• The IEM itself
• 2 braided cables (I'm quite tired of Simgot cables in this price range, they feel like sticky aquarium hoses)

==CONCLUSION==​

• If you're looking for an IEM with a good single DD configuration for around $85, the EA500LM might be the best choice with a myriad of options like modular nozzles that can provide significant sound changes.
• The fun tuning with engaging power makes it very suitable for all-around songs. The quantity and quality of bass and treble aspects are clean, neutral, and coherent, making it a strong point of this IEM despite having slightly recessed vocals and not being the best for micro-detail.

Beauty Requires Investment​

At first, I was reluctant to review it since it hasn’t gained much traction in Indonesia. But after seeing the IEM, it looked stunning, and the driver configuration intrigued me with the inclusion of a micro planar driver. Does that mean it's a smaller planar driver? I’m not sure of the difference.
Let's dive in… Celest Phoenixcall.

==STRAIGHT TO THE POINT==​

Unboxing:
Honestly, I was very surprised during the unboxing. Besides the cool box with its asymmetric lid, you are immediately greeted with information about the origin of the name Phoenixcall, and you can see the IEMs with their stunning faceplates. The unboxing experience is very satisfying. Included are:

• The IEMs
• 8 braided cable with 3.5mm jack
• 2 types of Celest eartips with 3 sizes each (the standard Celest eartips are quite usable and decent in quality)
• Carrying case with a sticky zipper
• Phoenix keychain
• Manual

​

Fitting:
These IEMs are very beautiful!! With transparent resin shells, you can see the driver configuration inside. The shiny, star-studded faceplate adds to the beauty, paired with the white cable. With a fairly large body and long nozzle, these IEMs might be tricky to fit in some ears, especially needing the right eartips. But in my large ear canals, they fit perfectly fine.

Bass:
This IEM has punchy bass from the single DD that’s quite deep but with fast speed. What I love is the punchy bass that feels like it hits the back of my head and is great for headbanging. The kick drum feels more impactful.
For sub-bass, Phoenixcall has a long rumble that adds a sense of width, dynamics, and grandeur to the music. Unfortunately, in some songs, I find the sub-bass sound a bit unclear and slightly distracting.

Mid:
This is where the IEM becomes somewhat segmented for certain people. The vocals feel heavier, meaning male vocals sound good, but female high notes seem a bit restrained, though they add soul to certain songs like old-school or slow acoustic tracks.
The timbre of the mid-range lacks crispness, and the snare drum sounds a bit shy, making it feel like listening to a grown-up Justin Bieber who hasn't yet hit puberty.

Treble:
The treble is tuned tame with just enough power. The limited capacity sometimes feels unadventurous. Moreover, the upper treble sounds metallic and unnatural, which can be quite bothersome in songs requiring intense sparkling and crispness. Additionally, the upper treble feels cut off during sparkling segments.

Clarity:
The metallic upper treble is unpleasant. The micro details are not well rendered and feel shy.

Soundstage:
This is one of the plus points for this IEM. It's spacious and wide, with the added sub-bass rumble enhancing the grandeur.

Imaging:
The punchy bass overshadows the treble position, resulting in less than optimal separation. In some songs, the instruments in the upper mid to treble frequency range feel a bit clustered, with the BA and planar driver configuration lacking cohesion, resulting in subpar imaging.

​

==COMPARISON==​

I was advised to try changing the cable to one with a balanced port. I happened to have a Sena Rinjani cable with a 4.4mm jack and rhodium pins, tested with a Fiio Q15 DAC/AMP. This cable made a noticeable difference, so here we go:

Note: for those in the "cable changes don't matter" sect, that’s fine, I’m just sharing my experience.

Click to expand...

Bass:
With engaging power remaining, the depth of the bass is reduced compared to the stock cable, but it feels more textured. The unclear sub-bass remains unchanged.
Mid:
This is the best part after changing the cable. The sound feels very natural, effortless, and sweet. Not overly wet or thick, but one of the best vocal IEMs I’ve heard. The only downside is its central presentation might feel lacking for vocal enthusiasts.
Treble:
More pronounced power, no longer shy. Still with a tame tone but slightly more sparkling, though the extended treble remains cut off. Unfortunately, the metallic upper treble is still present in some songs.
Clarity, Soundstage, Imaging:
The same as before changing the cable.

