About TRN

TRN is a high-fidelity headphone company that focuses on bass. Most TRN products emphasize excitement in the low-frequency region. They hope to create multifunctional headphones that can effectively navigate rock, pop, symphony, and large weaving styles. TRN's latest product, TRN BT20xs, is a true wireless Bluetooth headphone module.

40 hours non-stop music playback

We all know that for Bluetooth earphones, battery capacity is one of the important criteria for evaluating their performance. If you use TB20xs, you don't have to worry about battery level issues at all. It can play music continuously for 40 hours. And it only weighs 8 grams, so your ears won't feel tired either.

High Quality bluetooth chip bluetooth 5.3 fast connection

Compared to Bluetooth 5.2, Bluetooth 5.3 has an effective coverage range of 15 meters. At the same time, it only takes 0 seconds to complete the switching action between the master and slave headphones. The latency of Bluetooth 5.2 is about 300 ms, while the Bluetooth 5.3 used in TB20xs reduces the latency to about 100 ms. In summary, this update to Bluetooth has greatly improved both the user experience and feedback on actual data.

Easy to have AAC/SBC wireless HD high fidelity experience

TB20xs has multiple headphone pin jacks, which is very convenient for IEMs. It enables you to have AAC/SBC wireless HD hi-fi experience very easily. You can easily turn a wired IEMs into a wireless HD hi-fi Bluetooth headset at any time and any place. It comes right out of your pocket when you need it and is ready to go right away.

With multiple touch functions and waterproof and sweatproof function

TB20xs has convenient touch buttons. It can complete five touch functions: "power on/off", "previous/next track", "answer/send a call", "enter pairing mode", "play/pause", making it very easy to operate and use. The soft material makes it very comfortable to wear, and it is also waterproof and sweat resistant.

Another satisfied customer!

Great product, working without any hassle at all. Battery time is great. And the sound quality (with ZS 10 Pro) better than expected! For the low price (less than 20 Bucks) a real steal!

Rob Ashbourne
Great product (0.78mm 2-pin)

Converts my IEM into viable Bluetooth option. Bluetooth 5.3 is excellent, I have no connectivity issues when using them. No audible issues, this adapter provides more than enough power to drive my IEM's. The customer service updates on my purchase was also very good, I was able to track my parcel from dispatch to delivery. I will be using Linsoul for future Audio purchases.

Value for money

Unfortunately there is no volume on the unit so you are maxed out with the source volume. Other than that it's a decent piece that gets the job done

Sophanna Ven
Good for the price

good for turning your iems into wireless

Picked this up because of the low price, case has a nice rubbery feel to it and zips shut with even my largest IEMs. Connection range is solid can walk to the other side of my house with no drop outs, main flaw is only having SBC/AAC which is to be expected for the price, depending on song bluetooth compression can be pretty noticable, minimal noise floor still noticable on more sensitive IEMs but not annoying unlike other cheap bluetooth stuff I've had and inaudible when music is playing.
