weishan ath m50x 3.5mm to 2.5mm Adapter Compatible with Audio-Technica ATH-M40X ATH-M50X ATH-M60X ATH-M70X, Sennheiser HD598 HD518 HD558 HD595 HD595 HD598se HD569 HD579 HD599 Headphone Jack Adapter

It works perfectly with my headphones.

Tiene una excelente calidad de audio. Cero Pérdidas. Me funciona de maravilla al conectarlo a unos audífonos Bose. Muy satisfecho con la compra. Excelente relación Precio-Calidad.

Works with my Sennheiser 560s. I use it to connect a boom mic. Works great. It adds a little length to the connector but that doesn’t cause any issues for me.

So far it works good, no sound degradation, decent build quality, only complaint is its a little longer than I'd like, on occasion when tilting my head to the left the cable will poke my neck.

I purchased this so that I could use a standard 3.5mm aux cord with my Sennheiser GAME ONE headset, as as this point it doesn't seem possible to purchase genuine 2.5mm replacement cables from Sennheiser. This adapter will work in the headset, but it does require shaving down the notches on the red part of the adapter. I find no difference in sound quality using this adapter with the headset, though the connection is a bit loose.