​

==CONCLUSION==​

• One of the IEMs with the best unboxing experience and looks I’ve ever tried.
• Bass and sub-bass are the main aspects of this IEM, combined with a grand soundstage. Unfortunately, the mid-range is quite segmented for some ears, and the treble is less engaging, making the timbre feel less natural, which can be a consideration before purchasing this IEM.
• Changing to a balanced cable can be a solution I’ve proven to enhance the mid and treble aspects of this IEM.
• Celest's unique tuning might either be perfect or unsuitable for some ears.

That’s all.
Trust your own ears.
Bye.

One Step Closer to the Surface of the Rabbit Hole​

I think I remember when this IEM first came out around late 2022 and started to hype up in early 2023, it had quite a bit of enthusiasm from the Indonesian community. This review is a bit late, but well, because I was given the opportunity and I just wanted to, so I decided to dive into it.
As the caption of an Instagram post about engagement says, "One Step Closer," it perfectly describes this IEM. One step closer to diving into the "rabbit hole" of the audiophile world, wherever its origin is... sigh...

Anyway... TinHifi C2.

My IEM recommendation around 500 thousand rupiah?
New to this hobby, which IEM should I buy?
Just want to read the review.

- TinHifi C2

**==STRAIGHT TO THE POINT==**​

**Unboxing:**
For an IEM around $30 or under 500 thousand rupiah, the unboxing experience is minimal, nothing special or wow. But when I first opened it and saw the IEM shell, I thought it looked pretty good xixixi. It includes:

• The IEM itself (already fitted with a pair of ear tips)
• Ear tips (there are about 2 types of ear tips with 3 sizes each. It's quite annoying because all the ear tips are combined into 1 plastic, so it's a bit difficult to differentiate)
• The cable (The first time I saw it, I immediately touched my chest because it's so awful. I thought the Simgot EW200 had the worst IEM cable, but this one is even worse)
• User manual

**Fitting:**
An IEM made from some kind of metal, matte gray finish with shiny ear tips reminiscent of stainless steel. It has a single Dynamic Driver configuration with a standard-sized body for IEMs in a similar price range. It has slightly longer nozzles, but with a size that I think is average, so it shouldn't be a problem for most people's ears. The available ear tips are, in my opinion, just "okay" and can still be used for entry-level friends who don't have their favorite stock ear tips. And what I like is that there are wide bore sizes, so they're my favorite.

**Bass:**
Neutral and soft. That's the most accurate phrase to describe the low-frequency aspect of the Tin C2. Produced by the dynamic driver it has, we can enjoy the thumpy bass hits and the rumbling sub-bass. From an entry-level POV, I'm sure you'll feel quite happy with the sound you hear even though the perceived power is just enough. But there are some weaknesses, such as the very minimal texture of the bass with shallow thumps, so it doesn't feel lively. Then, the sub-bass rumble it produces is very fast and lacks dynamics, so it feels very breathless and has minimal energetic rumble. Also, I feel that the sound from the sub-bass lacks clarity, so you can hear a "bzztt" sound in its rumble tail. If entry-level friends are hoping this IEM is for bass heads, they are mistaken.

**Mid:**
Forward but dry. Although the vocal sound is presented more forward than other aspects, the vocals produced have a problem that I find disturbing. For the upper mid part, especially the male voices sound dry, which is disturbing, so it feels like you want to give the singer a drink because their throat sounds very dry. Also, the sound feels thinner, so the energy from the song being performed is less than optimal. In my opinion, songs with high notes in male voices and songs that require heavy vocals will not be optimally performed.

**Treble:**
Clean and Fun. Of all aspects, I like the treble the most. This IEM has clean treble with good micro-detail in its price range. I like it not because this IEM is shining-shimmering-splendid (because it's not at all), but because I appreciate this IEM at this price having clean treble presentation with a fun and neutral sound to listen to. Don't expect a treble tail that's sharp and long because it's relatively short, but it's tuned with a clear presentation, not overshadowed by other aspects, and has sufficient power. For entry-level IEMs, this can be a good starting point for okay treble IMO.

**Clarity:**
The rumble tail from the sub-bass that's not clean sometimes disturbs in some songs. But other than that, all the sounds are clear. Micro-detail clarity isn't the best aspect of this IEM because many micro-details are not presented.

