Symphonium Audio Helios In-Ear Headphones

Love them a lot definitely my endgame iem

Symphonium makes some really good IEMS. The bass hits like a truck, better than most dynamic drivers. I can hear clarity in the drums and deep sub-bass rumbles. The upper midrange is slightly calm and recessed, lending itself to an open sound. The treble is GOD TIER, extremely smooth, and well extended. The treble never becomes harsh or sharp, when listening to vocals I can hear textures in the voices which other iems simply cannot pick up. The sound signature on this is Neutral with bass boost. If you want a reference sound with a relaxed upper midrange this is ENDGAME for most people. I listened to many iems in this price range and this takes the cake. Conclusion- the helios gets my highest recommendation 5/5 🔥🔥. Pros: Market-leading treble, highest quality bass, smooth midrange, smooth tonality, high quality shells, well engineered Cons: technical performance isn't the best, fit might be a problem

Shipping and customer service was incredible. I would recommend. My opinion about the Helios is similar to every review I’ve seen. It’s extremely good. I find it to be a more balanced version of the Meteor. More details in the mids with the same bass tonality on a flatter curve. Switching between the two the Helios has more to offer but what the Meteor offers is fantastic. I find I like to EQ the Meteor where the Helios is great with none. The Helios does require more power than the Meteor. Topping G5 portable with a balanced cable can drive it but maxed out. The meteor is much easier to drive on the same portable Dac/amp. On a home amp the Helios does it all well. On a portable might not be as loud. I will say they definitely have opened up since listening a few hours. The Meteor were similar getting better after a day of listening. Steely Dan Aja Black Cow on both sounds like a new recording. I never thought of it as having any substantial bass but on these it slams and hits low with power. It’s life changing it’s so unreal. Great all around headphone with no weakness.
