Today I'll be looking at one of my most wanted and eluded IEMs, the Unique Melody Red Halo FE. With the help of Andrew and Musicteck/UM I was finally able to get my hands on a pair. You can find the rest of the Unique Melody products available on Musicteck at https://shop.musicteck.com/collections/um-unique-melody.
On this review I'm going to jump right into things, as this wasn't a purchased I fully intended to make but saw an opportunity and jumped at it.
The package comes in a nice silver outer box which contains the typical UM magnetic clasp top with bottom drawer design. Contained in the top portion is your Dignis leather case with your cable, cable clasp and the Red Halo FE. The bottom drawer contains your accessories to include extra filters for the twist off nozzle, UM stock silicone tips, other sizes of Azla elastecs, a(nother) cable clip, microfiber cloth and your ownership/serial# card.
If I were to deduct any points it would be here. The Red Halo FE share the same build quality and aesthetics with my other favorite UM IEM, the Mest Indigo and sadly it is also subject to the same faults and flaws. The IEM is beautiful, fits fantastically for me with a near "custom" fit easily fitting flush against my ear without any discomfort or becoming displaced over time. Now for the part where they suffer from the same potential problems as the Indigo, the metal band surrounding the face plate can feel a little flimsy or frail. Other than that, fantastic fit and quality, shells feel durable and well made while still being light and comfortable.
Cable: The stock PWA Bright Fire (Atilla Shielding) is a cable that is touted as a high end cable, and it definitely has a great sound when paired with the Red Halo FE but it has that distinct PWA very mild bloom to it (luckily it is barely present on the Red Halo due to how technically adept it is, but it's there if you listen hard enough). As for aesthetics, it's gorgeous and matches the IEM perfectly, aside from the orange, a weird choice, I'd personally have went with a gold or rose goldish color to match the metal frame around the IEMs faceplate. In terms of ergonomics, considering the shielding and absolutely abhorrent paracord, it's pleasantly "not that bad". However, as all pwa paracord cables, it twists and turns and stays that way, it can be highly frustrating when moving your source around to suddenly realize your cable is now in 20 different directions and coils. I didn't get much of a chance to cable roll the Red Halo as out of my cables available, I did find this the best pairing, so at least it has that going for it.
Timbre: This is one of the areas the Red Halo excels at. All instruments from sub bass to treble sound incredibly natural and coherent (a huge plus from an all BA implementation). Piano keys and violins are standouts as often IEMs can make these sound unnatural or plain wrong when not well implemented. This is a set I'd easily recommend to anyone who loves classical and similar genres but it also does well with rock and symphonic metal.
Dynamics/Transients: As expected of an all BA set with a BCD to boot, the speed of these drives is absolutely top notch, they are able to keep pace with even the most complex music passages and never miss a beat. The BCD enhances the tactility of both, despite being quick, there's still that rumble and punch to the sound similar to a DD. While the dynamics of this set are great, they do fall short of a tribrid implementation or especially a quadbrid like the Indigo.
To keep a more "apples to apples" comparison, my only other BA bass set I've had a long enough period of time with to truly compare is the Nostalgia Audio Tesseract. Both are distinctly BA, very quick and accurate sound but the Tesseract is slower than the RH. The Tesseract is also much more heavily textured (for those familiar with the Ronin, less than Ronin but more than Mentor, in my brief experience with both of those IEMs). In terms of rumble and punch, due to the BCD the RH is the clear winner. The Red Halo also has much less mid bass emphasis where the Tesseract has more, leading to a much warmer tonality than the Red Halo. As a fan of more technical, brighter IEMs, the Red Halo is much preferred to the Tesseract, despite my love for that IEM as well.
When compared to the Tesseract, the warmth of the Tesseract really begins to show through the vocal presentation. There is more air due to the ESTs and overall configuration but detail and tonality is in favor of the Red Halo. The mids are cleaner and have a much more natural tonality than the Tesseract does, while the Tesseract is easily one of the best BA/EST combinations I've heard it simply doesn't compete with the Red Halo. These truly are the best mids oriented set I've heard to date.
