This is the CVJ ARIA. It's an excellent model, highly regarded among recent CVJ products. In addition to the high quality of the main unit, it allows for detailed sound tuning with three types of filters and three types of nozzle replacements. The included cable is also a high-quality one, sold separately as the CVJ Candy. Furthermore, the cable's plug can be swapped between 3.5mm and 4.4mm, allowing you to listen to both unbalanced and balanced connections with a single cable. There are many reviews online, so please refer to them. I own this model myself and purchased an extra one for a friend. However, my friend had already bought one after hearing the good reviews, so I'd like to offer it to someone who needs it. Thank you.
