4-Conductor 2.5mm male to 3.5mm female TRRS Converter Cable

Pros: Gold connection for higher quality sound. Works perfectly on mobile phones which use the 4 pin connection. One of mine were not identical to the picture (L connection was more smooth and rounded, looks better)

Cons: None, does what is says it should do.

Other: Great for the price, good quality, will definetly buy this again should the need arise.

Pros: Nice cable, fits perfectly my Moto Q.

Cons: You really need a mic+headphone 3.5mm device else you get mono sound (right only).

Other: Would be more useful if it would have been: 4-Pin 2.5mm to 3-pin 3.5mm This way the mic is removed but your normal headset works ok and in stereo

Pros: Shape is nicer than one displayed in picture (rounder) edges)

Cons: Does not work with my Blackberry Pearl 8100.

Other: Build quality seems good, but doesn't work with my phone, and I'm sure it probably won't work with some others.

Pros: *finally be able to use european style headphones on a asian mp3/mp4 player *feels solid, 3,5mm jack fits perfectly

Cons: cable could break proximal of the 2,5mm jack, so handle with care

Other: Top product, VERY usefull and great sound quality (no noise)

Pros: Works with LG VX8300 phone

Cons: Male end of adapter is slightly small resulting in a slightly loose fit Female end of adapter is too tight and requires quite a bit of force to plug in the headphone

Other: Get it for your LG VX8300

Pros: Well built cable that will allow you to plug your 3.5mm 4 pin devices into a 2.5mm 4 pin jack.

Cons: This is not the adapter to buy if you want to use a 3 pin 3.5mm device. Do not get them confused.

Other: Works great for what it is intended to do. No problems so far.

Pros: Good sound quality, and lets you use your standard headphones with all these new mp4's.

Cons: None.

Other: Helpful adapter for anyone wanting to use that $40 pair of headphones with their new mp4 player.
