Easy to use,good sound



Great, Positive connectors!

Granturis from Washington on 6/28/2015

Crutchfield Customer Review (What's this?)

I have a Peachtree amplifier, and Martin Logan electrostatic speakers. Previously I had purchased Monster banana plugs to use with 14 GA wire for the speaker hook ups. The banana plugs worked great on the amp, but just didn't quite fit correctly on the spring-type terminals on the speakers. The flex-pin type work great, and provide a neat, positive connection. Sounds great!

Pros: Simple to use, and when used with the proper gauge of wire, they make a great sounding and much less expensive alternative to some "speaker cables"!

Cons: None.

Great product for Monster cable! I've tried several other connectors and they were difficut to attach or did ot last. These went on fast, easy and really bring out the sound.

Monster flex pin connectors

RB from Ashburn, VA on 11/15/2013

Crutchfield Customer Review (What's this?)

Expensive but worth it.

Pros: They do not pull apart, and are high quality. Would be 5 star except for the con - instructions.

Cons: If you strip the cables the length they instruct, you will stab your fingers trying to tuck the cable strands around the post, over the flange. Strip slightly less and it works fine.

Cons: None

Great invention

Joe from Lake Stevens, WA on 9/8/2013

Crutchfield Customer Review (What's this?)

The monster cable QUICK LOCK connectors work well in tight on wall speaker applications. I tried the banana connectors and they wouldn't bend to fit. These did no problem. Much better than threading bare wire in tight speaker connectors 6 ft. up on the wall.

Pros: Nice and easy to use

Cons: none

Easy, Clean connections

Picky John from Chicago, IL on 5/11/2013

Crutchfield Customer Review (What's this?)

Great way to terminate speaker wire for easy connections to speakers and receivers. Makes it easy for connecting and reconnecting into tight places. The gold connectors don't tarnish ensuring a solid connection versus copper that can tarnish with time. I ordered two more pairs to use for my other speakers to the receiver.

Pros: Easy to attach to speaker wire. Easy to use. Wires terminated with these connectors are great for initial and future uses. Two pairs of color coded connectors help mark the wires so the phasing is right.

Cons: A little pricey, but worth it.

Monster connector pins

Sal from Discovery Bay on 3/26/2013

Crutchfield Customer Review (What's this?)

Nice product, easy to use. Unfortunately the terminals on my amp are too close together to use these as they will touch. Good product though.

Pros: Quality, easy to install

Cons: Exposed metal, not recommended for tight areas.

Great connectors with good price!

PR Audio from Caguas, PR on 1/13/2013

I do a lot of DIY cables, interconnects, etc. I use high quality products, same as the really expensive brands. Not a fan of Monster products as my experience have been that they are overpriced and same quality as other less expensive brands. But, when it comes to their QuickLock products, they are excellent and a great value. High quality, no need to solder, easy to use, and get the job done. This Flex Pins are better than rigid pins that break with time. Rigid pins can also touch each other in vintage gear or equipment where there is not much spacing between + and -. Great product from Monster!

Pros: No soldering, high corrosion resistance. good conductivity, priced right, easy to use, rubber isolation (black part), no tools needed, and accepts thick gauge wires.

Cons: Does not lock well wires that are 16 AWG or less.

Best Thing Since Sliced Bread

SteveK from Central, SC on 3/10/2012

Crutchfield Customer Review (What's this?)

About a year ago I bought a new Yamaha receiver and CD player from Crutchfield. Along with that, I got some Monster QuickLock Banana Connectors to use with some existing Monster Cable run to my vintage Infinity speakers (recently refoamed). The banana connectors worked great with the receiver, but were too large to fit the old terminals on the speakers. So... I just made a bare wire connection to the speakers (like in the old days), until I came across these flex pin connectors. They are appropriately named & solved the problem. I'm not an idiot, but I would say these connectors are pretty much "idiot-proof". Monster produces the highest quality & most easy-to-use cable and connectors I have ever purchased. Crutchfield service, just as always, was fast, accurate and professional.

Pros: high quality, ease of use, quick attachment

Cons: Are you kidding?!...NONE!

Monster QuickLock™ Self-Crimping Flex Pin Connectors

Susie from Indio, CA on 6/28/2009

Crutchfield Customer Review (What's this?)

I was really frustrated trying to connect our stereo speakers. We had had a handyman do the job originally. We weren't getting sound out of both speakers (in-ceiling type). So, I took on the job to figure out why. I couldn't get the speaker wires to cooperate and land in the spot for the pinch clamp to hold and knew there had to be a better way. I searched and found these connectors. I ordered enough to do the whole setup and found them very easy to install. I was able to get sound out of all of our speakers within an hour! I carefully labeled the wires so that if we disconnect in the future, I can reconnect without any problems! THANK YOU for a great product!
