I think the highs are parallel to mids in terms of filter choices. Again, blue is a little brighter and highs are a bit more definitive. Black is darker and extension lacks a little when compared, and red is around between them in terms of quantity. There’s good amount of extension, especially when the blue filters come into play. Blacks create a veil to highs so they go a step away from you, all depends on your preference.
Moving on from filters to actual quality, LZ-A4 continues to shine but a little less than bass again. The bass impresses so much, especially with it’s air and quality, you just can’t appreciate the other parts enough. When I think of the treble, all I can say is there’s no problem for this price. There’s no amazing extension, immense air and amazing timbre, but there’s a little for each of them. This is an all-around IEM (obviously, since you can play with filters night and day) not only in terms of quantity of the frequencies, but also the quality. You will find the LZ-A4 well above average in every aspect and highs are no exception.
Micro details and timbre exceeds this price range and make this IEM a huge competitor even in the mid-fi area. Maybe if I push myself too much to find a small dent, I can say the extension is not at the top level. But that would be not fair to this great piece.
As usual let’s talk about the technical aspects at last and close it up.
Starting with the resolution, I think LZ-A4 is very capable at this regard. When you use a good enough source with good quality files it shows the potential. Stellar performance. You can even dare to compare it with the products that are twice or triple the price. I cannot find a flaw about this area.
The highlight of LZ-A4 is the sound stage and ambiance. I think Lao Zhung intented to create a monitor which gives a stereo system feeling. Of course you can never actually get that in any headphone or IEM, but I mean the “feeling”. It just feels so wide and tall. You understand that when you try to close the back filters with your hands. The sound immediately becomes the traditional closed IEM sound. Great job by LZ to come up with this kind of sound with such a low cost. I think no other IEM can give this feeling at this price, and even the expensive ones maybe.
Separation is not at the top of course, and that’s hard to achieve in any monitor, especially at this range. But I’m going to repeat, LZ-A4 has every kind of quality to some extent that can make you completely satisfied. You simply cannot regret it. With blue filters,the vocals have a good seperation from other sections of the sound so consider that. The separation and layering of the bass is simply fantastic, maybe except it has a focus on subbass and midbass being behind. Yet, that would be just nitpicking.
There’s no sibilance that I’ve encountered. That’s another plus to LZ-A4. Whatever filters you choose, the sound is never harsh or aggressive.
And lastly, it’s very easy to drive it.
What more can one ask?
Simply put, LZ-A4 is the BOMB. The sound is kind of out of your head thanks to the great sound stage and speaker feeling, with a non-aggressive smooth sound with a tremendous bass. The mids and highs are maybe not quite as impressive as the bass, but still very coherent and high level for the cost. It combines these with nearly unlimited options for altering the sound, a good build quality and accessory package. And this was the first time that I liked a IEM with filtering options.
This is the Landing Zone for the people who want a great sound stage, smooth sound and great bass coming with a low cost.
Until next time.