**Soundstage:**
Average. Don't expect "like watching a concert, bro?" because it's definitely not, but you can feel a wide and pleasant stage.

**Imaging:**
There's no impression of a 3D holographic rotation in your head because this IEM has a relatively flat dynamic and minimal dynamic range according to its price range. Each instrument can be pinpointed in terms of sound separation, but for the micro-detail sound produced, it feels stuck with other main instruments.

**Specs:**
Available in the photo, see for yourself.

**==CONCLUSION==** ​

• The neutral sound of the treble tuned with fun and clarity is the main advantage of this IEM. Moreover, with the forward vocal position, it feels more comfortable for jazz and slow acoustic songs.
• However, unfortunately, there are weaknesses in the unclear sub-bass sound and the bass thump that lacks texture and depth. Also, the thin vocals and problems with the upper mid-range sound dry, especially with male singers, which is very torturous in some songs.
• Is this IEM worth it? For entry-level users looking for their first IEM to understand the "surface of the rabbit hole" of this hobby, this IEM could be the right option because the sound it produces reasonably answers the "hi-res sound IEM" from a Counter IEM.

That's all.
Trust your ears.
Goodbye.

• Celest Pandamon 2.0

​

==STRAIGHT TO THE POINT==​

Unboxing:
Similar to its older sibling, the Celest Plutus Beast, the Pandamon 2.0 comes with almost the same accessories, but it lacks the Beast icon hanger, and the case material is of lower quality synthetic leather compared to the Plutus Beast. Inside, you'll find:

• The IEM itself
• 2 types of eartips, each with 3 sizes (Kinera eartips and regular silicone eartips. The quality is quite good for this price range)
• Carrying case (just standard)
• 4.4mm jack cable (I'm not sure if there's an option to purchase with a 3.5mm jack, but this cable type is comfortable to use, although I don't like it much because according to Celest, their cables are better replaced to improve the sound as well)
• User manual

Fitting:
The IEM is small, but in my opinion, the shell material is a bit fragile, perhaps because it's cheap. The nozzles are long and have a somewhat muscular shape, a bit strange and long. It's a bit difficult to fit with premium spinfit w1 eartips because they are slightly large.

Bass:
The SPD (Square Planar Driver) described as a Square Planar Driver, or a planar driver in the shape of a square box, surprisingly offers bass of good quality and quantity for its price range, even slightly better. The bass is deep and punchy, categorized as fast, yet very deep, and you can feel its fun texture and effort, with no sense of muddiness at all.
Initially, when I used this IEM, I felt a slight buzz in the sub-bass. But I remember people saying that SPD drivers need to be Burn-In for at least 48 hours. And it turns out, after Burn-In for about 12 hours, the buzz in the sub-bass was completely gone. The sub-bass with balanced impact and rumble was a bit surprising, it's like listening to sub-bass from a Dynamic Driver, right? Fun and quite energetic, even though it's not the typical long rumble.

Mid:
From the moment I tried this IEM until now, there's one thing I've noticed because it's so pleasant, namely, the Mid part, which is smooth and forward. This IEM has smooth and fairly airy vocals, but doesn't sound hollow, so the resulting sound has its own distinctive and enjoyable characteristics. TBH, for $59, this IEM is quite surprising in terms of its vocal as one of the best vocal IEMs for $59. It's bring neutral vocal signature that become the star of this IEM.

Treble:
Not Metallic! That's the impression I get from this SPD Driver. Previously, I reviewed the Celest Plutus Beast with a Multi-Driver configuration, one of which was an SPD, and I didn't feel any metallic-ness at all.
For the Pandamon 2.0, it has a safe treble tuning, but still supported with good power, so the sense of detail and sparkle can still be enjoyed within reasonable limits in its price range. However, the extended treble tails feel less refined compared to other planar driver IEMs, and the extended treble tails are within a range that tends to be short, so the shining and splendor are less maximal for treble heads.

Clarity:
There's a slight sibilance in the upper mid to treble parts for some songs, but it's still within reasonable limits because the treble is tuned safely.

Soundstage:
Average, a bit above average.

Imaging:
Decent 3D holographic imaging, and you can feel the sound rotation in your head quite well for its price range. You can pinpoint the location of each instrument you hear, but in my opinion, some instruments from the upper mid to treble feel a bit stuck, so the separation is not maximal.

