Can this be plugged into a landline phone?

No. The Sennheiser PC 31 has separate microphone and headphone plugs. It is meant for use with a PC. If your landline phone has a headset jack on it, it is probably a 2.5mm jack for a headset like this one: http://www.amazon.com/Panasonic-KX-TCA60-Hands-Free-Headband-Cordless/dp/B00007M1TZ

As far as I know, it can't be plugged directly into a landline phone. If the phone signal is being fed into an audio amplifier that has a microphone & headset JACKS, then you can plug the unit in those jacks. I use it with my desktop PC, equipped with a mike & headset ports. Try contacting Sennheiser Technical Support for advice.

Hi! You can hook up the BASE of this phone to a regular land line (with normal telephone jack), and then the VOIP841 handset can be used to make normal landline calls. You can switch between land line and Skype Internet calling.If you are asking if you can use another cordless phone with this product instead of the supplied cordless phone, the answer is NO.If you are already subscribing to caller ID on your landline service, then YES this phone will show you the caller ID. But not if you are not subscribing to caller ID.

You can use a cell phone adapter with your cell phone. So, you don't have to have a landline.

I would need a sketch of your landline. The audio input & output of your landline would have to have RCA jacks also the volume of a persons voice speaking to the input would have to be low & controlled; no loud outburst otherwise you'll blow the volume control; This is just not human nature & sooner or later you'll slip. That's why the input to the volume control must never come from an amplifier!

If I am understanding your question you want to know if you can connect with a old landline. Yes, it works with just an ordinary phone line. The additional phone only needs an outlet and no phone line to work. It receives it's information from the main phone base. If you however mean that you have no landline and want to know if you can use them without phone service the answer is no, you must have service.

I think it can. Instead of plugging the telephone line directly in to your phone, you connect first to this and from this to your telephone. So I don't see why it wouldn't work.

This device only works with a corded phone. It connects to a phone base at one end and handset at the other. If you don't have a traditional landline phone with your TV/Internet/Phone Cable Service, you won't be able to use the device.

Yes it works just fine with a hard wired landline, I have it connected to my office phone.

Yes. The HOME button is used for a normal landline. Standard telephone cord is included.

This is 3.5 mm headphone jack. If you are going to use it with landline phone, maker sure your phone has 3.5mm headphone jack input.

I believe you can get a cell adaptor so you can use cellphone. Without that, I think its land line only.

I don't know, I have a landline. If you find out though let me know since I also have a cell phone

It should though I haven't used it on such. I've used similar ones on landline phones. Basically if it has a jack for it, it'll work.This is assuming you are trying to plug it into the hand set and not the wall. It won't plug into the wall.

Hi, I don't think it will work on a standard land line phone jack because the plug is round.

Thats correct. You can not use the device with a landline to make an outgoing call.

Not to my Knowledge. It is made for land lines. It would work, but you would need an adapter for it.

I have not had any direct experience but I would assume it is similar to pairing with a bluetooth mobile phone. I would read your owner manual for the landline phone to see what it says about pairing with a bluetooth device. Between the two instructions (phone and speaker), you should be able to get them together.
