Question: my IP phone has a 'Headset jack / sub-mini-phone 2.5 mm.' will this fit?
Document: I bought these to work from home on the phone. They have held up after daily use. Very light weight and no problems with clarity or static. They do have the 2 plugs which will work with most voip or call center systems so you will need a USB adapter($2-$5). In fact I purchase the Logitech clearchat and returned them and went back to this set. Buy with confidence.
These are light, fit well, and sound fine. THey sound better than I'd expect for the price. No, they're not audiophile headphones! But they sound fine for casual listening, a bit light on bass. They also work great for phone headsets, which is my primary purpose.Unfortunately, the telephone adaptor cable recommended by amazon doesn't quite work: unless I hold the headphone plug tight in the adaptor cable's jack, I get audio on right side only. I consider this a flaw in the 3.5mm jack in the adaptor cable, since the same 3.5mm plug works fine in my laptop.I expect these will be comfortable for long phone conferences.I have a relatively small head with high ears, and a lot of headphones won't go small enough for me.
I received it with great anticipation, and after playing with the adjustments a bit (found that earphone volume all the way up, but microphone volume at "medium" allows me AND the listener to have optimal reception), I can now talk on the phone and walk or run on the treadmill without any problems. It was worth the search - especially for the price. But DON'T FORGET everyone (if you plan to use these for your telephone) to get the "Headset Buddy Adapter: PC Headset to Phone Adapter PC35-PH25" - which converts the *dual* 3.5mm male ends of these headphones to a *single* 2.5mm male end (to fit into your phone's single female connector).
I bought these toi use with Magic Jack. They fit real good and have good Mic pick-up. They won't work for stereo listen but for everything COMMS.Thanks
I use this for calls with magic jack and it has worked well. The headset seems to be pretty comfortable & sound quality is good for phone calls.
It's comfortable, decently priced, decently durable, easy to use, and all and all a pretty standard headset.However, I ranked this headset a 2/5 because I'm currently in the process of buying another. You get what you pay for and it's decent in that regard, but my online friends have complained that the poor voice quality makes it hard to understand what I'm saying at times.It's important to me that the people who I speak to understand me clearly, so I will be buying another, higher quality, headset with better voice transmission.
Good product. Am not happy with the markings on the 3.5 mm pins that identify earphones and microphone. Can hardly see it. Must be color coded with today's conventions - red/pink for mic and green for earphones. However, the product works fine.
No problem with these. I suspect they'd even fit most kids over 10 or 12 yrs old. They extend long enough to rest on my chin, so I suspect they'd fit a large head well too.I downgraded from 5 stars to 3 because the connector was flaky and I had to resolder it. After that, no issues. But darn, those tiny cables are hard to solder!
I have a fairly large head (wear a size 7 5/8 fitted baseball cap) and these fit perfectly even for me wearing them extended periods of time I noticed very little strain on my ears or the top of my head once I got them adjusted to where I needed them. The headset is clear and the microphone works as good if not better than I had anticipated. The inline controls worked well and the overall assembly seems pretty tight and not too flimsy.Cons:Everything is plastic and even though it should be sturdy enough to handle anything I have my doubts about that.
I love using my headset when I have meetings over the phone, or whenever I have a phone call over 2 minutes.My fiance had to buy an adapter for me to use this with my Samsung Galaxy S2.
Answer: This set is for computer use which means you have to plug one into the headphone jack and one in to the mic jack. Will not work with a mobile phone without an adaptor that pairs both signals into one. You can purchase those here on http://amazon.com, however, I found that it didn't work very well on my phone but was fantastic on the computer. Hope this helps. Look specifically for a Mobile phone headset. Have a great day and best wishes!
