Lypertek SoundFree S20 Review

Lypertek SoundFree S20

Today we look at the $69 USD Lypertek SoundFree S20. It is available on both the UK & US Amazon.


Disclaimer: Lypertek sent us the IEM for this review via HifiHeadphones in the UK, free of charge. I only covered the import taxes and fees. All thoughts and experiences with the product are naturally my own. You can find out more about Lypertek here.


Many of you are already acquainted with Lypertek because of their brilliant IEM, TEVI. It was a huge blast around a year ago and Lypertek got many praises for TEVI’s sound quality & battery life. As Headfonia, we also listed TEVI on our recommendation list!

Let’s talk about Lypertek for a bit. Lypertek is a Chinese audio equipment manufacturer that mainly focuses on true wireless earphones. Did you know that their first releases came under the brand Oriveti in 2015? They are quite active in many regions. TEVI’s huge popularity of course increased the demand towards a “something new” from Lypertek. That day has finally come. Shall we see what they achieved this time?

  • 3x Pairs of Double Flange Ear Tips S/M/L
  • USB-C Cable

Packaging & Design

The Lypertek SoundFree S20 comes in a plain white box. A transparent box welcomes you as soon as you slide the top cover up. I noticed how small the carrying case was as soon as I opened the box. Specifications and technical data are listed on the back side of the cover and package contents are listed on the side. Honestly the outside cover is a bit blunt for my taste, I’d much prefer if they had continued the packaging design of the TEVI. However, we pay for performance, this is especially true when we’re buying budget-oriented gear.

The S20, as you can see above, comes with a limited variety of accessories however, I wished for double flanges before on the TEVI review, now they are included but foams are gone. I’d say it’s a nice trade-off for me but it may not be this case for other audiophiles. Let’s talk about the product design for a bit. The case is small and made of a semi-rough but lightweight material. The material feels different and honestly I like different. It definitely does not feel cheap. The hinges seem durable. There are 4 LEDs on the front of the case to let you know about the battery status. Magnets work great. The earphones sit safely inside the cradle. The charging port is USB-C and it is located under the case. The case also supports wireless charging and that is really nice for a $69 USD product.  Both the earphones and the case are lightweight. I can also say that the case and earphones are 100% fingerprint-proof.

The earphones weigh about 5 grams each. There is a button on the side of the earphone and I really like this button placement because you actually can click it without breaking the seal. The earphone design is somewhat similar to the case, especially the faceplate. The shape is designed with ergonomics in mind. It is not as big as its bigger brother, TEVI. The S20 is around %30 smaller. The long nozzle helps with the fit and the Lypertek logo on the faceplate looks very cool. The LEDs are not bleeding through the faceplate like some of the budget TWS earphones and they are not absurdly bright. Simplicity is the essence here. I like the design and I believe they are quite durable. Thanks to the IPX5 waterproof rating, you enjoy these while running or doing sports.

Comfort & Isolation

The Lypertek SoundFree S20’s nozzle is long and its housing is compact. The inner side of the shell is shaped in a way that helps it stay comfortably on your ear’s concha during extended listening sessions. The passive sound isolation is quite nice, it blocks out my computer fan which is about 35dB. The fit is good and secure so I can use it while running as well. 

Stability & Features

The SoundFree S20 has a lot of features for a budget IEM. Let’s start with the battery. Lypertek’s TWS lineup is praised for their battery life and SoundFree S20 is no different. It offers 8h of playback and extra 40h of juice via the case. I can’t really wrap my head around how they manage to fit a big battery inside such a compact case but it is really awesome that they achieved it. On a side note you’d think that a battery this big would increase the weight of the case yes? Actually no, it somehow does not. Great job Lypertek, much obliged. Aside from awesome battery life, the TWS comes with fast-charging capability and just 15 minutes of charge can provide you 2 hours of playback. auto pairing and auto on/off. It automatically goes into battery preservation mode when it is not being actively used. 

It also has an ambient sound mode. It is designed to make the urban life easier and lets you talk to people without removing your earphones. It can be activated by clicking the multi-purpose button 3 times consecutively. Since we are talking about the button, let me just go ahead and tell you all about it. First of all, I already stated that the placement is really good. If you follow my reviews you know that I don’t really like touch-sensitive earphones because it is so easy to misclick or random stop songs while adjusting the fit. I don’t know how many times I declined incoming calls and so on.
