Review on Sennheiser CX 300S White In-Ear Headphones 🎧 with One-Button Smart Remote for Superior Sound Quality by Rachel Brennan

I tested the headphones with a LG Dynasty phone, a Moto 4e phone and an iPad Air 2 with jack adapter and the microphone was pretty bad on all my devices. The sound is quite good for listening to music and voices, but for using the microphone for phone calls and recording, the volume was quite low and background noise was even louder. I've tested the sound with various recording and social media apps but still nothing good. I bought it mainly for communication and was very disappointed with the price. I have too many headphones from other brands for music and I just wanted a good set with a microphone, but it didn't suit me. It's just an expensive headphone with no microphone function. My other Bluetooth devices with a mic worked surprisingly better than this one.
