The Audiocular Spark Hi-Res portable DAC and amp is a compact, budget-friendly device powered by the flagship CX31993 DAC chip and MAX97220 amplifier, delivering studio-quality audio with clear vocals, rich bass, and detailed highs. It provides up to 63mW power output suitable for most IEMs and headphones, improving volume levels and sound clarity significantly over phone. Its solid build quality, portability, and seamless Type-C to 3.5mm compatibility, make it on-the-go music listening experience for me. Some minor background hiss may be audible with sensitive earphones, but overall it offers excellent value for a high-resolution audio upgrade at a very affordable price. This DAC+amp is very good option to be considered under 1,000 rupees, balancing sound quality, convenience, and durability effectively
Works like a charm!
It is good for the budget
In the budget category, these offers LDAC and planar magnetic drivers for truly clean, balanced sound and a unique design. It may have less extra features than other earbuds, but its core audio quality is far better than the usual bass-heavy options.
This is a really great product and the build quality is phenomenal. Thank you guys.
Good value for budget audiophile gear.🔥🔥🔥
smooth tuning, and elegant aesthetics. It excels in vocal clarity, offers a pleasingly balanced sound, and feels premium. ❤️🔥
its been 10 days and so far the dac is working fine and i hope it ll work for the long term. The package arrived in great condition and on time, the quality seems great given that it is audiocular.
It just adds a soul to your IEM's. Totally worth the purchase.
It's a best audio earphone I bought , immersive and clear vocal audio experience and using as a EDC for every journey
I order this IEM after watching too many videos on youtube. I was using apple's wired earphone before. so I was finding for IEM that can be my daily driver. For me these are natural sounding IEMs. I enjoyed them a lot. even lot of my colleagues have tried it. Got positive reviews from them also. The bass in this IEM is not overpowering treble and vocals. They are well tuned. if you want to change the tuning (want more bass) you can do it from tanchjim app(supported only for TYPE C). I have tried it there are so many other presets to. I have tried changing its tuning to simgot Supermix 4 so the bass vocal and treble get boosted. You can consider this as your first IEM.
Thanks to Audio Store I got my iem 3 days earlier and without any damage.
Very helpful in maintaining type C cable
Build quality is top notch. It's heavy but not uncomfortable. Coming to sound it has balanced sound signature with slight emphasis on treble.
Excellent studio quality clear natural audio with good enough bass, well-balanced thanks to the audio store team and Pritaam Halpawat sir, great customer service, and 100% authentic genuine products.
Great
