Review on 🎧 Enhance Comfort and Convenience with Plantronics 84604-01 Fit Kit Earloops Earbuds for CS540 W440 W740 by Mary Hovatter

I have a Savi 700 series headset and after a lot of searching found out that this is an accessory for my Plantronics headset. Although I only needed one of the spare parts, you get the whole "collection". If you're collaborating with other people using the same headset, it's possible that other people in your office are using a different device. Make sure these fit your headset before ordering. Many Plantronics "buds" look the same but are "headset specific".
