Manticore/Equinox 700/900 headphone - ear bud options concerns 

Edit: I looked up the chipset and I don’t know what tech they are using on it. There’s a lot going on on that chip. They use chipset Nordic nRF5340. I’m wondering how they locked them to the Manticore and 700/900. In the description of that chip on digikey there is a 2.4GHz proprietary option so maybe they are using that. TN have you tried pairing the Deus headphones to the Manticore? I’m guessing it won’t work but you never know till you try

From the manual for the ML-105 headphones “Minelab ML 105 headphones use wireless technology which delivers faster, higher quality audio than standard Bluetooth. They will give more precise and faster detection responses when used for metal detecting. ML 105 headphones contain the latest nRF5340 chipset to provide a high quality low-latency audio experience.” So it is WiFi tech, not Bluetooth. Explains why you can’t pair your phone with them like the older headphones.

No I haven’t tried.

@@TarnishedCharm The chip manufacture says that Dual-core Bluetooth 5.3 SoC nRF5340 supports Bluetooth LE, and LE Audio. nRF5340 System-on-Chip Dual-core Bluetooth 5.3 SoC supporting Bluetooth LE, Bluetooth mesh, NFC, Thread and Zigbee The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The combination of two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, makes it the ideal choice for LE Audio, professional lighting, advanced wearables, and other complex IoT applications. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® 5.3, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory and integration, while minimizing current consumption. The application processor is optimized for performance and can be clocked at either 128 or 64 MHz, using voltage-frequency scaling. It has 1 MB Flash, 512 KB RAM, a floating-point unit (FPU), an 8 KB 2-way associative cache and DSP instruction capabilities. The network processor is clocked at 64 MHz and is optimized for low power and efficiency (101 CoreMark/mA). It has 256 KB Flash and 64 KB RAM. The nRF5340 takes security to the next level. It offers trusted execution, root-of-trust and secure key storage security features. Arm TrustZone provides trusted execution by implementing a division between secure and non-secure Flash, RAM, peripherals and GPIOs. The state-of-the-art Arm CryptoCell-312 provides hardware-accelerated cryptography, and together with the key management unit (KMU) peripheral, root-of-trust and secure key storage are implemented. The nRF5340 SoC supports an extensive range of wireless protocols. It supports Bluetooth Low Energy and is capable of all angle-of-arrival (AoA) and angle-of-departure (AoD) roles in Bluetooth Direction Finding. In addition, it supports LE Audio, high-throughput 2 Mbps, Advertising Extensions and Long Range. Mesh protocols like Bluetooth mesh, Thread and Zigbee can be run concurrently with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported. www.nordicsemi.com/Products/nRF5340 2.4 GHz radio use: Many of the cordless telephones and baby monitors in the United States and Canada use the 2.4 GHz frequency, the same frequency at which Wi-Fi standards 802.11b, 802.11g, 802.11n and 802.11ax operate. This can cause a significant decrease in speed, or sometimes the total blocking of the Wi-Fi signal when a conversation on the phone takes place. Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. The USB 3.0 computer cable standard has been proven to generate significant amounts of electromagnetic interference that can interfere with any Bluetooth devices a user has connected to the same computer. en.wikipedia.org/wiki/2.4_GHz_radio_use okara gold Hello Dew! I have the Manticore and Tony's earphones that I used constantly on the Nox, and they work just fine on the Manti in and out of the water. I have to say that the ML issued ones are more comfortable and much louder than Tonys. I prefer the MLs but have to use Tonys in the water seeing the others are not waterproof. midalake I have been VERY fortunate to hunt with the Original Black Widow headphones with Audio Sear speakers, for many years. -28 Db on outside ambient noise and some of the sweetest tones ever.

The earcups knock out almost all external noise. This is critical for MANY hunting applications. TexHunter Tom, I've used KOSS QZ-99 headphones for well over 20 years. The passive noise reduction is a key factor... www.dankowskidetectors.com/discussions/read.php?2,185174,page=16 Manticore ML105 Headphones ML105 Headphones in specific and not just the BT chipset like the last link. So the ML-105's are Chinese rebadged headphones again, from Qinlian Electron Limited, NO 233, Shizhou Road, Shipai Town, Dongguan city, Guangdong Province, China. And the factory Dongguan Desheng Industrial Co., Ltd. This means we'll likely be able to pick up extra sets off Aliexpress really cheap. They're Bluetooth LE using GFSK 1Mbps and GFSK 2Mbps www.detectorprospector.com/forums/topic/19696-new-minelab-manticore/page/95/#comments As for the headphones/Bluetooth LE, am I reading this correctly that the headphones aren't proprietary AFTER ALL, and that as more headphones that are Bluetooth LE-capable hit the market, we'll likely have other, compatible options if the ML-105 won't do it for us? www.detectorprospector.com/forums/topic/19696-new-minelab-manticore/page/96/#comments

@@TarnishedCharm Looks like Minelab plans to sell waterproof headphones. I don't see why we can't use another manufactures headphones, less the connector overmold must be less than 9 mm in diameter. Any standard 3.5 mm (⅛‑inch) headphones can also be connected to MANTICORE, however the headphone connector overmold must be less than 9 mm (0.35") in diameter, otherwise the connector will not fit inside the waterproof Headphone Socket 6.35 mm (1/4‑inch) headphones can be used with MANTICORE via a headphone adaptor, available as an accessory. CONNECT WATERPROOF HEADPHONES MANTICORE and the Minelab 3.5 mm (⅛‑inch) waterproof headphones can be fully submerged to a depth of 5 metres (16‑ft). Minelab waterproof headphones (not included) must be used for underwater detecting because they have a unique connector that forms a waterproof seal when connected to the MANTICORE Headphone Socket. pg 64. www.minelab.com/__files/f/494362/4901-0428-1%20Inst%20Manual
