Impressive Clarity With Four Custom-Designed Balanced Armature Drivers:-

With four custom-designed balanced armature drivers on each side, the Hidizs MD4 brings a charming acoustic performance. The pair produces a punchy lower end with a rich midrange and a smooth, lively treble region. It complements different genres of music well with its unmatched clarity and professional tuning.

Precisely Adjusted Three-Way Frequency Crossover:-

The four Custom BA drivers on the MD4 are arranged in a professionally designed three-way frequency crossover. It allows each driver unit to work with full accuracy and results in lower distortion in the output signal. The precisely adjusted frequency crossover band reduces any frequency overlapping issues and presents with a clean performance.

3D-Printed Acoustic Tubes:-

Hidizs has redesigned the acoustic structure of the MD4 ear shells. They have featured 3D printed straight acoustic tubes that ensure continuous and clean audio transmission with low signal loss during the transmission. 

Dual Tuning Switches For Four Tuning Adjustments:-

There are two tuning switches at the back of the ear shells. They allow the users to easily adjust the output tuning bringing four different tunings in a single pair of earphones. The pair can be adjusted for balanced, warm, Treble enhancing, and bass-enhancing tunings.

Exquisite Craftsmanship:-

Hidizs is well-known for its outstanding craftsmanship. The brand has designed the latest MD4 using handmade celluloid face plates, CNC machined aluminum alloy middle frame, and aluminum alloy ear nozzle. MD4 looks stunning, it is available in three striking color options.

Comfortable & Ergonomic:-

The connector on the included stock cable adopts an elbow-shaped design for an ergonomic fit. The cable turns around your ears and makes the earphones sit into your ears firmly. Hidizs has designed the ear shells in ergonomic shape for a comfortable wearing experience.

High-Quality Cable:-

Hidizs MD4 comes packed with a high-purity mixed hybrid cable. The cable has a 4-core braided design with 60 high-purity silver wires and 60 high-purity OFC wires tightly twisted together. It uses standard 0.78mm 2-pin connectors and a 3.5mm single-ended termination.

Great toy
Color: Pawty
My dog loves this toy. I was pleasantly surprised to see it was a decent size for a stuffed toy, and not tiny. It seems pretty sturdy as my dog can shred some stuffed toys, but this one is still standing with the squeaker intact. The rope is securely attached within the toy and my dog likes to play some tug-of-war with it. Would recommend to other pet parents.

Husky approved!
Color: Cheers
Got this for my large husky to wear for his 10th birthday. He didn't tear it up right away. The squeaker lasted longer than it does with most toys. He seemed to genuinely enjoy the toy. Removed the stretchy string once I got a few pictures so he wouldn't eat it. Very cute.
