The Hisenior Mega5EST is a reference-quality IEM tuned with taste and subtlety. It doesn't shout for attention but rather invites you to listen deeper. If you're looking for an IEM that balances technical excellence with musical emotion, this one is a rare gem in the hybrid space. A true “listen for hours, forget the gear” experience.

This is the best MP3 player you can get for this price.

I'm new to the world of IEMs and this one was bought to try how it feels. Trust me, it won't disappoint you. Double the value compared to headphones of the same rate.

Budget king SMSL RAW MDA1. Very versatile music dac & headphone amp. Fully satisfied. Being an audiophile I was searching for best budget one got this from The audio store. Thanks for timely delivery. Nothing can match it at this price range period.

Works well with my Moto Edge 50 Pro. Other DAC's would have a lot of interference and static, the Moondrop Echo A has none. Audio is clear and the connector does not heat up at all. Battery life isn't impacted as well.
The build quality is excellent, cable is flexible and will fit in any iem carry case as well.

This is a great product with excellent sound quality. The bass is impressive and it's worth the money.

Beautiful and heavy duty balanced cable. Adds a weight to the music's bass i.e. tighter bass response.
Good product excellent sound well packed but delivery was delayed by two days.otherwise everything good.

Combo of cx31993 max97220 chip is more than sufficient to drive any iems

Using it with truthear crinicle zero red and works perfectly. Loving it

I’ve been thoroughly impressed with the SMSL RAW MDA-1, especially as someone who values Hi-Res audio and the transformative power of a great DAC+amplifier.
The build is solid, with a sleek, compact design that fits perfectly on my desk without taking up too much space. I love the variety of connectivity options—USB-C, coaxial, optical, and Bluetooth—making it easy to connect to my PC, gaming console, or even my phone. The Bluetooth feature is particularly handy for wireless listening when I want to move around without sacrificing sound quality.
One thing I’ve found is that it’s exceptionally well-suited for low to medium impedance headphones, delivering plenty of power and clarity. However, if you’re using high-impedance headphones, you might notice it struggles a bit with volume, so you may need an external amplifier for those. Also, while the 4.4mm headphone output is convenient, it’s not a true balanced design, which might be a letdown for audiophiles who prioritize that feature.
Given its price point, the SMSL RAW MDA-1 offers exceptional value, delivering high-end features and performance that punch above its weight class. It is particularly suitable for audiophiles and gamers seeking a high-quality desktop audio solution with both wired and wireless options. However, for those with high-impedance headphones or a preference for advanced sound-shaping features, it may fall short, potentially requiring supplementary equipment.

KZ Castor Harman Target with Improved Bass is just bliss for listening to music & watching movies.
