I've had these earphones for a couple days, and here's my take on them. The Oneplus Buds Pro 3 are the most expensive buds here, and they are like my other high-end buds. Everything is good, though I think that the transparency and ANC is a little lacking compared to the likes of the Jabras and Samsung buds. These buds are a tad bass heavy, but it was still kind of balanced in terms of sound. The cheaper buds, the Oneplus Nord Buds 3 Pro, are the cheapest earbuds I own, and they are pretty generic. ANC and transparency is noticeably worse than the higher-end buds, and the sound is a bit lacking (especially the mid-range vocals. Watching YouTube videos, you can here a noticeable change in human voices, but it may be just me). But, I only paid $30 for buds that are worth $80, so I would still say it's a steal. Lastly, the 7Hz IEMs are the very first IEMs I've ever owned, and I was blown away by the clarity in the sound. The sound quality, for only $25, is really shocking. IEMs really take music listening to the next level. I could here all the different parts of the song, especially instruments in the treble area, very distinctly and clearly. Bass was good as well, but these IEMs brought a totally new element to the treble than wireless earbuds. Overall, I am most happy with my Zero 2s, even though they are the cheapest out of this Christmas haul.
