Venture Electronics impedance adapters review (25 Ohm, 50 Ohm, 75 Ohm). The best audiophile toy?

Before we start checking the Venture Electronics impedance adapters, let me briefly guide you on the concept of an impedance adapter. An impedance adapter adds additional resistance to your signal chain. And it makes some of a certain IEMs and low impedance headphones more usable with a very powerful source.

On a downside, the impedance adapters tend to change the sound signature of the headphone. Generally the larger the resistance the more changes are introduced to the sound. Now that you understand the basic concept of the impedance adapter, let’s look at the VE Super Value Pack .

Disclaimer: I want to thank Venture Electronics for providing the sample for this review. No one paid me to make this review. I don’t offer any specific opinions. And all thoughts expressed in this review are my own.  

Venture Electronics Super Value Pack comes in a simple plastic bag that contains:

• Three 3.5 mm SE adapters (25 Ohm, 50 Ohm and 75 Ohm)
• Three 4.4 mm balanced adapters (25 Ohm, 50 Ohm and 75 Ohm)
• Two 3.5mm to 6.3mm adapters (50 Ohm and 75 Ohm)
• And a standard 3.5 to 6.3 mm adapter

Adapters are well made and I have no questions here. Almost all adapters, except 6.3mm ones, have an impedance marking on the connector. 6.3mm ones come in separate plastic bags and have impedance handwritten, so be careful to not mix them up.

In addition the 4.4mm adapters have color markings on the connector too. The transparent one is 25 Ohm, the red one is 50 Ohm and the black one is 75 Ohm. Also, if you don’t need so many adapters, you can purchase a single impedance adapter from VE too.

The fact VE offers it for sale is not a coincidence. Their portable DAC/AMP Megatron that we covered in the first part of this video is not suitable for IEMs. And it’s a perfect example why you may need an impedance adapter. Megatron is so powerful that if you connect a low impedance IEMs to it, you will be hearing some hiss, which is basically a noise floor. For some people it’s not a problem at all. But those who prefer a dark background will find such a situation pretty much annoying.

In addition, when you are pairing a sensitive headphone or IEMs with a power source, your volume controls become quite limited, as even at low volumes your headphones are too loud and unusable. In addition, your volume ranges  are quite limited, as you need to keep the volume very low and increasing or decreasing it by just one step can easily drag you either into too silent or too loud territory.

Using an impedance adapter in this case, solves both problems, as it adds additional resistance to the signal chain hence the noise floor becomes non-audible and you gain back the range of motion with your volume control.

Now you may ask, what is the need of making so many different adapters. Why not just make a 300 Ohm adapter that will suit everybody? The reason is that the impedance adapters tend to change the sound signature of your headphones, and the more resistance you are adding to the chain, the more changes will be introduced to your sound. So that’s exactly why you need to start with the impedance adapter that adds the lowest resistance and see if it’s enough to solve the pairing problem. If it’s not, you are just stepping up to the next one.

While using an impedance adapter is not a panacea, it solves some of the pairing problems In addition it opens up another rabbit in our hobby, as in my case, experiments with impedance adapters kept me busy for a few days.
