Enjoy an open-back-like sound with the comfort of an IEM with the 64Audio Duo. This IEM comes with a single dynamic & balanced armature driver. Packed with their patented tia, Wave Sync and Apex Core technologies, it delivers lifelike audio like none other.
It’s an IEM, It’s a Headphone, It’s the Duo!
Immerse yourself in every auditory delight with the 64Audio Duo. The relaxed tonality ensures a non-analytical treble while retaining its airy presentation and sizzling performance. An open-air design lets you feel connected to your surroundings while creating an unobstructed soundstage with impactful centre imaging (unlike many other open-back headphones) with no loss of bass for deep and rich low frequencies with plenty of sub-bass.
Two Times the Fun
Experience a timeless design that’s inspired by open-back over-ear headphones. The Duo’s faceplate allows the free flow of air to the drivers while protecting its shell. The premium cable consists of silver-plated OCC Copper wires for smooth audio transmission. This complex design is a major step ahead in developing 64Audio’s finest IEMs.
tia Makes it Better
The Duo’s patented Tubeless In-Ear Audio (tia) system reduces unwanted resonance and distortion for a transparent and lifelike sound. This is achieved by allowing the 9mm Dynamic Driver and tia High Balanced Armature Driver to radiate freely in the single large tia bore with no obstructions in front of the drivers. It features special acoustic chambers instead of tubes that constrict the sound of the drivers.
Wave Sync & Apex Core Technologies
To ensure coherence between the high crossover point of the two drivers, an industry-first Wave Sync was developed. It features a type of ‘all-pass filter for the crossover to correct the time without having to change the physical distance between the drivers. The Air Pressure Exchange (Apex) Core allows seamless airflow to the shell which uses a perforated grill on the faceplate to prevent the obstruction of air for effortless reproduction of music and minimal physical fatigue.

Sony does not disappoint with the NW-A306. I like the customization possibilities and the android interface.
The shell is big bit somehow very comfortable fo extended use. The sound signature is about what I expected soo no complaints there. The only thing is I'm not a big fan of l connectors but that's a minor gripe.
This is my first IEM and my mind is blown by the audio quality of it and also the premium feel and built quality of the IEM which is made by Zr ceramic. It not only looks and feels good but also the clarity, passive noise cancellation, and comfort are good. Definitely a 10/10 and would suggest the people to buy it. The gift packaging it came into was also very thoughtful from the side of 'The audio store' people and was impressed by it.
Great experience with this earphone, thanks the audio store. Thank you for your quick response to a small problem.
Excellent layering delivered with kinetic bass on a wide sound stage. 👌.
This is strictly for metal and rock heads...the force and speed of attack is phenomenal on these...this is coming from a guy who has S12 , EA 500 & Sundara which are well known for speed and resolution themselves... suprisingly the treble is not harsh at all and sibilance is completely absent (major pain point of S12)..never expected such a sound signature from a non planar set but that's the magic of this hobby ..you get sleeper hits like SR 5 from time to time 😀...Soundstage and separation is adequate..not out of head...you will not get time to focus on all that anyway as the cohesive and authoritative sound will take your breath away before that 😜
Thanks Pritam Ji for bringing this to India and listening patiently to your customer's requirement and suggesting suitably.
Note : the photos in the website are of the old packaging...it has improved much now and Sound Rhyme provides a metal and a leather case along with foam tips now..check the pics of the package i received. I swapped out the stock 3.5 cable with a balanced fiio 4.4 one ..but the stock cable seems to be of high quality as well.
A good connector for 2.5mm to 4.4 mm jack . I prefered it due to expensive cable I have purchased for 2.5 mm connection which is useless in 4.4 output now I can use it once again.
The Krila is an excellent IEM. The sound has a mild v-shaped tuning which renders a solid punch to the bass and sparkle to the highs. The bass is tight and goes very deep but is not overwhelming. I find it to have a slight mid bass bleed but not to the extent of drowning the mids. Vocals sound quite lively but is slightly recessed owing to its v-shaped tuning. To my ears, the treble is sparkly with lovely instrument separation. It also gives a good sense of air and space. The soundstage may not be as wide or deep as other more expensive iems but is very much acceptable and even better than some others at this price point. The lower treble has a slight peak which may sound a bit piercing at high volumes, but is otherwise very detailed. The result is a fairly balanced signature with a slight emphasis at the frequency extremes and sounds very lively and enjoyable. Add to this the stellar build quality with beautifully crafted metal shells and I feel we really have a winner here for less than 2k. I am now tempted to collect almost all the other KZs :) The memory foam ear tips included in the package are excellent too. A better quality cable with chin clip and a carrying pouch would have been great.
This was suggested to me for my preference, i was very sceptical to see how it would actually be, the moment i put it on it was very special and a bliss, extremely comfortable, extremely non fatiguing, you can wear it for 8-10 hours straight and forget you are wearing it,
also has bass for bassy songs, clear mids and vocals, amazing treble, i dont think there can be a better IEM as this has no downsides!
Strangely, it works for music play but does not work for call audio. Not satisfied with the product.
7HZ 71 Portable USB DAC is good one for music lovers. With a good pair of iems you can feel the difference.
Sound is good delivery is good earphone new condition thanks audio store
For the cost the cable looks good quality.... had problems with the one who came with the dac. Extremely easily and without a hint of fractures rotting in any direction. The connectors sit tightly.
It came quite fast.
For context, I own the Fiio FH3, Truthear Zero, Simgot EW200 and now this. All the above had slightly offensive upper mids. While I actually like that to an extent, it sometimes got too much that I had to reduce the volume whenever I listened at high volumes. The EM6L while warm at lower volumes, it starts getting brighter at higher volumes, but mind you it's just the right amount of it imo. And it's less offensive than the rest.
While the Fiio FH3 has a much better build and a better punch to it, the EM6L has better technicalities. The Soundstage between the two are similar when connected with a 4.4mm output, the EM6L has better layering and depth perception that it helps if you are gaming.
I primarily game, and am a casual music listener, and in that aspect, I'd rate these above all the other IEMs I mentioned. But the Fiio FH3s come close, and may not be a bad option with its better build and punch. If you're into Hip Hop, the FH3s would be better, but the EM6L is a better all rounder.
Construction is solid, Connectivity is easy, easy to operate, there is no audio delay, it gives output to all the ports so if you have two set of speakers you can run them parallely. The only con of this device is it decodes only upto PCM 16Bit/48kHz over USB.