​

Specs:

• Kinera 10x10mm SPD 2.0™ (Square Planar Driver)
• Impedance: 9 Ω
• Sensitivity: 108 dB
• Frequency Response: 20Hz-20kHz
• 5N Copper Silver Plated
• Plug: 3.5mm / 4.4mm Balanced

Although it's not too heavy on the ears, I suggest replacing the cable for better potential and a 4.4mm jack. The use of a DAC/AMP with Warm and Detail characteristics will be very satisfying.

​

==CONCLUSION==​

• Planar drivers, which usually have metallic treble and less natural bass and vocal, in the Pandamon 2.0 can handle all of these aspects quite well while still emphasizing good micro-detail from the planar driver side. Burn-in for at least 12 - 48 hours is a must to enjoy the sound of the Pandamon 2.0 better. Cable replacement can also be tried for those who want to unleash its potential better.
• Is it worth it? For those looking for a small IEM with the distinctive sound and detail of a Planar Driver, the Pandamon 2.0 is the most solid option in this price range. Especially with its impactful bass, non-metallic treble, and smooth vocals.

That's it.
Trust your ears.
Bye.

"The IEM Endgame for me" is a statement I used to believe in until I reached the point where even after defeating the Final Boss, another Final Boss emerges when our game (hobby) gets an update patch (the release of the latest IEM). So, I titled this review "Chapter 1" because this IEM has become the king of clarity and bass texture among single DDs, acknowledged by reviewers worldwide, and surely there will be contenders for its throne when the new chapter begin (new IEM release).​

==STRAIGHTFORWARD REVIEW==​

​

​

• Clarity: As clear as my future.
• Soundstage: For its price, categorized as above average.
• Imaging: A single well-tuned DD provides excellent instrument separation and imaging without any other frequency aspects being obscured. The 3D holographic sensation feels average, meaning the sound doesn't rotate around the head to the fullest extent.

==COMPARISON==​

• Unboxing:

• Fitting:

• Bass:

• Mid:

• Treble:

• Clarity:

• Soundstage:

• Imaging:

==CONCLUSION==​

• Although having high technicality doesn't mean it suits everyone's taste. Sometimes ears also want to be "deceived" by slightly polished sound.
• The technical IE 900, but vocals suffer because it can't deliver maximum performance.
• Is it worth buying? If you're a treble head like me who also seeks the best bass sound supported by a compact IEM body, then your choice is the IE 900. But if you need a fun and engaging sound like the IE 900 but with bass and treble that are more tame, you can try the IE 600.

==THE SOUND I'M LOOKING FOR==​

• Criiinngg treble if possible a bit spicy
• Good quality and quantity bass, but not for bassheads
• Technicality, imaging, and clarity are top-notch
• Wide soundstage
• My Daily Driver: Symphonium Crimson and Kinera Verdandi

• Simgot EM6L
• Letshuoer DZ4

​

==STRAIGHTFORWARD WITHOUT BEATING AROUND THE BUSH==​

• - The IEM itself
• - Carrying case (standard stuff)
• - 3.5mm Jack Cable (the material is not bad like the EW200 cable. still dominated by a plastic-like layer but not sticky and more comfortable. The color is also better. Oh yeah, it's QDC pins, for some people might feel not quite suitable)
• - 3 sizes of eartips (similar to Letshuoer DZ4's eartips, soft silicone with a slightly harder middle part)
• - manual

​

Note: My ear holes and canals are very big and long hahaha. So whatever IEM I use seems comfortable as long as I get the right eartips

Click to expand...

• Clarity: For its price range, this IEM has quite good and clear details. There is no sibilance or hissing sound in any aspect.
• Soundstage: Average and tends to be Intimate. If you expect spaciousness, you definitely won't feel it hahaha.
• Imaging: I was a bit skeptical if the soundstage was narrow the separation would be piled up. Oh, it turns out not! Separation is very good and all instruments can be felt separately. Unfortunately, it doesn't feel like a 3D holographic where the sound rotates in the head because the arrangement is very dense.

• Driver Type: 1DD Dual-Cavity with custom-designed 8mm polymer diaphragm + 4BA.
• Frequency Response: 8Hz-40kHz.
• Effective Frequency Response: 20Hz-20kHz.
• Sensitivity: 119dB/Vrms.
• Impedance: 26Ω±15% (@1kHz).
• Jack Connector: SE 3.5mm gold-plated.
• Capsule Connection Type: 2Pin 0.78mm QDC.
• Capsule Technology: High precision 3D printed resin capsule.
• Cable: High purity silver plated OFC copper cable.

