Bluetooth transmitting doesn’t get much more simple than the Miccus Mini-jack TX4. Plug and play at its finest! As is normally the case, great technology once again comes in a small package. Any audio or video source can be easily connected to wirelessly via Bluetooth by plugging a TX4 into the headphone jack.
MINI-JACK TX4 HARDWARE
Just like the Home RTX Mini, unwrapping the TX4 isn’t a life-changing experience. Miccus doesn’t prioritize sleek and artfully-designed packaging, but their product quality makes up for it.
There are only two major components to the TX4, the input and the multi-function button. As I said before, it can be used with any audio source that has a headphone jack. A rotating jack almost guarantees a smooth installation. Just in case your device has an odd connection or a hard to reach headphone input, a convenient extension cable is included. When you’re finished, the swivel jack folds back into the unit for protection and compact transportation.
The swivel jack is great, but the star of the show here is the lone over-sized multi-function button that also serves as an LED indicator light. The LED changes color and flashes different rhythms based on the status. It doesn’t get much more simple than that.
Unlike the Home RTX Mini, the Mini-jack TX4 does not have a dedicated power source. However, unlike most other Miccus transmitter products, it does have an on-board rechargeable battery. A full charge (via the included USB cable) will transmit for about 10 hours. The beauty of the Mini-jack TX4 is that it can be used with practically any audio source, be it a brand new iPad or an ancient tape deck. You might say “I don’t need a TX4 because my device can already transmit a Bluetooth signal.” That may be true, but your device might not feature a low latency codec. If you’re watching movies or binge-watching House of Cards, you’ll want to invest in the TX4 for the highest quality lag-free wireless signal available. APT-X Low Latency ensures that the video and audio are perfectly synchronized.
AUDIO QUALITY AND RANGE
Audio quality is true and rich, as I’ve come to expect from Miccus products. Sound is clear and audio/video lag is virtually non-existent thanks to the low latency audio codec. There’s not much more to say. The Mini-jack TX4 is simple and effective. Although, it does have a very specific job, transmitting (and not receiving) from a headphone jack. It does that one job exceptionally well.
The range is not reminiscent of the powerful Home RTX, but the Mini-jack TX4 can spit out a Bluetooth signal up to 25 or 30 feet if there are no physical obstructions. This is a pretty typical range for high quality Bluetooth transmitters. Not bad for such a small device! The battery life is great, until you forget to turn off the device. Then it will be dead next time you pick it up. Some kind of sleep function would be helpful to compensate for my scattered dad brain.
A cool unexpected feature is that the TX4 can transmit to two devices simultaneously. Most transmitters make you switch between devices manually. So, the TX4 can handle two Bluetooth speakers, two people both listening on Bluetooth headphones, or whatever you need! Overall, it is a great device, albeit one with a very specific purpose.
