Kinera YH623 Review

This week we take a look at YH623 TWS IEM from KINERA which is selling for only $75 USD. 




Disclaimer: HifiGO sent us the $75 KINERA YH623 TWS IEM for this review, free of charge. I only covered the import taxes and fees. All thoughts and experiences with the product are naturally my own. You can find all about it here:


We are continuing our TWS series and reviewing a new TWS every two weeks. There are some really good contenders coming real soon! Follow Headfonia on social networks and stay in the loop.


KINERA is the sub-brand of Yutai Electronics, a Chinese audio company specializing in wide range of audio products. They were established in China’s Guangdong province, over 10 years ago. 

We know KINERA from their expertise in wired In-Ear Monitors. I’ve heard the Idun and Odin in the past and very recently I had the privilege of hearing Nanna. I was amazed by Nanna’s tuning, especially their treble presentation. It’s such a delightful IEM. My colleague Berkhan is going to review the Nanna and that article will be published on Headfonia soon. If you are a treble-lover, I strongly advise you not to miss the Nanna!

Let’s get started with the Kinera YH623!

  • Warranty Card

Packaging & Design

To be honest, the packaging is a bit dull in my opinion and it loudly shouts “Chi-Fi”. Design-wise, I really like the finish and the compactness of the battery box. It is small but Kinera managed to put 400 mAh inside that enclosure and that my friends, is impressive. You can charge the YH623 with the supplied USB-C cable. I really like USB-C so seeing that here is a nice bonus. I hope it will soon be an industry standard.

The case alone can recharge the earphones up to 3 times. It has LEDs on it to let you know about how much juice is remaining. The YH623 also has the ability to auto-pair with your phone as soon as they leave their charging station. It’s not new but it’s cool and easy but we don’t see it a lot in budget oriented TWS earphones such as these. The YH623 has touch controls. Touch controls, in my opinion, are a subjective matter. I personally do not like really them and I had a hard time working with them. I accidentally stopped playback many times during my time with the earphone, I know it’s my own fault but ugh…. A soft push button is a better solution for me but that’s only my take, you may like the YH623’s touch controls. Airpods fans most certainly seem to like it.

The good thing is the YH623 does not feel cheap unlike other contenders at this price point. I quite like the hue of the metallic blue finish. Plus – thanks to the weatherproof design – you can take it wherever you want to go, whether it is raining or snowing. This makes the YH623 a great workout buddy. The amplification level is also impressive and you can pretty much go deaf with these if you would want to. All we can tell you is: listen responsibly!

Comfort & Isolation

The Kinera YH623 is small, compact and light  and the fit is amazing because of that. The seal is really good as well, thanks to the curved housing. The YH623 features a noise reduction technology which is called cVc 8.0. It is not an ACTIVE noise cancellation technology however and its impact is rather small. Some of the online advertisements of this product quote “ANC” but it is simply not advertised anywhere on the box or in the manual.

The isolation is good for a light, small earphone. My girlfriend has really small ears and she used the YH623 without any problems. So people with small ears can go ahead and get this earphone if the sound signature is the right on for you, but more on that after the click on the next page.
