KZ S1 vs Edifier TWS1 – Design & Appearance Comparison

Before we talk about the way these two pairs of wireless headphones work, let’s talk a bit about the most notable thing, their design. At first glance, we can see that these two are very similar since both have the very useful and popular full in-ear design, which gives them the opportunity to position themselves in a great way inside the ear, avoiding so there are so many problems when the user is on the move.

Likewise, all these wireless headphones are ergonomic and very light, in addition to being adaptable to any size of the ear since they have sport rubbers of three different dimensions. It is worth noting that they are not resistant to scratches and bumps, so you have to be very careful with them. Also, the Edifier TWS1 has the much-needed IPX5 certification, and while this type of certification makes the devices waterproof, it is not that recommended to fully submerge them in water.  On the other hand, KZ S1’s company has not said a word about the IPX certification these earbuds have.

Having said that, and this being one of the best characteristics that both earbuds have in common, is that they both have touch panels, which although they are not capable of carrying out complicated actions, do work with the most basic and important controls.

KZ S1 vs Edifier TWS1 – Comfort & Wearing Experience Comparison

Concerning the comfort that these headphones offer, ultimately they have many points in their favor. Since they are made of plastic, the earbuds are extremely light, in addition to having three silicone ear tips (S, M, and L) which are suitable for almost every ear size. Likewise, and due to their comfort and the certifications they have, they can be used not only as common headphones, but they can also be used when exercising since they cling very closely to the ear, which is always a big plus point.

About wearing, they can be used for a long time as long as the appropriate size of ear tips is being used, although, and like any other headset made of plastic, it can be a bit annoying for some users.

KZ S1 vs Edifier TWS1 – Charging Case Comparison

Now, and talking about the charging case of these earbuds, the truth is that there is not much difference between them. Both cases have a magnetic closure mechanism, which can assure us that it will not open with any movement we make, thus keeping the headphones safe. All are charged through a micro-USB port, which is charged thanks to a USB Type-C cable provided by the same company.

On the other hand, the charging case of the KZ S1 has a battery with a capacity of 300mAh, while the charging case of the Edifier TWS1 has a battery with a capacity of 500mAh.

KZ S1 vs Edifier TWS1 – Hardware & Performance Comparison

When it comes to hardware, many people would think that some high-end chip made by some popular company is inside these headphones, and that’s the case for one of these two earbuds. The pair of headphones that work together with a chip made by Qualcomm is the Edifier TWS1, and it is that it works hand in hand with the Qualcomm QCC3020 chip, which has already been present in other wireless devices. On the other hand, in relation to the KZ S1, there is no knowledge about the chip that it has inside.

With that being said, one of the highlights of these products is the master switch added to each earbud. This means that either of the earbuds will serve as the main earbud and will carry the functions of the main earbud (play, pause, call, forward, etc.). This is a useful approach because if you lost an earbud or one of the earbuds gets faulty, one can easily use another earbud as a mono earphone with the same functionality.

KZ S1 vs Edifier TWS1 – Sound Quality Comparison

Now moving to the sound quality, the reality is that you can’t expect professional audio; Remember that when buying any model of True Wireless headphones, you are dispensing with audio quality to gain comfort. In this sense, the Edifier TWS1 has an 8mm dynamic driver, while the KZ S1 has a 1DD + BA combo (One Dynamic Driver + Balanced Armature). The difference between BA and dynamic drivers is that BA does not displace air to produce sound, having a lack of bass as a result, although the single dynamic driver that it has improves this aspect a bit.

Although they do not give the best sound on the market, to get a better listening, you can turn the volume up to its highest capacity, because they also have the ability to provide a really good bass quality.

KZ S1 has:

  • Better performance in the treble frequency than Edifier TWS1
  • Better detailed sounds than Edifier TWS1

Edifier TWS1 has:

  • Better clarity than KZ S1
  • Better bass than KZ S1
  • Better controlled bass than KZ S1

Having said that, by being placed correctly on the ear, these two earbuds are capable of keeping external noises moderately opaque, and that is that although external sounds could still be heard a little, everything can be solved by setting the volume of what it is being listened to 100%, which is performing in a good way.

KZ S1 vs Edifier TWS1 – Talking / Call Experience Comparison

About the experience in calls, there’s no microphone difference in both earphones. They have the same mic. Also, the call quality is just average, nothing special. They can be easily used when talking on the phone in any closed space, although the problem comes when they are used in open spaces with noise; the audio and microphone quality drop immediately, and if there is a lot of noise, it will be almost impossible to have a conversation that can be understood.

KZ S1 vs Edifier TWS1 – Connectivity Comparison

Due to the use of Bluetooth 5.0, the connectivity of these two headphones to other devices is of high quality, in addition to is capable of greater stability, battery optimization, and have a faster connection speed. The Edifier TWS1 has a range of 10 to 15 meters of connectivity while the KZ S1 has a range of an amazing 20 meters and, on top of that, we found that they can be used separately and linked in the same way. Also, they automatically connect after removing them from the box after being paired with another device.
