The Sudio E2 package meets the price standard.
There is no shortage of accessories. The package contains the following:
- Sudio E2
- Charging case
- USB Type-C cable
- Eartips (5 sizes)
The build quality of the Sudio E2 is well worth the price. The matte-textured case feels smooth, gentle, and comfortable in the hand.
The fit is good.
I tested it by connecting it to a Cayin N6II/E02 with AAC.
I don't know because I haven't been in crowds, but it is stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The sound is momentarily interrupted when there is a barrier between us, but then it returns and we can hear the music consistently.
There may be a small amount of white noise, but most people probably won't notice it.

REW Frequency ResponseSound quality
Sound quality description
The following review was tested on a FiiO M15 with an SBC connection.
The sound signature of the Sudio E2 is V-shaped with an emphasis on depth. By default, the sound has a wide sense of depth in the midrange, but it tends to sound cramped and not very audiophile-friendly due to poor transparency and a sense of ceiling in the high frequency range. However, when the spatial audio mode is turned on, the sound field sounds extended, providing a highly immersive experience. For the actual effect of the Spatial Audio Mode, please refer to this article on Recording Signatures.

Sound quality general comment
Sudio E2's spatial audio mode is very interesting because it makes music sound three-dimensional. However, it seems to add reverberation and other elements to the music, and some songs may sound oddly unnatural in texture or have a distorted sound image.
And the E2 without spatial audio mode is below mediocre sound quality for its price range, and I personally do not recommend it at all. By standard, the Sudio T2 gives a much more wonderfully balanced and resolved sound.
Sound quality features
- Sound with a sense of depth
- Low frequency range full of realism
- High sense of definition
- Highly immersive spatial audio mode
- Sounds cramped when spatial audio mode is off
- Resolution is not good
- Muddy and dull sounding midrange
- Spatial audio mode works unnaturally with some songs
The main attraction of Sudio E2 is its unique spatial audio mode. It has the potential to provide a more immersive sound experience. ANC performance is also quite decent for its price range, and it has a full range of features, including support for wireless charging. Most importantly, the design is stylish and comfortable to the touch.
However, if the spatial audio features do not appeal to you, you may recall that the Sudio T2 is cheaper and offers better quality sound and better battery performance.
