I'm been leaning towards the kind that have a connecting cable and Mic on the wire for hopefully better voice call pickup. If there is one thing I know from recording is mic placement is everything!
I went hard down this path recently, and I don't love any of the wireless options....I have on hand:
- Bose SoundSport Wireless Headphones: Gave them to my wife, who has yet to adopt them. They are the heaviest of the bunch, and they just didn't fit well. Sound decent. I didn't get around to mic tests on calls, but I have heard others in my office use them, and on the receiving the mic sounds good.
- BeatsX Earphones: Not too comfy to wear, not great for music. Mic works well, and again, someone else in my office uses them, so I've heard the receiving end. Bonus that they charge with a lightening adapter if you are an iPhone user, but you aren't.
- Shure SE215-K-BT1 Wireless Bluetooth: These are my favorite for music and comfort. I don't have enough hours on them to determine if the mic is going to work out. If it does, I can always move up the line and change the cable to better Shure IEMs.
None are as good for conf calls as my low end Bose wired IEMs that I was using before losing the audio jack on my iPhone. In fact, I'm thinking it's better to just get an office headset from Jabra/Plantronics...
If you can get away with a speakerphone, my office uses these: "Jabra Speak 510 Wireless Bluetooth Speaker for Softphone and Mobile Phone". I was so impressed that I bought a used one on eBay for home.
I'm using a FiiO A3 Portable Headphone and FiiO BTR3 HiFi Bluetooth Receiver for my office listening with large cans that don't require me to be on the mic. None of the receivers I found also transmit BT for calls, making it a hassle to covert a nice pair of cans to a conf headset.
