Review on Boost Your Communication: Plantronics S11 Telephone Headset System - Enhanced Audio, Black by Mark Kolipano

Until I started assembly, everything seems fine. I've tried working with him but it sucks. I read that it works better with an office phone, so I bought an office phone. terrible. The last phone I bought was a $70 phone. Terrible. I tested a total of 4 phones and a headset adapter before realizing this product sucks. Replaced by s12. no problems so far. Then I got some crap from the sales lady who said I refused to comply after telling them what I had already done. I contacted the manufacturer again and got a case number but still nothing. So today I'm sending the item back with Revain so they get my money back. Don't buy this if you don't want to be stuck with it. I thought I was doing them a favor by trying to work with the product. If you're okay with squeaking, mooing, not being heard and wasting money. take action. Then I give 5 stars.
