Periodic Audio - 3 Models The only difference between the three models is the material of the driver diaphragm. These are very unique products. You can enjoy the differences in their individual characteristics. I want you to compare the three types by listening to them, so I'm selling them together. ❌ Be (Beryllium) 18,000 yen - Sold Ti (Titanium) 16,000 yen Mg (Magnesium) 12,100 yen Total: 28,100 yen I have only used these at home, so I think they are in relatively good condition. Only the Be model comes with a box. Everything in the photos is included. Operation confirmed, playing without any left/right balance issues. Referencing personal reviews: Be (Beryllium): The best. Amazing. Ti (Titanium): Flat. Good for distinguishing instruments. Mg (Magnesium): Dynamic sound. Best for pop and rock. I liked this one the best at first. Great price!
