You run with the Bose QC35 and Philips Fidelio X1? I can't picture that working well at all. Like most people, I prefer to use around-the-ear or open-back headphones at home - at my desk or walking around.
Yes, the QC35 and X1 are well-built headphones... but cost $250 and $350, respectively. At $80, I would bet that the Lasmex L-85 is among the best-built, lower-cost, currently-being-sold headphones in the world.
Yes, the light-weight QC35 is more comfortable than the X1 or Lasmex w/ stock earpads. But I perceive no issues with the Lasmex headpad. Unlike the the X1, the Lasmex doesn't have elastic that can stretch-out (and eventually snap) over time due to normal usage.
Why is the L-85's price a mark against them? Lasmex is not a well-known brand, so they were wise to charge less than a similar-class, name-brand headphone. If their stock V-shaped sound was replaced with my customized EQ profile, I believe that Lasmex could justifiably charge $300 or more. I find it curious that a headphone as good-looking and well-made as this can have such a unappealing, unnatural frequency response.
True, "good" sound is subjective, but replicating real sound (with quality microphones, headphones, speakers, amplifiers, cables, etc.) should be the goal - at least for audiophiles. Simple graphic EQ makes these headphones sound "good" to me.
In headphones, I look for sound realism and value (price-to-performance ratio). The QC35 and X1 are excellent headphones for their intended purposes, but neither come close to sounding real. EQ could possibly help them. But I doubt it, considering that the QC35 has a closed-back design and is made for wireless/noise-cancelling. And the X1 has a gimmicky, ultra-wide sound-stage and grainy sound.
Yes, the Lasmex L-85 is a "mediocre" pair of headphones. But EQ-ing them "to hell" (with free software) transforms them into excellent headphones for home use. And I don't feel that their bass performance is lacking at all.
One final thing to consider is the DAC/amp being used. I'm current using the relatively low-end Micca Origen+. Once I upgrade, I'll report any improvements I hear with my L-85's.
