Verkaufe meinen gerade erst neu erworbenen IEM Dunu Koto Ito, ein IEM mit zwei dynamischen Treibern und zwei Balanced Treibern.
Nur kurz getestet (mit eignen Ohrstöpseln, die originalen sind ungenutzt.
Bin aktuell ein wenig in meiner Basshead-Era, daher auch sehr an dem Fatfreq x HBB Deuce interessiert und würde einen Tausch in Betracht ziehen!
Privatverkauf, daher keine Rücknahme oder Gewährleistung jeglicher Art.
It's a buyer's market for used Fatfreq gear right now, with solid recent EUR comps clustering around a median of €215 (25th percentile €185, 75th €245). At €155 in excellent used condition, this Duno Koto Ito undercuts the low end handily—call it a genuine bargain if it's as clean as claimed, especially versus its new price tag.
Before biting, verify the driver integrity with a frequency sweep; Fatfreq portables like this can develop subtle distortion from overdriven bass after 1-2 years. Confirm the full kit comes with original cable, tips, and case—replacements add up quick. Test for microphonics on cable flex too.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
FATfreq is a Singapore-based in-ear monitor manufacturer headquartered in Chinatown at 29A Mosque Street. The company emerged from roots in professional audio, originally designing IEMs for stage and recording musicians before expanding into the consumer audiophile market. While specific founding details are not readily available, FATfreq has established itself as a serious player in custom and universal IEM design and manufacturing, with all production handled in-house in Singapore.
The brand specializes exclusively in in-ear monitors, offering both custom-fit (CIEM) and universal (UIEM) models. FATfreq has gained particular recognition for its Maestro series, which targets what enthusiasts call "audiophile basshead" listeners—those seeking substantial low-frequency output without sacrificing overall audio quality. The company employs proprietary tuning technologies to achieve notably elevated bass performance across its lineup, distinguishing it from more neutral-tuned competitors.
FATfreq occupies a niche boutique position within the hi-fi ecosystem, commanding a devoted following among discerning IEM enthusiasts rather than mainstream consumers. The brand's reputation rests on technical innovation, handcrafted construction, and a willingness to prioritize bass-forward tuning for a specific listener demographic. Its Singapore manufacturing base and direct-to-consumer approach position FATfreq as a premium, independent alternative to larger multinational audio companies, appealing to audiophiles who value both sonic character and artisanal production values.
