I bought the HifiMan Sundara in 2020. It took a few hours of "warm-up time" to realise the full potential of this headphone. Besides, it also needs a high-quality headphone amplifier. The short cable is probably due to the audio quality. But I haven't had any problems of any kind so far. You can hardly get such audio quality at a lower price. Clearly my favourite

2018 or 2019. I have since had to install a replacement cable that I bought from aliexpress.
