    "Great Earphones, solid all rounder."
    Pros - amazing metal build, attractive, very good clarity of mids and treble, interchangable filters.
    Cons - cable can break very easily, cable frey in earhooks and jack. no detachable cable.
    I dont want to go on forever in this review, but these RHA T20's are some of the best IEMS i have ever used. But! there are always flaws that can be fixed.

    BUILD QUALITY AND DESIGN:

    - stunning metal finish. The housing is made by a metal injection moulding process, which is done hand made at RHA. There is no competitor in build quality for the buds themselves.
    - very good fit in most ears. There is plenty of included eartips to fit almost any ear. In terms of a universal fit, i would give the T20's full marks.
    - colour coded eartips. i know its a minor detail, but it makes putting on the premium IEMS more seamless.
    - the over ear/hook design provides very good isolation. but they are not as isolated as some balanced armature IEMS that I have used.

    Cons:
    - Cable is very likely to get "wear and tear". The first day i recieved this, the spring near the jack broke off. This meant that there was freying on the cables end.
    - There is no detatchable cable!!!. This is a huge frown on RHA, for selling premium and durable IEMS, but the cable is the bottleneck to its lifespan. Would like this on future revisions please.
    - Would prefer a lower profile jack. Preferably the T jacks that run along the side of phones. This the elongated end of cable , makes it bulky and orkward to fit in my pocket.

    SOUND QUALITY

    Very good sound quality, especially for modern dynamic drivers. The mids and treble are very crisp, while also having good punch to the bass. The mids and treble can be refined with the interchangable filters. The bass filters didnt do as much as expected, as i was impressed by the instant change in detail with the other two filters.
    I cannot speak much of the sound quality now, as the T20's are in for repair.

    Overall, the T20's have some solid features. They arent the best professional earphones you can buy for the price, but it has many unique features most IEMS dont. I currently have just recieved the Audio Technica ATH-IM02, and am starting to miss RHA's unique sound signature, good looks and charm. The RHA T20's are amazing in ear, with great sound quality, and can suite any audiophiles tastes, with adjustments in bass, treble and mids.

    EDIT: Extra star, the customer support is really good. If the cable breaks or anything happens to the device, they will gladly replace the earphones for you, this is thanks to their flexible 3 year warranty.

    "Easily the best steal ever "
    Pros - Great quality highs and low range, Build quality is exceptional and ergonomic, comes with customisable treble and bass filters
    Cons - Ear rest is tedious, tad bit heavy (but it grows on you), no detachable cable.
    I was lucky enough to get a pair of the T20 from a friend for a low price (less than half the retail price). Even Though I managed to get it at such a low cost this wasn't taken into fact when writing this review, it comes with a lot of different sized ear tips including comply. The RHA also comes with filters for Bass and Treble for when you prefer some boost on either end. 
     
    I would say overall it is by far the best earphones I have got my hands on yet, I haven't used the filters so I am not able to comment on them. The memory ear rest is not the best build, it is very clumsy and doesn't seem to properly fit the ear, needs to be messed with to stop annoying (Keep in note I have OCD). The weight could be an issue but as mentioned above, you tend to get used to it after a day or two. It tends to get twisted after the Y split but can be avoided at times by zipping it. Other than that, I enjoy it day to day. Overall good buy !
     
    I would recommend this product to anyone who reallys wants to enjoy good quality audio for a price.

    -Introduction-​

    RHA is an interesting company. It has forged its own place within the audiophile world, making a name for itself based on the industrial design language of its products and the generous duration of the warranty that accompanies them. Today I have the privilege of reviewing the T20, RHA’s former flagship IEM. While it’s no longer the pinnacle of what RHA has to offer, it’s certainly still worth taking a look at.
    You can find the T20 for sale on RHA’s official website here, for $240.
    Disclaimer: This review is based upon a sample unit provided to me by a manufacturer or distributor in exchange for my honest opinion and un-edited words. I do not profit in any way from the writing of the review. I would like to thank Marina and Caroline at RHA for sending me this review unit.
    Preference and Bias: Before reading a review, it is worth mentioning that there is no way for a reviewer to objectively pass judgment on the enjoy-ability of a product: such a thing is inherently subjective. Therefore, I find it necessary for you to read and understand what I take a natural liking to and how that might affect my rating of a product.
    My ideal sound signature would be an extended sub-bass with a leveled, but textured, bass. The mids should be slightly less pronounced than the treble, but still ahead of the bass. I prefer a more bright upper range.
    Source: The T20 was powered like so:
    PC optical out-> HifiMe SPDIF 9018 DAC 3.5mm out-> earphones
    or
    AP100 3.5mm out -> earphones
    All music was served as MP3 @320Kbps or as FLAC.

