Aroma Audio is quite a young company, founded in 2015 has an independent R & D and design department dedicated to the design and development of portable and desktop audio product.

Talking with Antony, marketing manager of Aroma Audio, I understood their philosophy and the origin of their brand name: “Our philosophy is to make the sound as like as the variations of aroma.

Our team members are experienced in audio products. From the perspective of market demand, we create unique products to meet consumer expectations by our philosophy”.

This company received quite a good response in the audiophile community both for their desktop amp both for their Witch Girl IEM models. Now they released their new Musical Box headphones with these three models:

EARLY, TWINS AND YAO. Today I am going to review TWINS model with 7 armature units.
Time ago, I reviewed their Yao model, this is the link to the article:

Main differences between their Witch Girl IEMs and Musical Box Series: “Witch series has a more pop music style, on the other side, this new Musical Box series is more like England style and so, has a more mature reproduction”.

TWINS unit was sent me for the purpose of this review, I am not affiliated with the company and all observations and opinions will be only my own. Would like to thanks Aroma team for sending me this unit giving me the opportunity to test such a great product.
Aroma Audio is still a small company, but I am really impressed on how their products have such a premium build quality and audiophile sound. They spent a lot of resources in producing this Musical Box series, so will not give a lot of space for reviewers and marketing. From my experience, both their Twins and Yao can easily compete with other premium and more famous companies out there, so really hope they will obtain more visibility worldwide.




PACKAGING: Since both their Yao and Twins have the same package and build quality, I will share the same I wrote for my Yao article.
the musical box packaging is really nice and particular: a wooden case that is really cool.
In the wooden case you can find warranty card, instruction manual ( instruction explaining how attach the cable to the earphones in the correct way), Acoustune original silicon tips, hard aluminium case, soft pouch and obviously TWINS IEM with a black standard cable.


Build quality seems very solid: the shell is made up of transparent acrylic and the faceplate of metal material. I have to admit that TWINS model, as you can see in the images I attached to this review, is a really nice looking IEM.
Comfort wise TWINS IEM is very comfortable thanks to its rounded shape and nozzle angle; it’s lightweight considering that mounts 7 drivers and I was able to find a perfect fit with Acoustune silicon eartips out of the box.
Speaking of isolation, it is very good in this department and if you can find the right eartips you will enjoy your playlist without any annoying external noise.

SOUND: Aroma Audio Twins shares the same philosophy at the base of Yao model: sound with great dynamic ,tempo and musicality, but has a totally different sound signature. Twins has overall a good balance of neutral and clean sound, never sounding too thin or harsh. Bass, like for Yao, is not too much strong, but is capable to give good musicality to the scene. Sub bass is very quick and fast with natural decay. Mid bass gives the right amount of body, but is always natural never warming up too much the music. Overall Twins is capable to show a natural and audiophile bass response never resulting exaggerated.
Voices have good body and realism, thanks to the clean nature of this IEM, female voices are rendered with great accuracy and definition. Treble response is excellent: with great extension, gives a natural and airy sound. Twins is capable to give you good amount of sparkles, but never resulting too much harsh and fatiguing. Overall this IEM has a great fun and enjoyable sound, but still refined and detailed.
Soundstage is very wide and you can enjoy an out of the head sound with the right tracks.


On the external faceplates this IEM has a switch that can be used to change the overall sound signature: with the switch up, the IEM has a more reference and correct sound, but if you love musicality can result a bit boring( it is not my case). With the switch down, Twins will give you a more fun signature, with more bass quantity and a wider soundstage and so with increased loudness. I usually want that my IEM should sound more neutral possible, so I really loved the sound with the switch up.

Dynamic is very good and so is instrument separation.

Thanks to its low impedance, Twins is quite easy to drive( I usually set the volume bat at 60 with my ak Kann in low gain).


TWINS WITH OPUS 1S: Opus will give you a more organic sound with a full bodied and punchy bass response. Voices are rendered with more body and warmth. Soundstage is quite good and left/right channel separation is great. Opus 1s can drive quite easy this IEM in low gain.

TWINS WITH AK KANN: Astell and Kern KANN will give you a great musicality and enjoyable sound. Bass is not strong and punchy like Opus 1s, but adds a good mid bass emphasis. Voices are rendered very good with great realism and timbre. AK kann has more liquid voice reproduction, on the other side Opus 1s a more organic. Treble is a bit smooth with this DAP, but still defined and extended. Soundstage is great with a nice holographic space around you, in particular if connected in balanced mode( I truly suggest you to upgrade to a nice aftermarket cable like PW audio Saladin to improve tonality and soundstage).


AROMA AUDIO TWINS VS AROMA AUDIO YAO: Twins has a more clean sound signature, capable to give a more airy reproduction. On the other side Yao, has a touch more warmth, with a more mid-bass presence. Vocals on Yao, have incredible realism, so if you are a vocal lower I truly suggest Yao. Twins has a more fun signature, with better clarity and sparkles( in particular if used with switch down).
For me, Twins is a great IEM for its price, but Yao is capable to give you better emotions and realism, so I consider Yao a special IEM.

TWINS VS INEAR SD5: SD5 has a more thin sound, with great female vocals, but can result a bit fatiguing. On the other side, Twins will give you more musicality and better dynamic. Bass on SD5 has more impact, but can sound a bit artificial, on the other side Twins has a more audiophile tuning with a faster and more articulate bass response. Soundstage on Twins is wider, but SD5 is capable to provide a more holographic space around you.

TWINS VS UNIQUE MELODY MIRACLE V2: UM has a more full bodied sound. Bass is stronger and punchier. On the other side twins shows a more natural and audiophile approach to the music. Vocal are well rendered on both of these IEMs, but Twins is capable to give you a more refined female vocals. Soundstage is wider on Aroma Audio Twins, with a better instrument separation. Overall, Miracle will give you a more full bodied sound, on the other side Twins will give you more treble resolution and airy sound.

TWINS VS HEIR AUDIO 10.0: Twins has more clean sound signature, with better definition. Bass on HEIR 10.0 has more body with more impact and rumble. Voices on heir 10.0 can result a bit nasal, on the other side Twins will give you great clarity and transparency. Soundstage is great on both of these IEM, but Twins has a bit wider stage.
