Fosi Audio MC351 2.1-Channel Bluetooth Power Amplifier With DAC For Speakers & Subwoofers
After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative options 1. connect using Portronics Bridge Y USB 3.0 to Type C OTG Adaptor via USB A. 2. Use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inch
Some online product selling giants didn't understand how to package product because it delegate and wants to handle with care and I really appreciate your customer support thank you great product delivery app in reasonable rate
It’s a neat dongle with crisp sounding music, it’s on a brighter side of music
one of the best earbuds in this price range.
As a beginner audiophile I did research on all budget IEMs but this KZ EDC Pro stood out in all reviews as best and most affordable no-nonsense IEM without distortion in sound output that drew my attention to it. And I am glad I made the choice, this deserves every bit of praise for the price & sound output better than my 5000INR TWS from reputed brands, a little bit EQ Tweaks just enhances the experience multifold... Must but for those who looking for affordable yet best sounding wired earphones/IEM. Brilliant build and sound quality for the price. A Must buy on a tight budget, and Thanks to audiostore for delivering package before scheduled delivery time.
Great DAC for the price in terms of build and aesthetic. When paired with a good IEM definitely makes the experience worth investing. Just go for it, must buy for a beginner/intermediate audiophile...!
Easy blind buy for the price. Most recommended set of iems if you're new to the iem community and are looking for something under 5000 rupees. Sounds clean and has a lot of customisation options with app support.
good sound and clear even without the dac and anything haven't tuned anything still clear sound!
After having owned a few kilo-buck IEMs, I was prepared to get something that was insane and probably endgame and rightly so Pritam sir recommended the FIR audio Xenon 6 and thus deep dived into this and I am sure this would be the end game IEM for me.
The XE6 is so wonderfully crafted looks like piece of jewelry and although a large IEM it is very comfortable for me for long sessions.
It sounded good from the start and was really different from the other IEMs. It started to sound even better and grew on to be the best I ever heard after listening to it for longer. I paired with Astell&Kern SP3000T and Hiby rs8 II and with desktop DAC Amps (FiiO K19, Topping D70. A70, Hifiman R2R and Xduoo TA 22) and the immersive, warm, musical and soundstage that filled my head all over. The sub bass is where it stands out the most, but the mids and highs are also so clear and crisp. I havent yet tried to change the atom modules as yet, I am sure this will make the XE6 even more great than that it already is.
The shells in the IEM I were crafted in the US (was crafted in China earlier, but as Trump wanted his MAGA force it had to be made in the US now)
This is definitely end game worthy!!!!
I’ve been using the Moondrop Chu 2 for around 5 months, and I’m really happy with them overall. The size is very good – small, lightweight, and comfortable for long sessions. They fit well in the ears and don’t feel bulky at all.
In terms of sound, they’re excellent for the price. Clear mids, detailed highs, and a balanced tuning that works great for vocals and instruments. They still feel solid and well-built even after months of daily use.
The only drawback is the bass – while it’s clean and controlled, it’s not very strong. If you’re looking for heavy bass, these might not fully satisfy you.
But if you want clarity, balance, and detail in a compact design, the Chu 2 are a fantastic choice.
Very good value for its price range,
Solid build, durable metal shells
Comfortable fit and decent ergonomics
Tuning flexibility thanks to interchangeable nozzles
Soundstage depth isn’t exceptional (though width / height are decent)
The black nozzle for brighter tuning is a bit aggressive.
This is my first IEM..so I'm not knowledgeable enough to decide if it's the best or not..but definitely a good buy..go for it guys..and don't forget to pair it up with a good dac....
I got these cables for my CHU II because I broke the stock cable.
For the following reasons I would say it's a solid recommendation for it's price.
The cables themselves are not as heavy as they might look and more importantly, they are not "stiff, ear hooks are also fairly comfortable.
Also, they don't particularly retain shapes and seem to be freer and tangle free.
The quality on the cables is good, it's been almost two weeks, and I haven't seen any quality issues come out.
The mic quality on calls is decent, very serviceable.
Don't expect upgrade cables to change the tonality of your IEMs.
These don't have a chin-slider, I would have loved to see that.
(THE COOLEST PART, they include a free hard case and tbf it's actually a good case better than some listed even for around 300INR out there)
Tuned like a blessing formy ears, Go for it
I use the moondrop free dsp mini with my hidizs mp145 planar iems and the response is amazing. Micro details are good mids are just right. The bass is tight. You'll love it.
After searching for around 7 days, I finally ordered these. I have received them just an hour ago. Will update the review in few days. Initial impressions are too good.

I own a mobile phone with only type, no headphone jack
I do like to comfort
But after reading everywhere that the dac and amp will change the listening experience, I decided to go ahead with the purchase
And afterIstarted using IEM with dan n amp , I cannot go back
This D07 has enough power to make thesound pleasant to my ears ,I doubt i will even considerbuying a more powerful amp
D07 is more than enough
Bought my very first IEM , and loving the kz castor pro ,bought 3.5mm jack version with a dac n amp
The experience is sublime

Audiocular packaging is premium always give a small pouch which can be very handy.Initially Right side was not working in my KZ Harman target Balanced version. Date Recd 7th Oct 2025! every thing is awesome Love Pritam for being Down to earth.I am going crazy at age 51 with this music world man
This thing is wild for the price. It's the ultimate budget champ if you're trying to get into good audio without breaking the bank. 😎
OK, sound check. It rocks a dual-chamber driver for a super balanced, chill vibe—easy listening, no fatigue. The mids and vocals are A+, straight up crystal clear and super detailed. The Type-C DSP bass is cleaner and mostly has a deep rumble. Not a bass-head set by default but so EQ if you want that boom-boom. The soundstage was way wider than expected. 😁
You can skip the standard plug for this one as the Type-C DSP is the MVP. It has a built-in DAC/Amp right in the cable, so skip the dongle and get high-res audio straight off your device. Plus, the Tanchjim app is really good and surprisingly more stable than others out in the market. Letting you customise the sound with a 5-band EQ and save presets. That level of control is insane for an IEM priced at this rage. 💪🏻
Comfort is 10/10. They're small, lightweight and look kinda minimalist in clear plastic. You get 6 pairs of ear tips and can customise as per your comfort and wear it all day. 😊
If you use a phone with a USB-C port and you wanna get good sound for cheap, just grab the Bunny. You won't regret it. ✌🏻
Allrounder iem
Got this today, and It's Awesome. Really recommend this IEM. I am a beginner and I find the whole experience user friendly. I has really great defauld sound . 100/10
