LETSHUOER S12 PRO

The reviewer finds the S12 Pro to be an excellent planar IEM, though it is only a subtle evolution of the original S12 with minor tuning tweaks and a new modular cable. It retains the S12's bright, clear signature and is among the reviewer's top three current planar IEMs, though the differences from the original are so small that owners of the S12 may not need to upgrade.

The reviewer concludes that the S12 Pro is essentially the original S12 with a modular cable upgrade, not a retuned version. They note it has slightly more bass than the S12 but falls within unit variance, and while it's a good set, it has been surpassed by newer models. They suggest buying the cable separately if possible rather than upgrading from the S12.

The reviewer is highly impressed with the Letshuoer S12 Pro planar IEMs, praising their excellent technical performance, balanced and natural tuning, and high-quality accessories. He finds them very comfortable and believes they are well worth the $152 asking price, giving them a strong recommendation.

The reviewer praises the LETSHUOER S12 Pro planar magnetic IEMs for their excellent bass response, detailed mid-bass, and overall sound quality, claiming they outperform many more expensive headphones. They highlight the impressive build, accessories, and cable, while noting the need for a powerful source to drive them properly. The main criticism is the exposed flush-mounted two-pin connectors, which are prone to moisture damage.

The reviewer finds the LETSHUOER S12 Pro to be a refined and well-balanced planar IEM, praising its improved treble, tight bass, and clear vocals. They consider it their favorite planar of 2022 and a top contender in its price range, recommending it for both everyday listening and light reference work.