    -Sound Signature-​

    Initial Impressions:
    Silver/Reference filter: Treble has a notable presence. It is transparent, but not biting, raw, or sharp. Mids aren’t too far back, and are rather dynamic within the mix. Bass is slightly boosted, giving the low end of the spectrum a nice weight to it.
    Gold/Treble filter: While the treble filter doesn’t actually decrease the amount of bass being produced, it does make it feel less forward by boosting emphasis to the treble and upper mids. This boost does make the T20 feel a little more precise, and opens up the sound a little bit more. It does not, however, make the treble sibilant or sharp. As a side effect, mids are also slightly pushed back.
    Black/Bass filter:
    The black filter adds a notable amount of sub-bass, with a slight boost to mid-bass. This makes drops deeper, drum kicks harder, and classical concerts more sonorous. While still not at bass-head levels of bass, the T20 does do a good job delivering in both quantity and quality of bass using the black filter, more so than many “warm” and “bassy” IEMs in this price bracket.

    RHA’s official frequency response graph for the T20.​

    Unless otherwise stated, the statements made in the following sections are made with regards to the neutral (silver) filter.
    Treble: Songs used: White FlagMidnight CityOutlands
    As I’d mentioned earlier, treble is quite nicely placed. It is very transparent and well-extended. Impressively enough, it is also very much not sibilant, sharp, or raw, instead adopting an bold, yet respectful presence. This manifests itself as a good level of retrieval and micro-detail placement in songs like White Flag. Treble layers well, and has it’s own dynamics and depth to it. Outlands fairs just as well, as the T20 does a very good job creating a sense of air, separating out the violins well from the rest of the song.
    Hi-hats decay well, and don’t smudge too much into the rest of the upper register.
    Mids: Songs used: Flagpole SittaJacked UpI Am The HighwayGood Life
    Evaluating the mid-range of an IEM is more often than not my favorite part of my reviews, and the T20 feeds my interest well. My songs really do come to life on the T20, as each instrument is distinct, with its own position and depth, which is likely due to the airy feeling the T20 gives to many songs. Interestingly enough, the T20 does not seem to have a large spike around the 1–2KHz range that many IEMs use to boost vocal resolution and clarity. While there is certainly a climb from 1–2KHz up to 5Khz or so, such a incline gently moves the vocals forwards, without making them too commanding of the song.
    Bass: Songs used: LightsGold Dust99 Problems (Hugo Cover)Leave Me
    Even with the reference filter, bass is not at “reference” levels of emphasis. Instead, RHA chose to give the T20 a small boost in mid and sub bass. While audio purists may disagree with that choice, I actually quite enjoy it. It allows songs like Lights to have a very satisfying level of depth and body, without causing songs like Gold Dust and Leave Me to become boomy and messy. In fact, the reference filter still manages to give said songs a meaty bass drop with some excellent sub bass extension.
    Clarity: Songs used: ThroneMap of The ProblimatiqueI’m Not Alright
    The T20 is developed using RHA’s proprietary “dual coil” dynamic drivers. While this may sound fancy (and likely is in practice), the theory behind it isn’t too complex. The “dual coil” refers to a 2-in-1 driver that’s split the transmission coil of the dynamic driver into two separate rings, allowing the driver to divide its workload among the two coils. Thusly, it functions as if it had two dynamic drivers inside, while maintaining a size close to that of single dynamic driver. This technology does show itself when the T20 is pushed quite hard, and it shows itself well. The T20 handled Throne without problem, as it did with I’m Not Alright. No distortion, no noticeable smudging. There was, however, a small amount of lost micro-detail, which is to be expected.
    Sound Stage
    Sound staging is precise. So precise, in fact, that I had what I’d consider to be my first true “3D” sound space experience with it during the intro of Soldier’s Poem by Muse. But further than that, as I’d mentioned earlier in my review, the T20 does a wonderful job creating an airy and spacious stage for the instruments of my songs to play on. Classical songs can take on a symphonic feeling, punk vocalists can scream their hearts out right next to you, and electronic bass drops can immerse you in the chaos that is the modern EDM scene.

