How much does the integrated amp increase the volume when used with a headset?

It doesn't increase it at all it's as if the headset is directly connected to the phone.

To clarify: as I stated on line 3 of my answer, this is for my personal use during SOLO practice sessions. During an actual match with a live Range Officer, I utilize the built in microphone without any problem. The answer from Keith is a bit inaccurate - the plug-in feature works, however, it severely attenuates the input signal. Increasing the device line output should provide a usable sound level. As a pistol shooter, the size is not an issue.

This headphone has a volume control and allows you to select from no amplification to quite a bit. I don't know the actual dB rise, but it can be more than a hearing aid that's for sure.

Only need a few minutes. The tube is in a buffer stage. So, it doesn't increase the signal gain. Just sets the impedance to the headphones and add a bit of tube "flavor" to the tone. Most of these cheaper headphone preamp-amps are setup this way. Voltage applied is low, as is current through tube. It will never get as hot as tubes used in input and gain stages. HTH!

It's a volume amplifier. Just boosts the volume. Kind of like a "high" and "low" setting.

It reduces the ambient noise, the Sony pair I had it increased the volume and it was evident. There is no volume difference with these when I switch back and forth.

I haven't tried it, but it looks like a mini-plug type extension (like what is used on a stereo headset) would work. The plug type is the same. The extensions are cheap. Would be worth the experiment. Now you've got me curious...

I'd be remiss if I answered your question, as stated. I run my 100a through a graphic equalizer then into two Boston Acoustic VR-12s, a Dayton Audio 100 watt subwoofer amplifier and 12" Pioneer woofer. Tuning the amp's output to my listening environment and taste significantly disguises the inherent audio emphasis of the 100a.

It may depend a little on your device, but it certainly won't be cut in half. I notice little to no reduction in volume when I plug in a second headset, although it varies slightly depending on the device. So far, I've used it on a Sansa Clip+ MP3 player, a 7" Android tablet, and my laptop.

Yes, there's not much difference between what you describe and a normal setup with an amp and an internally connected speaker, so the result would be the same, a boost in signal that is adjustable.

not sure about the amplified db level but the sound is loud and clear. i usually turn the TV volume up and mute it. I can adjust the headphone volume easily with the control on the headset. so far so good. the only complaint i have is that after wearing it for an hour or so, my ears hurt. the company should have a better design in this area. be bold and be innovative.

I guess it depends on how loud the sound is. I don't listen to very loud music. The headset has a nice quality and can easily cancel any external noise. So I don't need to increase the volume to enjoy it. I asked people living with me in the same house. And they say that can't hear anything. But iam not sure about very loud music. Sorry for the super late response

I don't know. I bought it to amplify headphones. It didn't work like I wanted it to. So I threw it away.

It doesn't improve it per say, just makes it louder. If you want improvement, then you need to purchase/upgrade your DAC, cabling and headphones.

No, it doesn't affect output volume, it changes only volume of signal, that you hear in your headphones. That's the point of this device)

I bought it primarily for the amplification, the visual features were an unexpected bonus. I always have the volume turned up loud. If you can wait 2 weeks, I'll try it at low volume and let you know. Otherwise, I would call Plantronics technical support who were very helpful.

I would say no. The comments I've read (on head-fi) say that to get decent output out of high-impedance cans you'll have to use something more powerful. If going the vacuum route, that might be the Schiit Lyr or Asgard 2. I am using my Valhalla with 32 ohm headphones so can't comment on how it sounds with 600 ohm headphones connected.
