This was my first attempt at purchasing a "decent" set of headphones, roughly a year ago, at the same time as I purchased an ASUS G751JY gaming laptop because my main PC was down. I purchased these on the Sennheiser name alone, I regrettably did NOT do my due diligence in searching for reviews, or even delving deeper into the specs......they were an impulse purchase at a "sale" price. I don't recall now, but I believe they were around $100 US on Amazon.
What I WANT from a headphone is excellent musical performance, but with also the capability to game with a mic. I believe I have found that "sweet spot", but not with this headset...that will be another review.
My first mistake was not researching the specs. These are 150 Ohm headsets, which is ENTIRELY too much resistance to be adequately powered via standard PC 3.5mm jacks...or at least, while also having the sound signature of this headset. I found I needed to nearly max the volume on my laptop to even approach a satisfying listening volume.
Strangely, the highs and mids sound quite veiled to my ears, and the bass could be best described as woefully inadequate. I found that pressing in on the bottom of the ear cups with my fingers improved the bass a bit, but then of course you can't game or use your computer at all.
In stark contrast, the soundstage is startlingly wide! I'm not sure how they accomplished this, but I'm still learning a LOT about headphones.
I hated these headphones so much, that in the past year, they've had about 10 hours of use on them total....I just refuse to wear them.
I see there's a PC350 modding thread, and I'll have to give that a read and see if the mods work on the 350SE as well! I have no compunction drilling holes into these, because frankly, as they stand right now, if I destroyed them it wouldn't be a big loss.
I now have a couple DAC/Amps, and even proper power applied can't save them to my ears. I simply have much better options available now to bother with the PC 350SE.
