Head Gear Reviews by BonGoBiLai
  1. Questyle CMA18 Portable / CMA18P

    5.00 star(s)
    Questyle is a highly consistent brand that has only produced bangers and not a single bad apple. This brand used to be a bit obscure in the Western market (probably due to a lack of distributors and the absence of proper marketing), but its fame was actually catapulted by the M15 portable dongle DAC Amp. The much higher-end CMA 15 and CMA 12 Master generally received positive responses. While I am not a “fanboy” per se, I found them to be excellent products without any significant flaws. However, none of them necessarily blew my mind. That was until...
  2. LETSHUOER Cadenza 12

    5.00 star(s)
    Letshuoer is a Chinese IEM manufacturer and they are among the most consistent performers in the budget/mid-fi chi-fi scene. I have tried almost every significant IEM Letshuoer has come up with so far. Starting from the divisive and not particularly well received ‘’Tape’’ to modern cult classics like S12 and S12 Pro. I also got to try the S15, EJ07M and DZ4. All three had fantastic tuning. (The EJ07M I specifically adored.) Given my experience with their prior releases, I am quite confident to give my verdict that Shuoer has pretty much struck the...
  3. ISN G4 IEM cables

    5.00 star(s)
    Background ISN is a familiar name among cable aficionados who spend moderate amounts on cable but do not go full-crazy with their wallets. ISN also makes a few IEMs, some of which were huge hits, H40 for example. This review will focus on the ISN G4, a ‘midrange’ cable from ISN that sits comfortably in between their flagship ‘Solar’ and super budget ‘H8’ cable. I understand there is skepticism surrounding cables and their effects on sound. Therefore I’d try to cover both the ergonomic/build/aesthetics aspects and sonic aspects of the G4 in this...
  4. Flipears Artha

    5.00 star(s)
    I have reviewed the Flipears Aether recently and proclaimed my unwavering love and adulation towards that IEM. To me, it is the best overall IEM under 1500 USD. When you set up a bar so high with a 700 USD ‘’budget’’ IEM, where do you go from that, especially with a hefty price tag of 1700 USD? Artha retains almost the entirety of the tonal characteristic of Aether, while simultaneously bettering it in terms of technical prowess. It has some quirks up its sleeve too! Let’s dive in.

  5. Spirit Torino IEM TWIN PULSE BERYLLIUM

    4.50 star(s)
    Background: Spirit Torino is a brand from Italy that has always been mysterious yet respectable. Their headphones are known for bold and flashy aesthetics, great build quality, and meticulous craftsmanship. However, due to availability issues in this part of the globe and the highly expensive price tags, I have not been able to try out any full-sized Spirit Torino headphones yet. I was therefore very excited to get my hands on the Spirit Torino Twin Pulse Beryllium IEM which is essentially their first foray into in-ear monitors. But how does it...
  6. Flipears Aether

    5.00 star(s)
    Filipino people in general are ardent hobbyists and I interact with them often in audiophile forums. I am somewhat embarrassed to admit that I have been barely aware of their domestic high-end offerings. Flipears is an IEM boutique from the Philippines that specializes in custom IEMs primarily intended for audio engineers and musicians. They are not particularly well known outside of their native borders as they never really operated internationally via vendors until very recently. However, Flipears was a participant at the Canjam SoCal 2023 and I...

  10. KiwiEars Quintet

    4.50 star(s)
    Kiwi ears is an in-house brand from Linsoul that has made quite the name for themselves within a short period of time. Their previous releases, Cadenza and Quartet was quite well received. Will the 219.99 USD Quintet continue that streak? I’d try my best to be as transparent as possible and not gloss over things that shouldn’t be glossed over. Let’s dive in.