As for comparisons to the Indigo, hilariously enough, it's again VERY similar despite the driver differences. There is a noticeable difference in air, with the advantage clearly going to the Indigos ESTs and a slightly better tonality but they are not far off. The Tesseract is the airiest IEM i've ever heard, even pushing past the Ragnar in many ways but it lacks the extension that the Red Halo has, but the RH is slightly clearer, which I'll again attribute to the BCD enhanced imaging and resolution.

Packaging
The packaging is pretty "standard Unique Melody" here, if you've ever unboxed the Multiverse Mentor, Indigo, etc. you've seen and experienced this. That's not to say it's a poor experience, it's more of a mental thing that an IEM nearly 1/3rd the price of these has the same unboxing experience, but UM found something that worked and has stuck with it and it's hard to fault them on it as it is a nice experience.The package comes in a nice silver outer box which contains the typical UM magnetic clasp top with bottom drawer design.

Preface
All testing for the Red Halo FE and comparisons were done using the iBasso DX320 max, low gain, volume matched (to the best of my ability) with ultimate mode on and fast roll-off filter. The Red Halo FE was paired with it's stock PWA Bright Fire (Atilla Shielded) cable and Divinus Velvet ear tips. Keep note that the DX320 max is a bass leaning source, so that could skew impressions vs other users on the bass, even when paired with other sources such as the SP3K and N7 I did not feel the bass to be lacking or otherwise poor quality.Technicalities
Soundstage/Imaging/Resolution: I found the soundstage of the Red Halo FE to be rather large and spherical but on the smaller side compared to other IEMs, but when changing sources I did notice that it had a drastically larger (similar to others such as the Indigo and Nostalgia Audio Tesseract but still smaller). The Red Halos mid focus is the driver behind this smaller stage as in order to get the flow and quality via boosting the upper mids, it causes the stage to shrink relatively. Compared to the Noble Audio Ragnar, the stage is much smaller and not near the holographic nature of the Ragnar. The imaging and resolution are a touch above even the Indigo, thanks to the new BCD, all sounds are well placed even in the elusive top left/right and bottom left/right which many IEMs leave empty. Cymbals and others sound extremely well placed, just in front of the drums but a touch behind vocals. This set is easily the most coherent and adept in the imaging department. The superb imaging lends itself to the resolution as all instruments are easily separated and clear against a black background.
Timbre: This is one of the areas the Red Halo excels at. All instruments from sub bass to treble sound incredibly natural and coherent (a huge plus from an all BA implementation). Piano keys and violins are standouts as often IEMs can make these sound unnatural or plain wrong when not well implemented. This is a set I'd easily recommend to anyone who loves classical and similar genres but it also does well with rock and symphonic metal.
Dynamics/Transients: As expected of an all BA set with a BCD to boot, the speed of these drives is absolutely top notch, they are able to keep pace with even the most complex music passages and never miss a beat. The BCD enhances the tactility of both, despite being quick, there's still that rumble and punch to the sound similar to a DD. While the dynamics of this set are great, they do fall short of a tribrid implementation or especially a quadbrid like the Indigo.
Sound Profile
Bass:
I'll be clear from the start of this, I am FAR from a bass head, I enjoy lean, very high quality, quick bass that has no bloat, bleed or overlap into any other frequency, even sub to mid bass is a no go for me. For this reason, my favorite IEM is still the Viking Ragnar with both the Indigo and Red Halo FE right up there with it. The red halo actually shares a lot in common in the bass area with the Indigo. It is quick, controlled, concise and incredibly clean and accurate sounding, that's why despite this being a mid/vocal leaning set, it even works well with rock and metal tracks due to how well it articulates the bass. I attribute a lot of this quality to the BCD as if you really let get a good fit where these sit flat against your ear you can feel the tactile response of the bcd. There is little reverb but plenty of depth, rumble and punch to the overall presentation. While the Indigo is decidedly DD bass, it is one of the fastest transient DD bass I've ever experienced (even against the Ragnar) and that's where these two sets can sound very similar in their bass presentation, with the only two real "wins" for the indigo going to timbre and air movement, which a DD simply can't be beat at. No fault of the RH, as it truly is an outstanding bass presentation given an all BA build.Bass:
To keep a more "apples to apples" comparison, my only other BA bass set I've had a long enough period of time with to truly compare is the Nostalgia Audio Tesseract. Both are distinctly BA, very quick and accurate sound but the Tesseract is slower than the RH. The Tesseract is also much more heavily textured (for those familiar with the Ronin, less than Ronin but more than Mentor, in my brief experience with both of those IEMs).