    -Packaging / Unboxing-​

    My apologies for the slightly rotated pictures, as the rock I was taking pictures on was not flat.

    -Build-​

    Construction Quality
    RHA did a very good job making the T20 feel sturdy and premium. The polished stainless-steel driver housings look like little metallic jewels, and have a satisfying clack when bounced against one another. The driver housings look to be comprised of two metal parts, joined at a seam roughly in the middle of the housing. While it’s an impressive feat, there seems to have been a slight misstep along the way when my particular unit was manufactured. The seam of my left driver housing is wider than the one on the right driver housing. My suggestion to RHA is to try an make the seam less noticeable, as it would greatly enhance the premium look and feel of the T20.
    However, for those of you who are nervous, fear not. RHA has great customer service and a heft 3 year warranty on their IEMs, so they’ve got you covered.

    Look at the difference in the width of the seams!​

    The cable is made from the typical RHA rubber, but is actually less finicky than the one used on the MA750i, which is a big plus for me. However, it is still quite bodied, and as such, is hard to coil up neatly. Luckily, the included carrying case is large enough to account for the cable’s bad manners.

    The T20’s cable terminates in a gold-plated 3.5mm jack, and is protected by a spring. This gives the T20 (and most other IEMs made by RHA) an industrial, but still premium, feeling. It’s not just a fancy gimmick either. The spring, as well as all the other stress relief systems on the T20, do a very good job protecting the cable from day-to-day mechanical stress.

    Controls
    While my unit does not have inline controls, RHA sells a version that does for $10 more called the T20i.

    Comfort
    Comfort is highly subjective. Everyone has a different bar that an IEM must reach in order to be deemed “comfortable”. Therefore, all I can say is that this section may not be representative of your experiences with this product.
    I find the T20 to be quite comfortable. The insertion depth of the nozzle is farther than the MA750i, and is a little longer than most IEMs I own in general. This lets me get a pretty good seal, even with the stock silicone. The shape of the T20’s driver housings is quite ergonomic, and doesn’t even feel like it’s there most of the time. The cable’s memory wire is also quite good, having an almost perfect balance between pliability and stability. It’s far superior to the implementation of memory wire on the MA750i.
    The memory foam eartips were, however, not very usable for me. It appears as if RHA chose to use generic memory foam instead of genuine Comply eartips. I had a hard time achieving any reasonable insertion depth with them, and found them generally uncomfortable.

    -Accessories-​

    In typical RHA fashion, the T20 comes with a plethora of eartips all placed neatly on a stainless-steel plate. A variety of nine extra sets are included, which encompass standard silicone, double flange, and memory foam eartips.
    I am confused as to why RHA chose to include these particular memory foam eartips, which are not genuine Comply, when lower tier IEMs in RHA’s product line, such as the MA750i, include eartips that are either genuine Comply, or very convincing generic versions. It’s pretty disappointment for me, as I absolutely love memory foam eartips.

    I mentioned earlier that the T20’s case is large enough to fit the unruly rubber cable permanently attached to the T20’s driver housings in it with no issues. Furthermore, there is plenty of space to throw in some extra eartips or the metal filter holder. As an added bonus, the case is a perfect fit for the Hidizs AP100, my current mobile workhorse.

    -Summary-​

    The T20 is a versatile, premium IEM. While fit and finish could use a little work, the T20’s sonic prowess is notable for its price. Listeners looking for a stylish, durable, and comfortable IEM with a small amount of bass emphasis should find great solace in the T20’s warm aural embrace.
