These earphones by SoundPeats sport a dual driver system which works to serve up relatively balanced sound, with equally good highs, mids and lows. No equalizer was needed to create a good sound experience as the default sound profile was fantastic as is. However, due to housing two drivers within each earphone, they are quite large in size and can stick out of the ears quite substantially. They also, due to their weight tend to fall out more easily than other in ear earbud style earphones, however not as much as the airpod style typically do. The material and construction is amazing, with both the earphones and the case sporting a soft touch plastic material that feels great to touch, and also adds a non slip component. Qualcomm apt X codec support and Bluetooth 5.0 adds a fantastic touch to the connectivity and sound quality that is seldom seen at this price range. The battery life is also very good, lasting a whole week of light-moderate usage without a single charge. Noise cancellation exists only as passive, however due to the good seal they provided, at least for me, they were more than good enough for most environments. Overall, at the price point, these earphones are an absolute no brainier, and you will not be dissapointed with the purchase.
