I bought one ZA3 and I felt both happy and sad - I had avoided class D like the plague till date for obvious reasons and I felt like a fool for the same. I was impressed with the clarity straight out of the box and ended up ordering one more box to use each as a mini lock for my system. The low end is good and quite defined, the upper registers definitely are good, but could be better. May try and get a couple of sparkos op amps and see if it improves it. For the money paid for biamping, it definitely sounds like a great option in lieu of AB class amps. It costs just 50% of entry level amps, but definitely offer more power and quality as compared to those amps. The QC control and build quality seems solid. And the foot print it occupies is rather small. I can look at this amps performance and say confidently that cheaper non hypex class D is here now and it’s here to stay.

Let customers speak for us
from 4267 reviewsI bought this TangZu Wan'er S.G IEM With Mic for my music listening, really they are awesome, excellent sound quality. Full satisfied with the experience. Thank you audio store.
Resend the option
I loved the crispness in the audio which I have never experienced in any other earphones. These are truly amazing and worth every penny
Value for money, worth the investment.
I was so much sceptical about this IEM and after purchasing as well I was shocked to see it doesn't come with any nice packaging, casing was not looking very premium etc. I talked to Pritam and he clarified all my confusions. And the sound signature, man 🤌🏻 seriously I don't use my all other IEMs as much as this now. It's really rich, exciting and something special. Thank you so much 🙏🏻
When I received this product I genuinely say that the packaging was pretty well (good) and the sound quality is awesome with the pc, and it's weight, fits in my ear.
Allover the product was good.
Audiocular D07 DAC, and I’m thrilled with the quality and performance it delivers. Right out of the box, it was clear this device is made with premium materials, giving it a solid, durable feel. Setting it up was a breeze, and it worked flawlessly with my system.
The sound quality is impressive crisp, clear, and well-balanced across all ranges. The D07 DAC really brings out the depth and detail in my music, revealing nuances that I hadn’t noticed before. It handles a wide variety of audio formats seamlessly, making it perfect for high-resolution audio streaming or playing lossless files.
Overall, the Audiocular D07 is an outstanding DAC, delivering high-quality audio at a reasonable price. It’s a great choice for anyone looking to elevate their listening experience
Great sound quality for the price
Sounds very enjoyable and open and also has good imaging and instrument separation and definition to the various components of music is great. More clarity than HD 650 and also warmer but crispy sounding. I have the ifi zen stack but I like it more with just the zen dac v2 balanced output. Great headphone under 30k if you like warm sound with vocal intimacy and details of instruments.
Convenient carry case, easy to travel with.
Excellent sound quality and improved bass!
My good friend Pritam recommended this speaker to me. I went to his store and started listening to it and before I knew it, 3 hours had passed, and it was 9:30 pm! I bought it on the spot, had dinner, came home, and listened to it till 1 am.
During and after my listening session I realized a few things that made me fall in love with this speaker and it’s these things that compel me to write this review. I believe more people should know how beautiful a product this is. First and most important I like is its sound which I think is very natural and balanced. All the frequencies, especially the lower ones, come across extremely naturally with perfect weight and emotion. Personally, I’d give male vocals a slight edge over female vocals (I’m nitpicking). Second is its feature set which is very good with Bluetooth, Airplay, USB in, and Aux in being available. I am using this over Airplay, and it works oh so nicely! The fact that it allows me to listen to my music uninterrupted is so refreshingly good as it is something that was not possible for me with the Bluetooth speakers I was using earlier (too many interruptions with calls, notifications, alerts). Third, its battery life is very strong, I’d say 8-10 hours easy. Given its sound quality, size, and volume which is sufficient for my 20 x 12 hall, I think this is an excellent feat. Fourth are its looks. Its theme for me would be less is more, simple, and elegant. It has a very tasteful design that reeks of class!
And now I come to an aspect that I just realized how much I missed. I am an IEM collector and have numerous IEMs. I am used to high-quality sound and thus never really enjoyed speakers. I used to have my IEMS in my ears for long hours. The downside to this was that I could not talk to anyone. With this Edifier speaker, I now do not miss my IEMs. I have the high-quality sound that I’m used to (even at low volumes) and can carry on conversations with people around me. Even at Pritam’s store where I was testing this speaker for 3+ hours, it felt so good to chill and listen to good quality music and still be able to talk at the same time. It has a very pleasant sound that I just want to keep listening to.
I am 1,000% satisfied with my purchase.
Perfect match for my earbuds, staying put nicely.
I want to thank The audio store whole heartedly for this wonderful buying experience.
Package came completely sealed with a gift pack and delivery was super fast. Great work 👏🏼 I could feel the warmth shown by this store for audiophile community.
My first IEM. I did a lot of research and ended up buying this studio edition.
Crystal Clean sounding
Crisp Vocals and instruments
Nice details - which I prefer the most
Soundstage is good which really surprised me.
Comfortable fit
A slight thump is missing. May be I can slightly increased the bass using EQ.
Well I am in love with this tanqzu waner studio which perfectly suits my type of listening.
Laid back prolonged comfortable listening with all the details and clean sounding.
I have paired it with D07 Which I bought from other store as it was not in stock here.
Don't pair this with D07. This D07 DAC has background hissing noise. Try someother dac.
Loved the package and the IEM too..!
Tuning is great and I am yet to use it intensively but initial experience was nothing short of amazing..!!!
