Review on 🎧 Linsoul TIN HiFi P1: Premium Planar-Diaphragm In-Ear Earphones with Detachable MMCX Cable - A Must-Have for Audiophiles and Musicians by John Benjamin

. Please note that this is my opinion and that everyone has different ears and different brain wiring (yes, there is such a thing as psychoacoustics). So your mileage may vary. They have planar magnetic drivers. If you don't know what that means, read about headphone drivers. They have a low impedance of 20 ohms and a decent sensitivity of 96 ± 3dB. However, they behave like full-size planar monitors and typically require more power than the numbers indicate (see Audeze LCD-X). What does that mean? The more current you draw from your amplifier, the more responsive the driver will be. Because phones that still have a headphone jack don't have much power, P1s sound very weak. Therefore, you must use them with AMP. I tried this with: Dell XPS 13 laptop headphone jack: barely manages it properly. It's got plenty of power, but the sound straight out of laptops generally sucks. With Tin HiFi P1 you really realize how annoying it is. FIIO BTR5: Great Bluetooth/DAC/Amp for listening on the go. However, with an unbalanced 3.5mm output (80mW, 32Ω, 1.6V RMS), the BTR5 struggles to make the P1 sound good. Overclocked to 60 (maximum) not reached. So I connected a $20 balanced MMCX cable, which you can find here at Revain, to the P1 to connect the BTR5's 2.5mm balanced output (240mW, 32 ohms, 2.8 V RMS) and now let's talk. At 40 (66% volume) the P1 sounds divine, with excellent detail, decent bass and a good soundstage (regardless of what Zeos says :). Proof of this is that I've been listening to Tidal playlists from my phone over BT (LDAC codec) for over three hours straight and just dissolved into all those details and spaces. Dragonfly Red: There is no balanced output here, but the Red delivers 2.1V RMS power. and that's enough to drive the P1 well. But I don't like red. I'm not sure if it's distortion or just its sound signature. Hiby R5 DAP: has enough power to drive very well. It was the first device I tried the P1 on and that's when I realized this IEM was something special. You can't go wrong with the Hiby R5.iFi Micro iDSD Black Label, this little guy has enough power for pretty much anything. And it has an "xBass” DSP that adds bass without affecting other frequencies. xBass on iFi makes the P1 sound perfect. I can't say much more. Simply better than any IEM I've heard (and I've heard a lot). Drop + THX AAA 789 powered by RME ADI-2 DAC: The most expensive combination in this test. Of course, the P1 sounds great in this combination. And when I really feel the need for a little more bass on the P1 for a recording (which I don't often do, by the way), I use RME's parametric EQ to add some bass. The P1 responds very well to the EQ. The music I tested was local Flac files and Tidal HiFi/MQA streaming. Sample music I tested: Steele Dan - Gaslighting AbbieLorde - RoyalsManu Katche - Keep On Trippin'Blue Deal - Minor Science Fleetwood Mac - DreamsLondon Symphony Orchestra - Shostakovich Symphony No Report - Between the ThighsYosi Horikawa - BumpTom Misch - MovieOTT - Aubergine der Sonne And much more.
