The Ausdom M04S Bluetooth headphones make a great first impression. From styling and design to performance 
and quality, all of the aspects come together to provide a great audio experience.

Once adjusted to your desired position, they feel quite secure. You can use the headphones while you go out for a run or workout, or pretty much do any activity that requires movement without the fear of the headphones moving of its own accord.
With a standard size and over-ear design along with plenty of cushioning both underneath the headband and the earpieces, you will find the headphones snug and comfortable. Both sides of the headphones are equipped with easy to use control buttons. While the right side features the play and pause functions, track selection and protected micro USB charging port, the left side has power and pairing button, volume controls and a high-quality inbuilt microphone to take calls.
It is a distinctive feature to have controls on either sides. It makes things simpler as the likelihood of pressing the wrong button is lessened. Furthermore, to make things even easier, the power and pairing button is not raised as much as the other buttons, so that you can tell the difference with a simple touch. Once you get the hang of it, the controls become pretty easy to use on a daily basis.
With a chic color contrast of red against black, the headphones make you stand out in crowds and add a nice pop of color while you enjoy your favorite music in style and comfort.

The headphones weigh only 0.60lbs which is pretty light to rest on your ears without being too aware of it. The dim
ensions are 6.00×7.00×1.50 inches.
Materials and Comfort
The headphones are made from a combination of good quality synthetic leather and plastic. The ear cups have artificial protein leather earmuffs for a human skin like texture, along with a matte black finish with a fine turtle shell detail on its outer edges along with a fun pop of red color. The headphones pitch and swivel for your comfort, and as mentioned above, there’s plenty of room for vertical adjustment. The 180 degree rotated ear cups offer easy storage and adjustability.
These headphones definitely take the cake when it comes to user comfort. They are one of the best headphones in the market in terms of comfort. The headband and ear pads are well-padded for cushioning and a soft and supple touch. You can wear them for long hours without feeling any discomfort. The material itself is breathable to some extent, so that there’s varied degrees of moisture control. The ear pads, along with its plush cushioning, provide a complete seal around the ears. This prevents audio leakage and enhances sound isolation while preventing any outside nuisance to disturb audio quality. It is recommended to take the headphones off for a while from time to time if the ears get warm in hot weather.
Sound Performance
No amount of comfort or high quality built can save a headphone that doesn’t deliver sound audio quality. This is where these headphones shine! You’ll be impressed with the audio quality of these headphones with notable features such as ‘high sensitivity’ and ‘deep bass’, thanks to the 40mm drivers and advanced chip that deliver HD sound optimized power bass.

If you are a bass-head, you will enjoy the audio performance of these headphones immensely. For the given price, these Bluetooth headphones perform way better than one might expect. Compared to the rest of the headphones in M series of Ausdom, M04S has more emphasis on bass with a soft impact that delivers rich audio with a hint of bloom. The midrange can
feel a little underwhelming as the emphasis is on bass, but it still remains laidback and smooth, with a rolled off treble.
Another great thing is that the volume is really loud – so that it can always be adjusted according to your preference. The audio is distortion free at highest level, and the delivery remains clear and clean thanks to sound isolation.
