NO, they are designed differently
PLUSH ear cushion ONLY FIT on PLUSH headsets
The new Plush ear pads do NOT fit on the current Leitner wireless headsets and they will also NOT fit on any other Leitner corded headsets. The Plastic ring they wrap around is different from the Leitner wireless and non Plush LH240/45 models.
Regular Leitner ear pads (cat #2344) will fit the small plastic ring the PLUSH headsets come with.
The regular Leitner small ear ring will NOT fit the PLUSH since the hooks are horizontal on the PLUSH and vertical on the Leitner wireless and non Plush Leitner corded models.
Note: One COULD snap the plush earpad into a swivel version of the LH270/275/370/375, it will just be more difficult to charge while the earpad is installed. If you are gentle/careful, it can work. Make sure that you are seeing the fourth programming light on the right side to confirm it is charging.
The circumference of the swivel ring is slightly smaller than the Plush earpad ring. If you want to order this for a Customer who currently has a swivel version of Leitner wireless, put in a miscellaneous order: "Plush Ear Cushion with Ring". This will NOT work with a pre-swivel headset.