​

=COMPARISON=​

• Unboxing: DZ4 wins slightly, because the case is better. The rest is the same hehe.
• Fitting: Draw. The fitting and materials used are very good in terms of IEM and its cable. It depends on your preference whether you like an IEM with a Matte finish like the DZ4 or Metal like the EM6L
• Bass: DZ4. It has better and deeper power, but the Sub-bass is better in EM6L even though it lacks power.
• Mid: EM6L. Actually, DZ4 has really good vocals and quite balanced with EM6L. But it depends on preference, DZ4 that's bold or EM6L that's airy.
• Trebel: DZ4. If EM6L had better power, I would choose EM6L because its treble is more extended and sparkling.
• Clarity: EM6L. One of the best tunings without any annoying unclear sounds and good micro details.
• Soundstage: DZ4. Clearly DZ4 has a wider soundstage.
• Imaging: DZ4. Feels more 3D holographic.

=CONCLUSION=​

• Once again, Simgot proves that its Dynamic Driver is well tuned. Proven by its impactful, fun, and sufficiently extended Sub-Bass.
• The additional use of 4BA seems to aim to improve the technicality of micro details from its predecessor IEMs. Although tuned very well and coherent with its DD, unfortunately, the tuning on the treble and low bass sides feels less engaging and might be considered loose for some people. Although the sound produced is very clear without any sibilance
• The tuning above makes the vocal aspect feel effortless to stand out in every song played, feels airy and very natural. One of the IEMs with very good vocals in its price range.
• The soundstage, which can be said to be average, will feel just enough and suitable for songs with good recordings
• Is this worth it? For those who like effortless vocals that are good and airy, natural sub-bass rumble, and bass and treble tuning that are quite tame, this IEM is the most suitable choice. Maybe it will be suitable for ballad and Broadway songs that seek the sweetness of their vocals.

==LET'S DIVE IN WITHOUT FURTHER ADO==​

• Clarity: Clear and natural sounding. The super sweet vocals and gently tuned treble are perfect for long listening sessions.
• Imaging: The bass and treble feel slightly distant due to the very forward vocals. This supports a pleasant setup for acoustic songs. Instrument details are well depicted without any sound overlap.
• Soundstage: For its price range, the provided soundstage is average, not very wide but not too intimate either.

​

==SO, WHAT'S THE VERDICT?==​

• For the price, you'll rarely find an IEM with vocals as pleasant as this.
• Natural-sounding treble that is gently tuned but lacks support from micro-details that could be better for its price range.
• The nozzle is quite large.
• Recommendation? This is perfect for acoustic IEMs, no complaints there. Or for listening to melancholic songs all day long. But for other genres or as an all-rounder, it might not be suitable because the treble and bass are too relaxed and I prefer more energetic sounding.

• What's an IEM with a 3DD + 1 Passive Radiator configuration like? (for God's sake, I don't know if this passive radiator is like a car radiator or what. but what's certain is that it moves passively based on the impact of the other 3DDs)
• What's a good IEM for vocals and acoustic music?
• Just want to read a review

==DESIRED SOUND==​

• Crispy treble, with a bit of spice if possible
• Good quality and quantity bass, but not for bassheads
• Technicality, imaging, and clarity are top-notch
• Wide soundstage

==TESTED WITH==​

• Youtube Music
• Tidal
• Hiby M300
• Fiio Q15
• Lenovo Office Laptop (What series)
• Letshuoer DZ4

​

==SAY IT WITHOUT SUGARCOATING==​

• The IEM itself
• Carrying case (The case has a matte finish, smooth, comfortable to hold, and I think it's useful. Although it's not too big inside)
• Cable 3.5mm jack (The cable is similar to the S12 Pro, it has a metallic feel and I have no problem with it at all. It suits its price)
• 2 types of ear tips with 3 sizes each. (Ear tips that suit its price. Useful for those who don't have other ear tips, you can use the ones that come with it)
• Manual

​

• Clarity: The lack of power and sparkling in the upper treble makes it feel less clear. For other parts, there's no problem with micro-detail presentation that can't be complained about in its price range.
• Soundstage: In its price range, it has an above-average soundstage.
• Imaging: The sound feels 3D which is very good and can present instruments and sound separation well. But because of the less clear upper treble, that part feels more recessed.

