Отзыв о Хотитех проводная гарнитура для телефона моно с шумоподавляющим микрофоном, совместимая с ShoreTel, Plantronics, Polycom, Zultys, Toshiba NEC Aspire Dterm, Nortel Norstar Meridian, Packet8 и настольными телефонами Landline Deskphones (F600S2) от Justin Peck

I had to replace my headset on my Polycom VVX500 at my home office (my dog actually ate my old one). I was pleasantly surprised that the headset worked immediately with my phone with no adapter and without changing anything else. I could not assess the claims for noise cancellation. I called from the headset and left myself a message and the sound quality was not crystal clear but was acceptable.This is not an elegant headset like some others but it looks nice enough. More importantly, it works and was a good price. As you may guess, this is made in China (ugh).The headset came with 3 different adapters in case one was needed. My headset worked with the VVX500 straight out of the box though.
