TRN BT20 Pro (2-pin QDC) as described in the advertisement. Excellent packaging, materials, construction, and overall quality. Bluetooth performance according to specification, range of 10 m. Tested with various IEM earphones (KZ D-Fi, KZ PRX, Moondrop CHU II, SGOR Adonis, TRN Conch), all with excellent results. The battery charge indicator of the headphones remained at the same level even after playing music for 1 hour. The case took 1 and a half hours to charge from 75% to 100% (10W charger), but the size is too large to carry in a pocket, ideal for a backpack. Very satisfied overall.
It was well-packaged with no defects, and the shipping was fast; I'm glad I made the purchase. The product's packaging is also nice, and I bought a set that tested well with no issues. The main case is quite large and can even store earphones, and the sound quality is quite loud for wireless devices, even better than wired ones. It doesn't cut out when moving to another room. The volume is a bit low even at maximum, so I don't think it's suitable for multi-player use, so I'll use a DAC! The sound quality isn't bad, leaning towards low-mid tones. I think it's a very good product for outdoor use with wireless connectivity. I'm glad I made the purchase, thank you to the seller!
I received the product as ordered. All three ear hooks arrived in good condition. At 16 ohms, the CCZ CZ10 (1DD+4BA) has a volume that, when connected to a laptop and enhanced with the Nahimic program, is just right so that the earphone sound does not crack at the maximum volume in Windows 11. The volume is the same as above on the TRN Whale Shark (3DD + flat plate) with the same 16 ohm impedance. For products with a resistance of 16 ohms or higher, the volume may be a bit lacking. When connected to a laptop, the phone's Bluetooth output is about 50% higher than that of the laptop, so it's 'sufficient' when connected to a phone (Galaxy S21). If you use it on a phone, a product with about 30 ohms seems suitable. To drive earphones with higher resistance, purchase the BT30 Pro with an amplifier. I received the product and am currently charging the case, but if there is space inside to insert a wireless charging coil by disassembling the charging cradle in the future, I will try to modify it by inserting the wireless charging coil. Haha. Without checking the interior space, I already ordered a 5W wireless charging receiver coil from Ali's Tianyang Corner. Please... I hope there is an internal space to accommodate the wireless charging receiver coil.
I am using it with kz ZSN (2pin (0.75mm)). There is no white noise and the sound quality is not bad. This is quite convenient ♫ Since the main unit is large, the case is also large, so I only use it inside the house. Thank you for the good product!
They arrived in perfect condition, as a first impression they feel very comfortable, even with glasses. It has a quite clear and faithful sound with music from Spotify, I hope it will be even better with Tidal. When the music is paused, nothing plays, not even Bluetooth interference or anything. When connecting them with my Zero:2, I only need 20% volume for them to sound good in a quiet space. The buttons on the modules sound a bit loud but it's not bothersome. The module box feels a bit "empty" but it feels very well constructed and its opening and closing mechanism feels very sturdy. In calls it sounds horrible being honest (like any Bluetooth thing in a call), it takes a bit to switch "mode" so to speak, but when it switches to use the mic, the sound pauses and then it goes back to this mode using the mic. In the same way, just with my first impressions, I am very satisfied with the product.
Good power, I barely noticed any distortion in the sound with the TRN Conch and the Tin HiFi T2, satisfactory volume. Good battery, well-built case despite the large size, earhook is quite compact and comfortable, low connection noise and a pleasant tone.
I bought this device for my boyfriend to sports.but remember—this device itself is water-resistant, but the connected iems never are. We spent many hours choosing the right iems from my rather large collection(over 30 pairs,i guess) that he would enjoy. To my surprise,the adapter handled planar iems quite well despite their demanding nature,but in the end we decided to go with ms1 iems to save the device’s battery life. The sound is clean and not distorted—it performs roughly on the level of a mid-budget dongle, which is perfectly fine since the device is used with an apple's device that doesn’t support high-resolution bluetooth codecs anyway. We settled on a pair of inexpensive dynamic iems—they have a fairly large shell, but the adapter, iems and eartips all fit nicely into the charging case. After a week of use,we still haven’t had to recharge the case once. The device ended up being used much more often than expected—the apple user suddenly got very curious about good sound quality!
Coming from some TRN BT20XS, there isn't much difference in terms of sound quality. The bass tends to distort quite a bit if you increase the bass in the graphic equalizer on your phone. However, the mid and high frequencies are well balanced, making each element that makes up the music you're listening to noticeable. Another improvement it has are the earhooks, they have a different design from the BT20XS, allowing it to adapt even to the smallest headphones of the brand, the TA1 Max, well done there. As for battery life and connectivity, it delivers what it promises, 13 hours of continuous use and better connection stability. Despite the only drawback of the audio quality (especially for the bass), I am satisfied with the purchase :]
I really liked the module, I just didn't like the size of the case; it's too big, and the battery percentage could have been displayed digitally instead of using four dots. At least on my phone, the battery percentage of the earphones appears digitally. The HD sound mode is excellent, just like the KZ's.
It works perfectly in my zero 2 iems , really good sound quality and actually quite low latency, only had problems connecting to my switch 1 where it sounds horrible, but tested on switch 2 and it works así intended, probably because of bluetooth version
I ordered the full set version, but the package on the main unit was labeled as 2pin, and there were small bags labeled MMCX and QDC at the bottom of the bag. Even when wearing glasses, it's not a problem; small wireless earphones are indeed convenient. The sound quality isn't bad, but occasionally there is a slight noise. I'm not sure about the durability, but I highly recommend it.
TRN BT20 Pro easily converts wired earphones to wireless! Good sound quality, stable connection, 50 hours of playback. The case is a bit large but extremely convenient to use.
Ok, everything is fine, I recommend the seller. The sound quality on the PC is practically equivalent to wired headphones and it has an amazing battery life. You might need to use a bit of force to close it with a large IEM.
The strength lies in being able to go wireless with iems at this price point. Sound quality depends on the wired cable used, and while the sparkle in the highs, depth in the lows, and overall spatial presence diminish somewhat, it feels perfectly adequate if you accept it as a solution for on-the-go use. If you prioritize sound quality even slightly, i recommend purchasing higher-end ear hooks. Considering practicality, cost performance, and my own usage, i'm personally satisfied.
I bought this because I was able to easily convert my wired earphones into wireless ones. While many models have slightly lower sound quality than wired ones, I've used it for about two days and haven't experienced any ear fatigue. It was less than 2000 yen during the anniversary sale, so I think it was a good purchase. The case is indeed large, probably for home use. I don't know about durability yet, but the battery life seems better than I expected.
