Instrument accessories can look comparable on price alone, yet these four choices serve very different jobs. The key decision is whether you need to connect audio gear, replace violin sound posts, or support a Yamaha arranger workstation. Start with the instrument or connection format, then use the listed price as a second filter.
Quick take
- Choose the STX807 7-Meter Professional Audio Cable when a 7-meter XLR cable format is the defining requirement.
- Choose the ProX XC-PXM25 for the explicitly named 25-foot, unbalanced 1/4-inch TS male-to-XLR male connection.
- Choose the 10Pcs Sound Posts set when working with a 3/4 or 4/4 violin and needing multiple wood sound posts.
- Choose the Yamaha SK AW Arranger Workstation Survival Kit for a Yamaha-compatible accessory intended for an electronic keyboard and arranger workstation.

Decision matrix
You are connecting audio equipment. Narrow the choice by cable format and length. The ProX is named as a 25-foot unbalanced 1/4-inch TS male-to-XLR male cable, while the STX807 is a black, 7-meter XLR cable.
You are servicing a violin. The sound-post set is the relevant choice: it includes 10 wood sound posts and is specified for 3/4 and 4/4 violins.
You use a Yamaha arranger workstation. The Yamaha SK AW kit is the focused option, with Yamaha compatibility and an electronic-keyboard/arranger-workstation designation.
Product notes
STX807 7-Meter Professional Audio Cable for Superior Sound Quality
The STX807 fits a purchase where a 7-meter audio cable is needed rather than a short connection lead. Its title identifies the length, and its attributes specify an XLR cable type in black. That makes its role distinct from the violin part and keyboard-oriented kit in this comparison. The limitation is the USD 114.73 listed price, which is the highest of the four choices. It is most compelling when the stated 7-meter format is central to the setup, not simply an optional extra length.
ProX XC-PXM25 25-Foot TS-to-XLR Cable
The ProX XC-PXM25 is tailored to a specific connection: a 25-foot, unbalanced 1/4-inch TS male-to-XLR male cable. Its description also identifies 20AWG oxygen-free copper conductors, giving shoppers a concrete construction detail alongside the named endpoints and length. Pick it when that exact format matches the gear being connected. Its constraint is equally clear: this is an unbalanced TS-to-XLR male cable, so it should be chosen for that named connection requirement rather than treated as a universal cable solution.
10Pcs Sound Posts for 3/4 4/4 Professional Supplies Quality Parts Luthier Tool
This 10-piece set is the clear fit for violin-focused maintenance involving 3/4 or 4/4 instruments. The posts are identified as wood violin sound posts, and the pack count is useful when multiple replacements are needed. Its USD 12.67 listed price is the lowest in the comparison, but its purpose is highly specialized: it is a violin part rather than a cable or electronic-keyboard accessory. Choose it for the stated violin sizes and sound-post format; its listed application does not overlap with the audio-connection needs addressed by the two cables.
Yamaha SK AW Arranger Workstation Survival Kit PRO Audio
The Yamaha SK AW Arranger Workstation Survival Kit is the targeted pick for a Yamaha-compatible arranger-workstation setup. It is identified for an electronic keyboard and carries a Yamaha compatibility designation, giving it a more focused role than the cables or violin sound posts. At USD 35.20, it sits between the low-priced violin part set and the higher-priced STX807 cable. The practical limitation is specificity: its stated use centers on a Yamaha arranger workstation, so it is most relevant when that keyboard context already defines the purchase.
Final recommendation by use case
For a precisely named 25-foot unbalanced TS-to-XLR male run, choose the ProX XC-PXM25. When a 7-meter XLR cable is the core requirement, choose the STX807. For 3/4 or 4/4 violin sound-post work, the 10Pcs Sound Posts set is the appropriate category match. For a Yamaha-compatible electronic-keyboard and arranger-workstation accessory, select the Yamaha SK AW Arranger Workstation Survival Kit. The price range is broad, so compatibility and intended task should lead the decision.