  13. Symphonium Helios

    5.00 star(s)
    Founded in 2015, Symphonium is a relatively new IEM brand from Singapore. Currently they are offering only 5 models on their website, Helios being the flagship costing $1099. Since its release, Helios has been receiving lots of praise and accolades everywhere which is well deserved in my opinion. Alongside its strengths, it does have a few drawbacks that I will discuss as well. Let's dive in. Disclaimer: I am posting this review as a co-reviewer at Amplify Audio Reviews, a passion project by my friend Mr. @Sajid Amit . You can check out his videos...
  14. final ZE3000

    2.50 star(s)
    So, I have been using the Final ZE3000 for more than 20 days (About 90 hours in total) and whoo man, its been a tough week. The ‘Shibo’ finish feels premium. Both the buds and the case feel well built as well (except the lid mechanism. flimsy and cheap). While the case form factor is nice and pocketable, its an absolute nightmare as soon as you open the lid. The buds themselves don’t have any strong anchoring point when they are in the case and the lids don’t open enough to get them out comfortably. This is already a hassle when you are stationary...
  15. Questyle CMA Fifteen DAC/Amp

    5.00 star(s)
    Questyle is one of those rare brands that is yet to release something that isn’t impeccable. They have a very small catalogue that offers only a handful of products but whenever they come up with something new, it's bound to be a guaranteed hit. I think this exemplary consistency correlates well with their very conservative product release practice where quality and polish takes utmost priority as opposed to flooding the market with subpar products every other week. I have tried and owned both their dongles (M12 and M15) and had long trial sessions...
  16. Questyle M15 · Mobile Lossless Headphone Amp with DAC

    5.00 star(s)
    Dongles have suddenly skyrocketed in popularity after Apple decided to ditch the headphone jack in favor of airpods (which worked flawlessly as airpods generate unbelievably huge amounts of revenue and profit for Apple) and the whole smartphone industry followed suit. Initially there were only budget options; Cheap, decent but also rough around the edges and underpowered. But in recent months, we have observed a sudden boom in ‘premium quality’ dongles costing 150-400 USD that are somewhat blurring the line between ultra portability and mid fi...
  17. Tripowin x HBB Olina

    3.50 star(s)
    Olina has been all in rage lately and is being commonly touted as the new sub 100 USD benchmark. Is it really though? Olina is the 2nd collab between reviewer HBB (Badguygoodaudioreview on YT) and Tripowin. There are generally a lot of hype when a reviewer's name is involved. We have observed such hype after Crinacle tuned stuff had been released. Well, my experience with Olina is a mixed bag to be honest. There are a lot of good qualities to it but also a few caveats that can honestly be quite jarring at times. Unboxing experience was good. I...
  18. HIFIMAN Edition XS

    5.00 star(s)
    Hifiman struck consecutive golds with the release of two high end planar magnetic headphones a few while back, Susvara and Arya Stealth. Both adopted Hifiman’s Stealth Magnet design which is supposed to provide clean and spacious sound, devoid of any sort of wonkiness resulting from magnetic interference. Both headphones have natural, lifelike timbre and class leading technical prowess to compliment that. So when Hifiman released the Edition XS which adopts the same stealth magnet tech as its predecessors, that too for only 499 (literal half of...
  19. DUNU Titan S

    3.50 star(s)
    I recently got the Titan S, a 79 USD single DD IEM from Dunu. I have tried and owned a few Dunu IEMs before. I used to own a DK 3001 pro which I liked and appreciated at that time. I don’t think it aged that well given the abundance of better options available now. I tried SA6 for a few weeks, which is still relevant and a good monitor. I had the Dunu Zen for a while and was not a fan, at all. So given all the mixed prior experience, my anticipation for Titan S was cautiously optimistic. Titan S is not the first iem in the Dunu line up with Titan...
  20. Softears Volume

    4.50 star(s)
    To be frank, volume's FR graph is a bit scary therefore I was cautiously optimistic. First time I put them on, I was impressed but not completely amused. Fast forward and now I am completely bedazzled and listening to it non stop. Midrange on this is easily among the absolute best I have heard in terms of timbre, clarity and transparency, blows almost everything away under 500 USD. Lower midrange is not as full as HD650 or IER M9 and more emphasis is given to the upper midrange and lower treble (rest assured, there is hardly any shout or jaggedness...
