Are the best wireless headphones on the market. Some of them were sold for $129 dollars. Other than that you really can't get any better than the Sony ones.
(skullcandy bought out Astro anyway)
The A50s are supposedly sub par to the quality you get from the headphones I linked from someone who has the PLYR1 reviews and a set of A50s that they own. Some reviews say that the PLYR1 broke on them but... not sure how or where. Very few bad reviews.
However before 2 years ago it was completely understandable that someone would spend $200-300 on headphones. Do you know why? Because in my personal experience all the $100-$200 dollar headphones broke way too easily and I baby the damn things.
If $300 dollars means 5-7 years of use in stead of 5-7 months it was completely reasonable. However now I have the Sony Pulse headset. The old model

Never a problem. The battery dying out or the dongle breaking is the only issue. These things are only worth buying now at $75 dollar price range (because the Golds are taking that price point) and the Pulse Elite have some physical issues that my or may not exist... However they were being sold for $120 on amazon.
So basically these Gold headphones are the Gold Standard as long as they are structurally efficient.
