to force it in, which is the case in other similar devices. Of course, you can choose the size of the eartips, but sometimes, even the small ones are huge and can be difficult to fit. Anyway, we used the smaller eartips together with the attachable 3D loops or wings.

If you’re expecting to have longer moments of listening to music, you won’t have to worry about any discomfort or pain since the ATH-CKR7TW is made perfectly to provide utmost comfort at all times; this is despite wearing the device for prolonged periods. When it comes to controlling the ATH-CKR7TW, it’s really very simple; the device only features a single button on each side. Speaking of this button, it’s a bit tactile but you can press it easily when wearing the device.

The button on the left side controls the volume; if you want to increase the volume, just press on the volume button once, then twice to lower the volume. The right button functions as the play, answer, or pause button with just a single press; to set the next track, do a double press while a triple press is necessary to go back to the previous track. If you hold the button for four seconds, you’ll switch off the earpiece for that specific side.

When it comes to the case of the ATH-CKR7TW, there is a useful button that displays the battery levels via the LED lights. At the back of this, you’ll find the USB Type-C charging input; and lastly, the button located at the front opens the case’s lid which is durable and sturdy.

What’s nice about this is that you won’t have to worry much about the device popping out of the case since the lid is secure enough to prevent such occurrences. We really liked how securely fit the case is for the earphones since you get that strong, crisp, and solid click when you press the pieces into place. Now after you’ve set the earpieces in place, you’ll just need to close the case to begin the charging process; you can even press down the button located at the center of the case to see how much charge is present.

Using the Product

Before anything else, let’s talk about the fit and make of the device. The ATH-CKR7TW is designed and crafted with precision so you’ll get a build that is just right for your ear. If you need to have the size bigger or smaller, Audio-Technica included different sizes of eartips which are all comfortable when worn even for prolonged hours.

They made it fit adequately so you wouldn’t have to bother with a lot of fiddling just to get the earphones sitting in place – something that we usually have to deal with when it comes to using wireless earbuds. And because of its fit, even with some head movements, there were no instances of the device falling out which was really good.

When it comes to its performance, the ATH-CKR7TW basically has a very clean and loud sound. We noticed that it somehow emphasizes on the high and upper-mids, while the bass and lower-mids are more balanced.

Though don’t worry because it doesn’t mean that the bass isn’t strong and powerful; in fact, its bass response is really good so you’ll still get that thumping bass power that you’d want blending in your music. That said, it hits pretty low, extends adequately, and packs quite a punch; however, the frequency response prefers the higher end.

Sound Quality

For its sound quality, it was excellent and expansive. We tried the earphones with different music genres and we all received rich, nice-sounding music with perfect clarity. The device does not offer any noise-cancelling features, but it sure does block most of the outside sound which was pretty cool

For the ATH-CKR7TW’s soundstage, it is somewhat dependent on how the device fits in your ears. If these are unbalanced in your ears, it gives off a rather wonky-sounding soundstage. That aside, the ATH-CKR7TW has a very solid high with a strong contrast between its lows, light instruments, and rich instruments. The depth of the sounds have lesser contrast that usual due to the increased mid boost that enhances each of the instruments.

Earbuds and Touch Controls

The ATH-CKR7TW’s earbuds utilize the Bluetooth 5.0 wireless technology and includes support for AAC and aptX which was evident while we were listening to music. Even if there were other devices trying to connect to the Bluetooth, we didn’t experience any drop out in the connection which is good.

For the touch controls, all of them were responsive and we were able to easily get used to these. You just need to read the manual to know how many finger taps and gestures are needed for certain functions. When you know what to do, everything will be easy.

The ATH-CKR7TW Earpieces

The right and left earpieces provide you with full control over music playback and calls. For the left piece, it worked excellently and seamlessly when adjusting the volume and it was really easy to press so even when you’re out and walking down the street, you can just press on it lightly and you’re all set. For the right piece, it works just as easily so we were able to easy pause, play, and skip music; it’s also worth noting that answering calls with these buttons was easy so we really liked that.They’re really sensitive so you’ll have to be careful just as well since you might end up making unnecessary calls while using the ATH-CKR7TW.

Overall, the performance of the Audio-Technica ATH-CKR7TW was great and we didn’t have any problems with it. The sounds that it produced were clean, crisp, solid, and powerful, while its bass blended perfectly which gave us that depth we wanted. We also really appreciated that Audio-Technica added a serious thump to their sub and lower-bass registers which, in turn, provides awesome sounds for techno and hip-hop music. For acoustic music, the ATH-CKR7TW delivered clean vocals, smooth guitars and the powerful bass with adequate depth.
