Model overview based on user reviews  
The Superlux HD669 headphones offer excellent sound quality at an affordable price, making them a great choice for those who know what they need in audio equipment. They feature a durable construction and a practical cable connection solution, including a 3-meter cable. However, the ergonomics could be improved, as the headphones tend to press on the head and become uncomfortable after extended use, especially for those wearing glasses. While they deliver a well-balanced sound and respond well to equalizer adjustments, they may not be suitable for long gaming sessions or everyday use due to the discomfort experienced after about 40 minutes of wear. Overall, they are ideal for short listening sessions and those seeking high-quality audio on a budget.
Pros

Cons

In general, very good headphones, for people who know exactly what they need.

The sound is amazing for the price. For its full disclosure, a separate audio interface or a high-quality player is very desirable, although they are good friends with ordinary audio chips in a PC

For some, the ergonomics were especially disappointing with the two top pads, they do not fit very comfortably on my head and get crushed over time. Also, glasses are uncomfortable.

The sound is decent, pleasant to listen to, quite well balanced, you can find their frequency response (FR) on the internet and check it out. They respond to the slightest changes in the player's equalizer. As this is a full-sized option, they are quite large and completely cover the ears. However, they press on the head quite strongly, and after just 40 minutes of use, you just have to take them off. This is especially noticeable for those who wear glasses, as the frames are also pressed due to the headphones. Unfortunately, I can't recommend them for gamers or as everyday headphones.
