Helix vs S-Gear to Headphones is huge difference in Helix Posted April 17, 2017 EVERY time you change the way you're listening, you can expect a change in tone... sometimes a drastic change. Headphones will never sound the same as an amp, or even another FRFR speaker solution. For one thing, they're right on top of your ears...there's no room acoustics to contribute to what you're hearing. But even if that weren't the case, no two amps, FRFR speakers, or even 2 different pairs is headphones will ever sound exactly the same. Just the way it is. The fact that you are happy with the tone through the Friedman indicates that there's nothing wrong with the gear, only that you'll habe you EQ things differently for each output method. It's the nature of the beast. I understand very well but this is far more than just a different speaker or EQ issue. I'm almost believing there is a potential problem with output to headphones via the headphone jack. I purchased the Helix just under a month ago and so I'm new to the forum but I've been playing 25 years, almost all of it live. The Helix isn't my first digital modeler either, but I've been away from Line6 since the XT Live because it just wasn't quite there.
