Plantronics Discovery 665 Bluetooth Earset - DISCOVERY 665
PLANTRONICS Discovery 665 Bluetooth® Headset

What a great deal this Plantronics headset was!! A USB charger, a wall charger AND a car charger!! WOW!! This isn't my first BT headset, I have had Motorola and Jabra in the past and this is by far the best. Nobody ever even noticed that I was on my headset until I mentioned it! The sound is great...sometimes a little static if my phone gets moved around and the answer button is a little tight but not that big a deal. It paired quickly and easily with my LG Chocolate and it fits perfectly inside my ear. First charge held for roughly 4 days on limited talk time. The little carry case is a plus because I can clip it to my shirt or in the pocket of my purse and find it easily when I need to. I love this headset!

With all the different flashing lights, which all mean something different, this device took a bit of getting used to. But now that I am familiar with the many lights I love this headset. I love the easy carrying case. It protects the unit while in my shirt pocket. No more fumbling around to find this tiny ear piece. The noise cancelling features are fantastic. I hear callers perfectly and they hear me. The sound quality is perfect. The unit is so light I forget that I have it in my ear. There is plenty of talk time and it gives you plenty of warning that the batteries are fading so that you can finish up a call. It was simple to progam and connect to my phone. And it reconnects almost instantly. An excellent buy.

I've owned many different headsets over the years and I find the Plantronics Discovery 665 a solid performer. The sound quality is good, value is great and the many charging options are a plus.

This unit fits the bill for every use except when you need and use it the most...IN THE CAR. It has terrible wind noise on the other parties end. With this in mind, I still believe that the Jawbone is the industry standard.

The sound quality, both on sending and reception is great. Friends don't complain that they can't hear you and you can hear everything they say. Also very comfortable to wear.

I have had charging problems with this unit and have filed for replacement with Plantronics, this week. Have not heard back yet. Other than this problem, the unit works very well and is easy to use once you get use to it. Volume is very good and noise cancelling is fair.

The headset is very light and easy to use. It worked well with the MotoSLVR L2 phone and OK with the MotoKRZR K1 phone. I believe that BT is directional and the phone needs to be within a specific envelope of use. Voice is very clear with the MotoSLVR L2 and is sometime fuzzy with the MotoKRZR K1. I primarily use it in the car. Wind noise is a problem if planning to use it outside.

This is my first bluetooth headset. I paired the headset with my iPhone and use it primarily in my car (2007 Honda Civic). People complain of background noise when I have the A/C blowing on me or when I'm driving with the windows down. Other than that I think it works great. I can hear clearly. I love how light it is. I don't have to use the over the ear attachment because it fits securely in my ear (comes with multiple ear size pieces). I haven't used it for more than a 1/2 hr at a time but no discomfort after using it. I love the car charger and auto-answer when I pull the headset out of the charger. If a call comes in while it's in my ear it also beeps in my ear. I would recommend this headset.

I've owned several generations of Plantronics BT headsets including the Discovery 640 and 645. This is by far the best of the Discovery series, and my everyday headset as a result. Good clarity, volume, excellent carrying/charging pen that can be tucked into a pocket like a regular pen, small size and very comfortable in ear, no need for earloop (though it is an option). This one is much less sensitive to wind noise than past generations, but is not a heavy duty active noise cancelling headset that you can use with windows down in the car. I can even use my old 64x accessories with the 665, and do keep the mini-USB charging adapter from my 645 on the carrying pen so I can charge phone and headset with one charger. The 665 fixes all the key problems with past Discovery headsets: longer battery life, never falls out of the carrying/charging pen, the carrying pen now has a rubber tip on the shirt clip that means it never falls out of my pocket, and the ear jells stay connected to the headset better. Only issues I have are 1) the 665 sometimes looses connection briefly to my Motorola Q, but a double press of the main button generally brings it back, and 2) of course, heavy winds are too much noise for it to handle. I've tried a number of other headsets over the years seeking better wind noise cancellation like like those from Gennum or The Boom (I still keep a wired second gen The BOOM headset around for this purpose), and will be trying nXZEN's nx6000 next. In the mean time, the 665 is my top choice and I use it daily.

I have been using Plantronics 6xx for a while ... 640, 2x645, and just recently upgraded to 665. Considered the Jawbone, but it was just too bulky even though performance was better. For me small form factor and ease of use was priority. As you can imagine, I have all the legacy stuff, which makes it much easier than starting from scratch. so the omissions of the necessary items do not bother me. Car charger though a good idea, is pretty much useless for me. Add of the USB charger was definitely needed ... what I use most on travel. Missing is the battery charger ... the other necessity. Missing also is the Wall charger ... necessary at home. Relative comparison to past products. Bluetooth link very fast... much improved. Pickup out of cradle is near instantaneous ... much improved. Audio quality on far end is better than previous, not total noise canceling like jawbone, but reasonably good. Elimination of vibrate on ring is not good, but my phone vibrates, so not too bad, but wish it were still there. I have a BB 8100 cell phone on T-Mobile. Hope this helps.

This is the 1st bluetooth headset I've ever used, and it is a different experience. Even though I'm tech saavy, I feel like a caveman approaching the monolith from 2001! The documentation was a little sparse, in my opinion. Maybe I'm still learning how to use it properly, but I'm experiencing some quirks: The headset paired to my Motorola Q just fine. But it seems to have a mind of it's own as far as when it's going to pick up the audio and when it's not. If it's powered up and I start to dial on the phone, I hear the tones through the headset. Then, when I press send on the phone, the audio is transferred back to the phone for the first 10-15 seconds of the call. Then, the headset picks up the audio again all by itself. Shouldn't I be able to hear the entire thing through the headset without the interruption? If I have to hold the phone up to my ear for a few seconds, doesn't that defeat the purpose? Sound quality seems... ok. It gets the job done, but it's not going to win any awards. From the reading I did on BT headsets before I bought this one, it seemed obvious that sound quality just isn't the best no matter which one you get. Any background noise or wind is very noticeable. The unit is very lightweight. The different sized silicon earbuds were a nice touch. I was glad to select the one that fit the best. On the first full charge, the battery seemed to run out much quicker than I expected, but since then battery life seems ok. Again, maybe I'm still learning...
