Very good service

Excellent product. Has improved the performance of my Sony xm5 by leaps and bounds on the Apple products. Also one pairing is good enough for all of them.

First off great speed of delivery from The Audio Store. Literally got them in like 2 days. Genuine quality product.
I upgraded from my Moondrop Harmons, was pairing them with the ibasso dx180. Readup about the Monarch Mark4 and went for them as they had a similar sound signature that I like not too clinical, just the right amount of bass and warm lush vocals. The ability to switch between two sound modes with the built in switch sweetened the deal for me. Sound is amazing built is great. Could hear clear sound separation, clear instrument separation and a much tighter bass compared to the Moondrop Harmons.
What I didn’t like was the case that comes with it and probably the cable they seem to be thick and bland in design against the beautiful aluminium iem case. The fit of the iems was also not an issue although bigger than most fit my ears alright. Provided ear tips are great.
Regret getting them because now I want to unlock their true potential by upgrading my dap :D

First of all I want to thanks TheAudioStore for customer care, well packaging and prompt delivery. Regarding the sound and comfort, I could not gone through all details since I got this only yesterday. Though it is little bulky, I am not feeling much uncomfortable while wiring it. As reviewer says that the quatio is bass forwarded profile maintaining its clarity across all frequency range.

My second iem after the Tangzu wan'er sg 2, and compared to the smooth and vocal tuning on that this is the IEM that's got the energy and the fun tuning going for it. The package feels a bit lacking but the sound makes up for it a lot. Go for this if you want pure sound bliss.

packing, The IEM’s delivery all amazing. loved it
Thank you Sir/ma’am for this product worth every penny on ears

Great sound quality for the price. The bass is punchy, vocals are clear, and overall audio feels well-balanced. The different sound modes in the app make listening more fun and customizable. Definitely a solid Type-C IEM option.

The Audiocular Spark DAC genuinely impressed me with its sound quality and power. The audio is clean, detailed, and well-balanced, with no noticeable noise or distortion. What really stands out is how powerful it is, driving IEMs effortlessly without struggling or sounding thin. Volume headroom is excellent, and the overall listening experience feels punchy and controlled. For its size and price, this DAC delivers far more than expected and is a solid choice for anyone using power-hungry IEMs.

Pretty good and compact Dac at this price range.

Using the KEFINE Delci AE 4.4mm primarily for competitive FPS gaming, and it’s honestly outstanding for the price. The imaging is excellent — footsteps are easy to pinpoint, directional cues are very clear, and separation in busy scenes is impressive. This makes a real difference in games like PUBG, Valorant, and CS where positional audio matters.
The tuning feels very well-suited for competitive play: clean mids, controlled bass that doesn’t mask details, and crisp highs that help with awareness without being overwhelming. Paired with a balanced source, it has plenty of headroom and sounds very resolving.
For under $100, it’s hard to think of anything that comes close in terms of imaging and competitive performance. I’ve had no real complaints using it for long gaming sessions, and it delivers exactly what you’d want from a serious FPS-focused IEM.
If your priority is competitive gaming and positional accuracy, the Delci AE is an easy recommendation in this price range.

Good Sound Clear Trebles And solid build qualityfor the budget.

These are my 3rd pair of IEMs and can't say anything bad about these!

Excellent smooth and balanced sound stage with clear vocals, totally worth it!

Bought these as an upgrade to my iem stock cables, totally worth it!

Excellent build quality and improved sound stage 💯

Writing this review after almost two months of use, I can confidently say this IEM is amazing for the price. It arrived within three days and in perfect condition. Describing the product in such a short review is difficult, but in one line, the sound quality is impressive, though it may vary based on personal taste.
The bass is controlled (not boomy), with good clarity and a balanced V-shaped sound signature. It feels like I am in a mini theater :). I really like this IEM—my IEM journey starts here.

Kefine klean is one of the best iem is this price ❤️❤️💕
