A few days back I posted my review of the Legacy 4 on Linsouls product page.
My review titled "Budget End Game" as well as link to buy below;
I want to add my review onto the Linsoul forum, so I will reiterate my points here.
After more listening and burn in, my thoughts remained unchanged. For my personal listening, I feel this is one of the best sub $200 IEMs on the market right now. Going forward, do keep in mind my pair of Legacy 4 is paired with the EST cable with the tuning switches set to default.
The packaging is superb and overkill at the same time. It's the type of presentation expected of more expensive IEMs, but seeing this in a sub $200 IEM is definitely a welcomed addition.
For the fit, I found myself using smaller sized tips than what I would with most IEMs. I prefer deeper insertions with the Legacy 4 and found the Spinfit 145 medium worked best for my ears. I tip rolled Final Audio E types, Spiral Dots, Xelastecs, Starlines and a bunch of wide bores from various IEMs.
The shells are relatively compact and have that pseudo custom shell design. They are also very lightweight.
Their lightness, compactness and ergonomic design makes for a very comfortable fit.
The overall tonality of this IEM is a stand out feature for me. I generally like slightly warm v shaped signatures and this IEM hits the spot.
I prefer the sound with the EST upgraded balanced cable and noted that there was added warmth. Low end became a bit more impactful and the mids gained a bit more body.
Sub bass has more emphasis than the mid bass. There's good impact, speed and texture.
Lower mids are fairly laid back, with the upper mids being a bit more lively.
The liveliness carries through the treble with good airiness.
On the technicality front, these IEMS fare very well.
Detail retrieval is superb with adequate macro and micro details.
Timbre is pretty solid throughout the frequency range. I found timbre to be the most natural when using Spinfits.
I am very picky when it comes to percussion and these have been a pleasure to listen to.
Sounstage is above average. The Legacy 4 has above average width, good sense of height and also great depth and layering. Imaging is superb on this set. It's easier for me to pinpoint instruments than on any other sub $200 set I own.
For comparisons sake, the closest IEM I own in this price bracket is the NF Audio NM2+.
NM2+ has a more holographic soundstage, however the L4 does have more precise imaging.
I was surprised to find I prefer the overall timbre more on the Legacy 4 (although very tip dependant).
The NM2+ does have more natural vocals however.
To conclude... This set has exceeded my expectations. Although I haven't owned many IEMS between the $150 - $200 range, this is the best sub $200 set I have owned. ThieAudio experimented with a new 8mm dynamic driver in the Legacy 4 and it's definitely paid off.
I'm looking forward to see what Linsoul and ThieAudio has planned for 2021.
These thoughts and opinions are my own, but I'm interested to hear what others have to say also.
