Little Bear is a budget-oriented audio brand operated by Shenzhen Cavins Technology alongside its sibling brands Nobsound and Douk Audio. The lineup centers on compact, tube-based gear aimed at home hi-fi and headphone listeners, including the T7, T10, and T11 MM phono preamps, the B4 and balanced B4-X portable vacuum tube headphone amplifiers, and the P14 four-channel headphone amp.

Beyond amplification, the brand produces a range of passive signal-routing boxes such as the MC2, MC3, and MC104 XLR/RCA switchers and splitters, plus analog VU meter units co-branded as "One Little Bear." A smaller line of guitar effects pedals has also appeared under the Little Bear name, including the R.Attack RT-2 distortion and the G3 tube overdrive.

The brand has built a following among DIY and modding communities on forums like Head-Fi, diyAudio, and Vinyl Engine, where its affordable tube designs are frequently discussed as platforms for tube rolling and circuit upgrades rather than finished reference-grade products. Distribution is handled primarily through Amazon, eBay, AliExpress, Reverb, and the Douk Audio web store.

Little Bear has 5 products cataloged on Equipboard, including Headphones & In-Ear Monitors, Distortion Effects Pedals, and Bass Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Sergio D German and Merkaba.
