Review on 🎧 CCA CA4 Dual Driver HiFi In-Ear Monitors | 1DD + 1BA Earphones | Audio Stereo Earbuds/Headphones with Dynamic & Balanced Armature Drivers | No Mic | Black by Brandi Patel

According to Revain and the brand inlay, this model had the best bass response. They have almost NO BASS! Too bad that high frequencies are good for their price but useless for music. The supplement had a very poor English translation that referred to "burning" which is a myth. If this isn't a defective set, then don't believe the reviews about good bass. It does not exist.
