Review on 🎧 Sennheiser CX True Wireless Earbuds - Bluetooth In-Ear Headphones for Music and Calls with Noise Cancellation, Customizable Touch Controls, Enhanced Bass, IPX4 and Long-Lasting 27-Hour Battery Life, Black by Sandro Pierce

I used a Bose QC 35 which is not interchangeable. But now I'm looking for headphones. It's been a few hours since I compared them to the Bose QC and Sport earbuds. Tried many songs. Bass, treble, vocals, voice videos only. It's compelling. Especially with the Smart Balance Equalizer. In any case, I'm deducting a star because the alerts on both headphones are out of sync in most cases. Which worries me if this will be a problem in the future. Also, I'm worried that my ears will hurt from wearing it for hours. A little stuffy in the ears. But I will definitely return all other headphones.
