Something about me before the review:
I started live mixing as of April 2017 every Sundays. Still quite the amateur but I am quite learning about live mixing
I am formerly a bassist.
I prefer fun-neutral sound signature. A some sort of V-shaped or M-Shaped Frequency response to help me hear the low-end and the high frequencies. I am quite the detailhead, but I would love at least little amounts of soundstage and imaging to at least have some panning details to be clear.
Build Quality
These headphones are like Toy-Grade build like this is like meant for kids handling as far as the feel in the hand. This could quite survive in the hands of the klutzy kids. They feel like premium Auldey Toys in the hand. I have Nothing to complain about the build so much that these Superlux Headphones could quite rival the build of Sony and Audio Technica headphones. The pad replacement is easy, just a twist and pull will remove the pads, so at least they are moddable. The 3.5mm Male jack on the headphones may be something that people hate, but at least for me this system is way better than the Audio Technica and Shure's Locking 2.5mm to 3.5mm because Headphone extension cable is easier to find at least.
Comfort
These headphones are light on the head, but they quite clamp hard. You need to box-stretch these cans before using these. Pads are quite stiff, so you may need replacement of pads if the comfort really grits you
Sound In-Depth Review
Before burn in:
I was just testing this out on a local store(and bought it the same day) using the phone. I was quite interested at my first impressions because they are quite detailed and they have soundstage and imaging that is decent for a closed set of cans. Quite comfortable to listen still, not the most sibilant stuff.
When I brought it home and plugged it into my FiiO K1 DAC/Amp, they showed their true unburned nature. They are Treble Cannons, with the recessive midrange and recessed bass. So, as a tip, DON'T USE THEM EARLY WITHOUT BURNING IN
After Burn in:
I burned the Headphone Drivers 8 Hours at first. Noticed the treble recession like it is Night and Day.
Quite Sibilant still, but still quite unlistenable to some Tracks like Ai Shinozaki's Waruineko(Where the headphone shows the unforgiving sibilance of her shrill voice). I let them burn in for another 8 Hours and they become the perfect neutral cans. I will review them as of how they are now after the 16 hour burn in.
Bass:
The bass is good. Not the fastest but at least the details of bass tones are heard clearly. Mid bass can be clearly heard but it can be quite a struggle at some levels especially when there are electric guitar leads that also come with the song. It can rumble once it gets to the sub bass, but sometimes it is quite teasing to the ears especially on EDMs. One thing is for sure. The HD661 has a clean bass, no Muddiness at all.
Mids:
Mids are slightly recessed after the burn in. but they are decently audible for the details to come up and quite accurate enough for my monitoring tasks
Treble:
This is one of the main reason you will either buy or avoid buying this unit(unless you are into modding). They are quite strident. This headphone is unforgiving to shrill female vocals. The Crash will Crash unto your ears. The sibilant sounds will surely pierce your ear drums. The Electric Guitar leads are intimate with this Headphone, so it gives rock, and heavy metal justice to their recordings.
Conclusion:
I purchased these for $39(They are the only unit left). They are quite the economic monitors. I would recommend these for starters in the live mixing. For musicality, I would also recommend it but just be warned of the Treble cannons, and some comfort issues. Acoustic Modding Work is quite interesting with these since they are quite modular on the pads but the insides has less room for modding work so for sure they cannot be the next T50RP in terms of modifiabilty. One thing is for sure, The Price to Performance Ratio is excellent for these monitoring cans.
I will have to deal with the pinkiness of these monitors, I really want to be lowkey with black, white or gray color(They are the only ones available, but the sound really grits my heart). But who knows, girls might find me sexy with this pinky
