Unless someone who actually owns both items says different, I would assume they are incompatible with one another. Everything I've read online seems to suggest that they are not compatible even when told otherwise. If a vendor is selling the items as compatible and you purchase them and they aren't, be sure they have a good return policy.
USB headset is the best option audio quality wise. Even cheap ones should be good and I recommend to choose the most comfortable ones. There is also a list based on Skype user ratings here: https://support.skype.com/en/faq/FA34615/what-are-
There are also a few very good speakerphones, but normally the prices of those start from USD125$.
AFAIK the call accept/end buttons work with Skype for Business only. There is a bit messy workaround described here: https://community.skype.com/t5/Hardware-archive/Lo
My first recommendation for Bluetooth speakerphone would be Jabra 510. Philips WeCall is also good, but as it seems to have only a single button for accepting and rejecting the call then I doubt if the workaround linked above will work. Another one worth looking at is Sennheiser SP20.
Note that the wireless connection degrades the audio quality. USB connection is more reliable.
Thanks for the details @shadowsun28 - The speaker volume slider within Skype is currently not working. Instead please adjust the Skype volume by:
Let me know if this works for you
My headset is a Razer Kraken 7.1
Hello and welcome to the Skype Community.
There have been several recent reports concerning this headset model complaining of lack of audio. Try using a different brand to see if the problem is replicated.
I specifically inquired about this recently and was told nothing has changed. Dedicated hardware like the 3088 that doesn't rely on the Skype Desktop software should continue to function as they don't pose the same security concerns that older desktop versions do. If this for some reason changes in the future they would undoubtedly post an official statement on it.
