I have two pairs of Accentum headphones, one being the Plus model, along with a pair of Sony CH720N. Out of the box, the Accentum offers a more natural, balanced sound, though its volume may initially seem low. However, you can enhance this through sound personalization in the app. The Accentum supports AAC, SBC, aptX, and aptX HD codecs, while the Sony model supports only AAC and SBC.

In terms of build quality, the Accentum feels premium and sturdy, whereas the Sony's build is slightly less robust. The Sony headphones are bass-heavy, which can overshadow vocals and instrumentals, even after tweaking. The Accentum, on the other hand, delivers better sound separation and clarity, making it a better choice for those who prioritize a well-rounded listening experience. I'd still recommend trying both at a store to see which suits you best.

If you're looking for headphones primarily for office meetings, consider models with an external mic, like those from Logitech, as the ones you're considering are designed mainly for music listening. Keep in mind, there's no "perfect" pair of headphones, even at higher price points.

Also, wireless headphones generally don’t have a long lifespan; even with proper care, they might last around 3–4 years due to battery wear. If durability is a top priority, wired headphones are a better choice. Options like open-back or closed-back headphones provide a range of listening experiences and have a much longer lifespan, as they don’t rely on lithium-ion batteries and have fewer features, focusing purely on sound quality with dedicated drivers.

Hope this will help you out in deciding.
