An Amazon-approved vendor has carefully inspected and tested this previously used item. No apparent defects will appear when held at arm's length. This product's battery capacity will be more than 80 percent more than that of a new model. Even if the accessories aren't original, they'll still work perfectly. A generic box may be used to ship the merchandise. Sound quality for what it is is fairly good. Because it's so much easier for me to hear and for others to hear what I'm saying, I actually use this in my car instead of the Bluetooth. When you're working out, you'll definitely hear it.
WindSmart is the only company that use the technology. In order to make sure your voice is heard clearly even while you're outside, we developed six levels of unique WindSmart technology. Comfortable design that has been tested and proven: Your final call of the day will feel just as nice as the first since it has been thoroughly tested for stability and comfort on a range of ear shapes. Time Allotment & Mobility: Talk duration of up to seven hours. Freedom of movement up to 98 feet in length (30 meters) As long as your laptop has built-in Bluetooth and your adapter supports the required profiles (HSP for calls and A2DP for media streaming), you may connect any of the supported Bluetooth headsets and utilise them (including our Voyager 5200). The BT600 adapter is not included with the normal Voyager 5200, which is what you see here. In addition to the BT600 and the charging case, the Voyager 5200 UC model comes with component number 206110-01.
The earpiece and charger in question should not be purchased. This noise cancelling stereo headset has a dynamic EQ with wideband audio and an enhanced DSP for intuitive in-line call answering and ending controls. Amazon-approved sellers have properly inspected, tested, and cleaned this previously used item. There won't be any noticeable visual faults when seen from a distance. This product's battery capacity will be more than 80 percent more than that of a new model. The cable for the Legend is provided, not the one for the 5200. Poly (plantronics) doesn't provide an economical, simple magnetic charger for the 5200, and the base has been redesigned to the point that it no longer fits the voyager charger. Because of this, they'll happily overpay you for a large, unwieldy case/docking unit. Even though this product has been in my possession for more than a decade and is unquestionably the best on the market, I do have seven charging ports that are no longer functional!