As a fan of more technical, brighter IEMs, the Red Halo is much preferred to the Tesseract, despite my love for that IEM as well.
Mids:
Red Halos speciality, bread and butter, star of the show (I could go on but it'd be redundant). The mids aren't overly forward like the EE Odin or other "shouty" iems but they are slightly elevated. Normally with this elevation comes a slight loss in detail and staging but with these the only perceivable loss is in the soundstage width (this is standard, any IEM with a mid focus is going to lose soundstage as a result). However there are loads of details here and female vocals are definitely a stand out for the Red Halo. The main feature is the cohesive flow of the mids throughout. There is air but at the same time the vocal presentation will feel like there are no gaps or fillers, just a natural cohesion to everything that flows like butter without being smooth or losing detail. The tonality of the mids is similar to the Indigo but the Indigo has much more air between and lacks that distinct flow. These stand out with female acoustic performances, such as The Pretty Reckless' 25 (Acoustic), this song is an excellent example of what these IEMs are capable of.When compared to the Tesseract, the warmth of the Tesseract really begins to show through the vocal presentation. There is more air due to the ESTs and overall configuration but detail and tonality is in favor of the Red Halo. The mids are cleaner and have a much more natural tonality than the Tesseract does, while the Tesseract is easily one of the best BA/EST combinations I've heard it simply doesn't compete with the Red Halo. These truly are the best mids oriented set I've heard to date.
Treble:
Anyone that has read my reviews or any of my posts, know this is where I'd likely kill any IEM out of my collection quickly if it didn't perform well. Luckily the Red Halo performs superbly, with a minor note that some people may not like. The treble is extremely well extended, bright and sparkly BUT it can be a little splashy at times with cymbals, not overly so that it does not sound realistic to the type of cymbal being used. Overall the presentation is excellent but I'm fully aware that not everyone's hearing or ears are as receptive to treble or aforementioned splashiness as my own is. The treble always remained in the perfect position within the soundstage and was extraordinarily imaged and untainted by any bleed from the upper mids (like odin). It is as clear and incisive as the rest of the FR without ever being fatiguing (for me, as I said, high tolerance). It is bright for a BA set, those who own the mentor may see some similarities here but, off memory, I found the presentation of the RH to be a step above the MM.As for comparisons to the Indigo, hilariously enough, it's again VERY similar despite the driver differences. There is a noticeable difference in air, with the advantage clearly going to the Indigos ESTs and a slightly better tonality but they are not far off. The Tesseract is the airiest IEM i've ever heard, even pushing past the Ragnar in many ways but it lacks the extension that the Red Halo has, but the RH is slightly clearer, which I'll again attribute to the BCD enhanced imaging and resolution.
Closing:
The Red Halo is one of those specialty sets which also manages to perform excellently outside of it's main focus, leading it to be an excellent contender for a one and done IEM that most aren't able to achieve. As I mentioned throughout, there are many similarities to the UM Mest Indigo, and for someone who wants a little less mid focus, DD Bass and EST treble but a similar tone as a top end set such as this, the Indigo is a great option. The biggest loss is that distinct and beautiful flow of the mid range and vocals which, to date, is completely uncontested. I simply adore this set and it is now tied for my favorite IEM with the Ragnar (Treble), Indigo (All-rounder/bass) and now the Red Halo (Mids!). These 3 together are a true trifecta (pun intended, for those that know) of end-game.Thank you for reading and hope you enjoyed!
