Opera Factory OS1 Pro ReviewIntroduction: Let's start with the unboxing. The unboxing experience here is frankly perfect. I expected a lot less from the $26 IEM. But the unboxing experience here really blew me away. OS1 Pro comes in a graffiti-style box. After opening, you will be shown the IEM itself as well as the attachments (S, M, L) and cables that came with it. The design of the box and the unpacking process are very well thought out. Huge respect to Opera Factory for their efforts in designing the box. Now let's get to the sound. The overall sound signature here is warm, dark and bassy. The OS1 Pro is a bass-focused IEM that sounds great with today's music. Music like pop, rap, hip-hop, RnB, electro, EDM and club music will sound great with OS1 Pro. Bass is punchy and fat, sub-bass is boomy and well-extended, mids are warm and forward, vocal presence is good and forward, and highs are soft. The OS1 Pro isn't perfect, but it is for the price it's sold for. , it is very difficult to find bugs. Here are the pros and cons of OS1 Pro.Pros β : - EXCELLENT thoughtful unboxing - Great bass. Warm, thick and punchy bass - Excellent subwoofer presence and hum - Good imaging for the price. Decent overall picture - Good soundstage for the price - Soundstage is wide and tall - Good vocal presence. Cons β: - Noticeable mid-bass leakage - Lack of treble extension and brilliance - Instrument separation could be better In conclusion, I would say that for the price that the OS1 Pro is sold for, the OS1 Pro is an easy task for bass lovers and people who looking for a good bass on a budget. Its thick, high-quality, punchy bass combined with good imagination and soundstage makes the OS1 Pro an easy recommendation for me. If you've been thinking about buying OS1 Pro, just do it. It's a no-brainer in my opinion :) Oh, and besides, the design of the OS1 Pro shell is beautiful. Check out the photos to see for yourself!
