Pros: Great mids and highs.
Cons: Presentation not properly anchored, lacking in midbass! Physically heavy hence not suited for extended listening!
At budget prices there is not much one can expect from headphone manufacturers. These budget headphones have to balance pricing and performance to be competitive but the Lasmex H75 Pros ( rebranded Somic MH463) seem to have found a decent balance. They don’t look overtly “plasticky”, maintaining a reasonably reassuring build. The metal band that runs across both headphone frame is pretty sturdy and the remaining parts are made of tough plastic. A three year guarantee is greatly admirable and definitely helps the buyer to be more confident with the headphone, ofcourse this may depend on the rebranding vendor. The headband also seems to add considerable weight to the headphone, which makes it heavy over extended listening sessions The markings on the metal band help in making quick adjustments and are much appreciated by users like moi! The headphones have an impedance of 45 ohms and have a 50 mm driver. The large driver makes the headphone quite substantial to look at and most definitely also plays a role in the well resolved sound the headphone puts out (more on that later…). The headphone has an open type construction meaning, there is going to be leakage of music to the surrounding, the size and open nature of the H-75 Pro will mean you would ideally be using these indoors. A 3m cable terminating in a 3.5mm stereo plug with a 6.5mm adapter completes the Lasmex H75 Pro.The earpads cushions are unusually too soft and do tend to compress too much. Though that may not affect all, users like me (not small ears!) have comfort issues. The earlobe tends to rest on the hard plastic containing the drivers and causes comfort problems during extended listening periods. Yet another discomfort is the sheer weight of the headphone itself! The plastic lining bearing the branding “Lasmex” covering the headband seems to be the culprit, you can always remove that to increase comfort and probably replace it with a third-party headband cushion.
The H75 Pro weaves magic with vocals! I had been listening to the HiFiman HE500 for a few months ago and then moved on since, I did not have the right amplifier and the H75 pleasantly reminded me of that headphone.Yes, the HE500 is in an altogether different league but the H75 does truly have a good, no Great (for the price!) presentation in the mids. Can’t wait to try it on with a tube amp, unfortunately don’t have one at the moment . The headphone portrayed a very natural and sweet mid frequency presentation that is portrayed in an intimate manner than the bass and high frequencies, when supported by the Burson HA160 & the O2 amp the vocals were very good. Ideally, alternative, pop, vocal Jazz and other mid centric content shine with this headphone.Though when the volume is pushed beyond reasonable levels I did not notice some distortion in the mids. The performance of this headphone rests so much on this part of the sound that it is not as impressive with genres like dance, techno and electronic where not much attention is required in the vocals. A beautifully resolved and airy presentation with the right amount of shine. The treble is definitely one of the strengths of the H75 pro. A very rich but untiring treble as observed in other higher end & expensive headphones. The amount of instrument separation and air in the high frequencies is just unheard of at this price point!
Coming from the HD650 it is quite difficult to get used to a presentation that does not put as much intensity and richness into the low-end. The bass on the H75 Pro is quite linear and neutral with some presence of sub bass as well. It does have enough quality, but definitely seems to lack in midbass quantity for my tastes. This perhaps, has to do something with the presentation style that the headphone adopts. The beautiful mids in the foreground with clean and clear highs seem to demand a suitable amount of low-frequency (midbass) support to really anchor the presentation, unfortunately that’s where the Lasmex H75 pro let me down. One cannot plainly complain about the bass of this headphone, its does make itself felt when called for by the music, but feels slightly anemic.As mentioned before this observation could also be due to the time that I spent with the HE500/HD650 and somehow fixing that presentation as the standard to judge similarly voiced headphones.
The Lasmex H75 Pro or the Somic MH463 is a well executed headphone design with very little drawbacks. The comfort problem is something that would be a pain for some listeners, the lack of a slightly weighty bottom may as well leave some listeners unsatisfied.Tip! The Somic Ef 82 Mt is another offering that seems more appealing than the MH 463 in terms of sound.
