FlyingsCool Posted April 21, 2017 Share Posted April 21, 2017 So, I've been whining for quite a while about how my Shure SRH840 44ohm headphones sound like poop with when connected directly to Helix. As a matter of fact, they were so bad I hadn't tried them in a long time and they actually sound better now than I remember them.... Not sure if that's a function of the upgrades since I last tried to use them. But stuff like fuzz pedals still blow them out, make the tone seem to actually have dropouts. I did pick up a pair of Beyerdynamics HD770 Pro 250 ohm cans. While they seem, boxier maybe, certainly less detailed in the mids than the 840's, they do react better when connected directly to the Helix and are sort of usable for tone shaping kind of. Anyway, I was perusing THE THREAD for impedance and came across this... perhaps I had missed it in the past, or it didn't sink in, but... be that as it may, Digital Igloo and Line 6 addressed this concept a long, long time ago... So here you go for all people wondering about using headphones with Helix... a quote from the incomparable Digital Igloo Bass in Zurich said: â†‘ Also interesting is that my flat response Audio Technica headphones (these) sound really, really, bad. The budget Sony (these) headphones sound a whole heap better. Those ATs are 38 Î©? That could explain it. Low impedance headphones are designed to provide ample volume when listening to devices with relatively wimpy headphone amps, like mobile phones and iPods. Another user elsewhere expressed concern with his Beyer DT990s (which come in three variantsâ€”32 Î©, 250 Î©, and 600 Î©) and I'm willing to bet his are 32 Î©.I'm actually surprised your Sonys sound any better, as they're even lower, at 24 Î©.Helix's headphone amp is LOUD; it's designed to drive high-impedance studio headphones to stage volumes. Low impedance headphones distort way faster, fatigue your ears, and at a high enough volume, can damage your hearing. With Helix you could conceivably split the headphone output to two pairs of 200-300 Î© cans/IEMs and drive both over the sound of a drummer (and adjust respective levels via MIDI CC control of path output blocks). My band does this now.Personally, I use Sennheiser HD600s (300 Î©), and before those, the HD580s (same). Also have a bunch of Sony 7506s around, but they're 63 Î© and harsh-sounding already, even with an iPod. I also keep a pair of Sennheiser HD280 Pros (64 Î©) at work and they're pretty boxy sounding, but if I can get a mix to sound good on them, it'll sound good anywhere. I treat them like wearable Yamaha NS10s, if those NS10s were powered by an Alesis RA100 instead of a Bryston. Wouldn't want to construct tones with them. 1 Quote Link to comment Share on other sites More sharing options...
