I have been looking at the YH-77STA headset for CW use when portable. I already have a nice headset but want something lighter and without the mic. Has anyone had experience with this model? It sells for $85 at HRO and I don't want another $20 set of headphones for $85. How would it interface with a FT-450D or FT-991A? Since it's Yaesu I would think well enough. I don't want to resort to an 8 ohm set due to mismatch. Any experience...or other recommendations welcomed. No Heil please...I already have their headset...good but their earphones are overpriced. Thanks.
