SoundPEATS Opera 03 / 05 Hi-Res Bluetooth 5.3 Wireless Earbuds with Hi-Fi Stereo Sound Hybrid ANC Support LDAC Audio

The sound quality of the Opera 3 is great. It is way better than my first ear bud I bought many years ago which cost RM50. The bass is tight, solid and controlled. The treble is not overly high and clean. I can clearly distinguish the left and right sound channel. The Soundpeats App has the equalizer which I find useful. The noise cancellation however is a disappointment. It wasn't effective.\n\nThe Opera 3 fitting to my ear is really bad. It could not sit in my ear and I couldn't hear the bass without me pushing the buds into my ear. That is despite me changing the silicon sleeve to the smallest size. The diameter of the outlet is about 50% larger than my old buds. On top of this. the original silicon sleeve design uses a thicker material which further compounded the overall size of the fitting. It was so bad I contemplated returning the product. I had to change the silicon sleeve to an alternative which uses a softer and thinner material. I can say the fitting improved significantly with this modification. I am planning to replace the silicon sleeve to the memory foam type which hopefully improves the fitting further.\n\nBase on the excellent sound quality, I am satisfied with this product.
