The new Audio-Technica ATH-CKS50TW truly wireless in-ear just keeps on playing, up to 20 hours on a full battery to be exact.
The downside of many true wireless in-ears is that they all too often offer miserable playing time on a battery charge. Somewhere after 4 to 7 hours it usually gets rather silent. Not so with the Audio-Technica ATH-CKS50TW! Once fully charged, you can listen for 20 hours straight (with the ANC enabled, a still impressive 15 hours of playing time). And if even that isn’t enough, the included charging case gives you the option of listening for a total of 50 hours independent of mains power. The case contains a battery too, that can be used to charge the earphones on the go.
If you are in a hurry, just 10 minutes of charging is enough for another 90 minutes of playing time. The Audio-Technica ATH-CKS50TW is also certified for Sony 360 Reality Audio, and you can pair with more than one source at the same time (multipoint). A nice touch is the IPX4 water resistance. Finally, the time when capable real in-ears were hefty on the price seems behind us: for the ATH-CKS50TW you pay only €169.