• Three dynamic drivers + single passive radiator in-ear monitor HIFI earphones.
• Four-way Acoustic Tubes, Two-way Crossover Circuit.
• Semi Open Faceplate Design, A Fusion Of Metal And Resin.
• The drivers are connected to the dual-pin receptacle via a flexible printed circuit (FPC) crossover board.
• Joint Effort With HeyGear, The Leading 3D-Printing Supplier
• Four cores of 216-strands, 0.05mm in diameter silver plated copper cable.
• DZ4 comes with a standard 3.5mm single-ended plug, featuring a standard 0.78mm dual-pin design.
• High precision in 3D Printed chassis production to meet ergonomic principles.
• CNC-milled anodized aluminum casing with semi-open design.

=CONCLUSION=​

• Letshuoer really understands how to make IEMs with minimalist designs that are beautiful and comfortable to use.
• Perfect midrange presentation with good bass and treble tuning is not supported by the minimum sub-bass impact and the recessed upper treble.
• From its pros and cons aspects, Letshuoer seems to target a specific segment for vocal lovers with slow acoustic music genres.
• Is it worth it? If your music genre is mostly like that, I think it's cool. But if not and you still want to buy it, it's okay too, it's your own money haha.

Double The U-Shape Become W-Shape.​

• What is Symphonium Crimson like?
• Upgrade from the Meteor series?
• Who is Symphonium Crimson for?
• Just want to read the review.

• Crisp treble if it can be a bit spicy
• Good quality and quantity bass, but not for bassheads
• Technicality and clarity are top-notch
• Wide soundstage

• Youtube Music
• Tidal
• Hiby M300
• Fiio Q15
• Lenovo Office Laptop (What series)
• Symphonium Crimson
• Symphonium Meteor

• The IEM itself
• 4-braid modular cable 3.5mm and 4.4mm pins (the cable is nice. I really like Symphonium cables with their good finishing and soft material)
• 2 types of eartips with 4 different sizes each (total of 8 eartips)
• Our unit number card (I'm number #079)
• IEM case (yes, a case, because it's metal and it spins. Cool but quite noisy and disturbing to other items when put in a bag)
• Sticker + IEM cleaning brush

• Bass:

• Mid:

• Treble:

• Clarity, Imaging, and Soundstage:

• Specs:

• Bass: overall, Crimson wins among the three. Meteor has a similar tonal but less airy and not as good bass response as Crimson. U4s has an advantage in this regard because although the Crimson driver produces better bass, the Apex module in U4s allows users to adjust the bass intensity.
• Mid: U4s definitely loses in terms of mid. Crimson wins again with smooth, airy, and bold vocals. Meteor is less airy, so its vocals feel too bold for some people.
• Treble: For those who like it spicy? Crimson is the answer. If you want something safer and not over-the-top, go for Meteor. U4s is more flexible because of the Apex module and its V-Shape tonal combination, so it suits the tastes of most people.
• Clarity and Imaging: Crimson is slightly better than U4s, like 11-12. Meteor is at a very good level according to its pricing. But not as high as U4s or Crimson.
• Soundstage: Crimson is airier than U4s because of its W-Shaped tonal, so the signature sound produced by Crimson feels more lively. Meteor tends to be more intimate.

• Oh God, please help my savings from spending too much on this hobby.
• W-Shape and bright IEMs with outstanding technicality and soundstage
• Like Symphonium Meteor or U4s? It seems like Crimson could be one of the options for an upgrade.
• Behind its interesting tonal, the Treble spike may be a bit disturbing for some sensitive people and the slightly larger body of the IEM could also be a consideration for long-term use fitting.
• Always fun to try high-end IEMs (although not yet summit-fi) because their tonal is fun and unique.

==LET’S JUMP INTO IT==​

• According to Hidizs website, the cable for lightning to 14 pro and below is only for direct purchases from Hidizs. If purchased from a distributor/partner, it's still undecided.
• I've discussed with the Hidizs team and suggested changing the USB A converter to a Female USB C to Male USB C cable because the usage of USB C is more common now and it would be more convenient for those who struggle to plug into mobile devices due to casing.
