Sennheiser Enterprise Solution 615104053601 CC 540 VOIP Telephone Headset

After reading the product description I was under the impression that this headset was compatible with most telephones and call center devices as it came in the box. Not so. You need to obtain an adapter for your specific telephone. No where in the description does it tell you that.Until I find this adapter I am unable to use this headset and be in posiition to evaluate its performance.

I really like these when they work. To make them work with USB you must purchase an extra adapter and the connector between the headset cord and the adapter cord doesn't work well and makes causes static sometime. If you connect and disconnect repeatedly, then the contacts will clean and it will work for awhile. the second larger problem is that the cord on the headset breaks over time and it can't be replaced. You have to send it to Sennheiser and a swap out that costs $85.

I've been using this for about six weeks. It replaced a cheap $20 unit that had one earpiece and a boom mike that had inadequate pickup.First, the earpieces. I'd heard that some folks had complaints about these things being delicate and difficult to replace. It came with two extras. The sound quality in the earpieces is phenomenal. It is LOUD! I have to turn down the volume on my phone all the way usually. In the occasional situations where someone calls me with a really weak voice, I can turn up the sound and no problem. So the sound that the earpieces produce is nothing short of outstanding.Second, the boom mike. I tested it with several folks who said good things about the sound quality. It seems best with the mike about two inches from my mouth.Third, the headset comfort. My only complaint about the performance of this thing is that the padding on the headset (i.e., where the frame touches your head) is inadequately padded. It could use some more padding. It would be nice if it were padded all across the top of the frame, instead of being padding-free in the middle. So its comfort suffers somewhat because of this. If I wore it all the time, this would be a bigger deal. Fortunately, I only put it on when talking on the phone, so this is less of an issue for me.Note that you MUST buy a separate piece in order for this to work for you! This unit will NOT plug into your phone. You need to buy an adapter that plugs into your phone. Exactly which one is appropriate for you depends on the phone. For me, I needed a CCEL-191 headset cable ($22.18), which works fine.Overall, while this thing is really pretty pricey, I'm quite happy with it.

Been happy with this headset. The foam earcushions were a bit tight and brittle, so, as a public service for others buying this product, be patient and careful slipping them on. I have contacted Sennheiser and other suppliers: Nobody seems to know where I could get a replacement pair. Other than that, the headset works great and has improved my presence on my teleconferences.

Like the other customer, I too am unable to use this product as it doesn't include the adapter and I had no idea I needed one. I have an important project due in 2 days and am disappointed that, after having this producted overnighted, I am unable to use it. This information needs to be added to the product description. I'm sure this is a very good product. I'm just unable to tell.

This is the first headset I've been completely happy with. Previously, I struggled with ear pads that were small and uncomfortably hard along with microphones that could not be adjusted properly.I no longer struggle.This headset is completely comfortable, and the microphone produces clear, intelligible speech. I use it with Dragon Naturally Speaking and couldn't be more pleased with the results.If you need a good headset, by all means, give this one a try!Phyllis Staff, Ph.D.author, "How to Find Great Senior Housing"and"128 Ways to Prevent Alzheimer's and Other Dementias"
