Razan's audio reviews

Last edited: November 2nd, 2025 (razan/zerostresslevel)

I have always been asked at some point by newbies in audio who look for headphones or IEMs for gaming. Honestly, when asked this over and over again, it really becomes irritating for the ones giving the advice to newbies who only plan to use the audio gear for gaming. But here is what I'll say: It doesn't matter. The best "gaming" headphones or IEMs is the one you like the most. Why? I will elaborate this throughout the rant. Audio in games has basically become inevitable at this point. Whether it's a competitive game like CS2, a mostly single-player game like Elden Ring or lots of rhythm games like osu!, audio gear always enhances the experience with these games in comparison to no audio gear . It's also inevitable that a lot of influencers will recommend certain headphones or IEMs for specific games. But why doesn't it matter? First of all, as audio is a highly subjective thing, there is no such thing as the best headphones/IEMs for any person . Believe ...

This Floaudio Lily is bought using my own money in the Floaudio IEM Store on AliExpress.

These IEMs are likely to come to mind first if you're asking for budget IEM recommendations on an audio forum or something alike. What doesn't come to mind for a lot of people, though, is something like the IEMs about to be reviewed: the Floaudio Lily. Floaudio Lily is a 50-dollar (or lower-priced) set of IEMs that uses one single balanced-armature driver on each side. It uses 3D-printed resin for the shell material. It comes with 3 pairs of eartips, each pair being a different size (S, M, and L). Lily has a sensitivity of 98dB/mW with an impedance of around 16 ohms. Additionally, Floaudio Lily als...

This Koss KSC75 unit was purchased from the kopfhoererboutique audio store in Vienna, Austria. Table of contents Introduction Looks, build and comfort Sound quality For the clueless: How audiophiles describe sound Tonality Technicalities Modding Comparisons Koss KSC75 vs Koss PortaPro Koss KSC75 vs Sennheiser HD650/6XX Conclusion Introduction When selecting a pair of headphones, many tend to overlook options under 100USD because most of the headphones in this price range lack proper research into the drivers of the headphones, making a lot of them sound rather unnatural, bassy or too sharp. That's why lots of people opt for models like the AKG K361, Sony MDR-7506, beyerdynamic DT770 Pro and audio-technica ATH-M50x for closed-back options, and Sennheiser HD560S, Sennheiser HD6XX (USA only) and beyerdynamic DT880 Pro for open-back options. But what if your budget on headphones is limited to 100USD and you can't go overbudget? Meet the Koss KSC75. Koss KSC75 is one of the sequels ...

The Letshuoer S15 reviewed in this review is the demo unit of the kopfhoererboutique audio store in Vienna. Letshuoer S15 is Letshuoer’s newest entry in the Planar IEM world, coming at the cost of 329 USD. It contains a new generation 14.8mm Planar driver and a diaphragm as a filter (aka. "6mm R-Sonic Passive Filtering Module"), marketed as a "technological breakthrough". But is it worth it? Build and comfort The S15 is made out of a metal faceplate and a 3D-printed shell, which feels a little bit more premium than the “normal” plastic builds which you can find on cheaper IEMs. It comes with a cable which is basically a mix of a S12 Pro and EJ07M cable (S12 Pro cable with EJ07M L-plug). Furthermore, the cable is modular, so you can switch the cable from a 3.5mm Single Ended one to a 4.4mm Pentaconn or 2.5mm Balanced cable if you want to. The set of IEMs actually fit weirdly in my ears. I had to toss the IEMs a little bit to get a secure, non-fatiguing fit – and ...
