Sennheiser 504552 SC630 USB ml Premium Monaural Headset

Really good sound quality however i found that quite a lot of sound leakage so if you have the volume too high then everyone around can hear.

Ordered these headsets for my office staff of 8 people, and got great feedback all around! It's so helpful to be hands-free, and everyone is able to pick up on calls much faster. We love these.

After two months of daily use, I am confident this is a great product on all fronts. I use it with my Polycom IP650 desk phone in the office (6 lines, high def sound), just needed to buy the "Sennheiser CSTD01 Cable Adapter" to connect to the Polycom. Also use it with my iPhone 6 when I travel, just needed to buy the "Sennheiser Audio Cable" to connect to the iPhone 6. Thank you Sennheiser!

I used a Blue Parrot headset for my car but you get listening fatigue with the speaker. That means the speaker is not quality. I also thought getting away from bluetooth radiation might be a good idea. This SC 630 required more power than my Samsung Galaxy Note II could provide. Using a Y 3.5 mm jack splitter from my phone I connected my phone's speaker output to my Aux audio jack in my car stereo. I connected the mic output directly to the Sc 630.. I took the speaker outputs from the car stereo and adapted it for the SC 630 via a Robinette Box into which the Sc 630 is connected for speaker output. You cannot attach speaker level outputs directly to a headset! The Aux input volume on my Car stereo could be adjusted so I could go from music to a phone call with ... MoreI used a Blue Parrot headset for my car but you get listening fatigue with the speaker.

You cannot attach speaker level outputs directly to a headset! The Aux input volume on my Car stereo could be adjusted so I could go from music to a phone call with similar volume levels. I never get listening fatigue with this SC 630 and can recommend it. I use the S Voice app on my Samsung so I don't end up taking my eyes off the road. The only thing I need to do is have the phone visible and handy so I can take it out of sleep mode and then voice control (S Voice app which is already open) does the rest. You will need the proper adapter to the phone which you can find on Home Essentials Direct. Pros for this application: Great sound, no bluetooth radiation. Cons: Lots of wires and complex to wire if you are not good at that sort of thing. If your smart phone will power this you have it made. Another reviewer says the iphone 6 will power it. I hope its loud enough. I have more than enough volume with my complex method.

This may be a great headset but it just isn't loud enough connected to my iPhone 6S Plus. I use it conjunction with this Sennheiser audio adapter for smartphone: https://www.Home Essentials Direct.com/gp/product/B00OHVUOHM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 It's a great sized headset so hoping someone can point me in the right direction. Maybe I need a different cable?
