Adequate purchase, best sound you will hear.
Probably double volume than TWS.
Looks seriously different than other headphones I have used till now, you look different than rest of the crowd(in the gym especially), that makes you feel special 😊☺️

Must go for it Bluetooth & DAC AMP

- Audiocular SPARK DAC is one of the best looking dongle DAC I can find also the audio quality it throws it's just supirior to any normal phone or pc DAC.
-Well there is lot of DAC with same configuration but on higher price this one feels premium and it's just under 1000 bucks so I don't think so you need anything else as a beginner or anywhere for regular use it's best of best.

- I was really confused between salnotes zero 2 and moondrops chu 2. After lot of thinking and chatgpt decided to go for Chu 2 well my initial experience was not good because I was using realme airbuds 5 pro which is a great wireless earphone dual drivers but mostly bass heavy so chu 2 bass felt lacking at start but it's just initial expression once I got comfortable with it is blown my mind cause it's really well balanced you can hear good amount of sound seperation bass is good and don't leak into the other instrument details or vocals.
- I purchased it with audiocular spark DAC
And honestly it's deadly combo it improves so much sound quality and bass and on top of that the fit of chu 2 and cable is really good and with this DAC it feels aesthetically pleasing as well.

Awesome headset
It was such a great MP3 player for the price. There was enough space as 32 GB memory card was provided. Also, we can read e-books in text format. It's so convenient during travel. FM radio is also present. Lot's of features in that small gadget ❤️.

The ear tips are good for starters and do have variety so I'm sure you'll find something comfortable. It can revive your interest in your old IEM's don't expect much as they are just there to deliver comfort to your ears.
New experience with the iem
Amazing sound very addictive ear phones might have been perfect if they came with c type connector
Build quality and audio clarity

Kudos to makers/seller for making it to available.
Purest form of audio hearing experience with this cable.
Happy with the purchase.

The build quality of this cable is top-notch. I’m using it with my HD560S connected to a laptop via Apple Music, and the difference is noticeable. The bass feels tighter and especially welcome improvement for openback headphones and there's a clear boost in instrument separation and overall clarity. Upgrading to a balanced connection has definitely proven to be a worth while decision.

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.
