What makes the MP146S spring design better than a standard straight AUX cable?

The TPU coiled jacket retracts to compact length when unused, eliminating loose cable slack that gets trapped or damaged in car consoles. It extends only to the required reach and stores as one neat coil rather than tangled knots.

Can we customize the MP146S for OEM/ODM orders?

Yes. Length, jacket colour, branding and packaging are all customisable for OEM/ODM orders. Contact us with your specifications and order volume.

What are the contact and conductor specifications?

The MP146S features 24K gold-plated contacts for reliable connection and OFC (oxygen-free copper) conductors for high-purity signal transmission.

Is ABS housing suitable for heavy daily use?

ABS housing is cost-efficient and lightweight, ideal for bundled accessories, promotional items and retail lines. For applications requiring a more robust feel and heavy handling, we offer the HMM105S—the same coiled cable in aluminium alloy shell.

Why TPU for the cable jacket?

TPU maintains spring memory while staying flexible in cold weather, enabling reliable coil function without stiffening like rigid jackets would.

Overview

The MP146S is a spring-type 3.5mm to 3.5mm audio lead: a TPU jacket coiled into a spring, an ABS connector housing, 24K gold-plated contacts and OFC high-purity oxygen-free copper conductors.

The coil is the point of the product. A straight AUX lead in a car ends up as slack looped around the gear lever or pooled in the footwell, and it is the slack that gets trapped, pulled and eventually broken at the plug. A coiled lead retracts to a short length when the phone sits in its cradle and extends only as far as the reach demands, so there is nothing loose to catch. It also stores as one compact coil rather than a knot in the console bin.

The ABS housing places this model as the light, cost-efficient build in the spring range. ABS is moulded in volume, adds almost no weight to the plug end, and is the sensible specification where the cable is a bundled accessory, a promotional item or a retail line rather than a heavy-duty daily lead. Where the plug will be handled hard and wanted to feel solid, the HMM105S is the same coiled cable in an aluminium alloy shell.

TPU is what allows the coil to work: it holds the spring memory, stays flexible in cold weather and does not stiffen the way a rigid jacket would.

Each unit ships with one cable. Length, jacket colour, branding and packaging are customisable for OEM/ODM orders.
