Yamaha YH-WL500

As someone who often has to practice in silence when I saw these headphones which offered a wireless I purchased them straight away.
They are exactly what they say they are. The latency of these headphones is low enough that it can be considered non-existent. The freedom they offer for anyone tired of getting tangled in wires is almost worth it alone.
They sound is a bit more to the bass-y side but can be corrected with EQ.
The cable for the plug is very short though I discovered it works perfectly fine if plugged into a USB port in my desktop so they are easily within reach.
These minor gripes aside they are very comfortable and the semi-open back means they can be played for hours without fatigue.
I currently have they hooked up to my Quad Cortex and even with the Cortex feeding through my DAW and back out and the round-trip latency all that entails (my PC is very fast) it is still well within acceptable limits.
A great purchase for QoL.

The headphones arrived promptly and are easy to set up but the supplied 'power' connection lead is far too short.
The semi closed backs are perfect for playing guitars, e-drums etc and the latency is very low as described. The Bluetooth connection is very reliable in the same room but it does find dead spots around the house which is not a problem as for me the primary use is for music. They are not cheap but I think they are well worth the money. My only concern is what happens when the internal battery gives up! Overall they have surpassed my expectations and I am very pleased with them.
