Ukuncintisana Kweqiniso Kwe-Bose QC-15?
Enye yezinkathazo kimi njengombuyekezi wekhanda - futhi njengomsizi we -headphones-ukukhansela umsindo - ukuthi kunzima kakhulu ukutusa noma iyiphi imodeli ye-NC engaphezu kwe- Bose QC-15 . I-QC-15 inenhlanganisela yokuwina induduzo enkulu kakhulu, umsindo ongenakulinganiswa wokukhansela, ikhwalithi yezwi elihle kakhulu kanye nokuphatheka kahle. Ungathola imisindo ye-NC ezwakalayo kangcono (njenge-PSB M4U 2) kanye nezinkinobho ze-NC ezihambelanayo (njenge-AKG K490 NC), kodwa awukwazi ukuthola into eyanelisayo ku-QC-15.
Ngangingazange ngilindele ukuthi i-headphone evela ku-Samsung ingaba ngowokuqala inselele ngempela i-QC-15. Yiqiniso, i-Samsung ngumholi kumaklayenti kagesi, kodwa i-headphone ingenye yezindawo ezimbalwa lapho engazange abe ngumdlali. Kodwa lapho nginikeza i-Level phezu ukulalela okusheshayo, umdlandla wami wagijima ngokusheshisa.
Angizange ngithole ithuba lokuhlola okubanzi iN Level Over, kodwa ngisebenze izilinganiso ezimbalwa futhi ngisebenzela wonke amathrekhi wokuhlola engiwuthandayo ngawo. Nakhu engikutholile.
Ngokubanzi, i-level Over inezwi elijwayelekile elisemaceleni nelingathathi hlangothi, yilokho kanye nami (futhi, mhlawumbe, abalaleli abaningi) abafuna kumakhalekhukhwini. Imaphakathi, ikakhulukazi, yayihlanzekile ngokumangalisayo. Amazwi azwakala ngokwemvelo kunokuba abe nemisindo eminingi yokukhansela umsindo, ngaphezulu emgqeni walokho engikujwayele ukuzwa kusuka kuma- headphone amahle. Umbala owodwa we-sonic engiwuzwayo ngamazwi amancane, futhi wamukelekile: ukukhushulwa okuncane noma "ukuphakama okukhona" endaweni ephansi, cishe u-3 kHz. Lokhu kwenza abaculi abanobuhle obufana noJachard Taylor kulula ukuwaqonda, nakuba kwakwenza ukuqoshwa okuzwakalayo okuzwakalayo okufana nezwi lika-Toto "Rosanna" elikhanyayo kunalokho engingakukhetha. Yenza futhi isiginci sikaCharles acoustic siphume kancane. Kodwa futhi, lezi yizinhlobo zemidwebo ongayithola ngisho nama-headphone amahle kunazo zonke kulolu hlu lwamanani.
Kwakungekho umehluko omkhulu umsindo ngomsindo wokukhansela noma ukuvala. Ngempela ngithandile kangcono nge-NC on. I-NC ibonakala sengathi iqinisa imisipha kancane kancane, ihlinzeka ngokuxuba okuphelele (ngokunambitha kwami, okungenani) kokuhleleka kwamandla namandla. Njengoba i-NC off, ama-bass ayezwakala kancane kancane.
Ngingabaza ukuthi ubani ozozulazula ngemininingwane ephakeme ye-level Over and air, kodwa akekho oyoyibiza ngokuthi i-edgy noma i-harsh. Ukuhamba okuphezulu kubonakala sengathi kuthulisiwe kancane, hhayi okwanele ukushintsha ibhalansi ye-tonal, kodwa ngokwanele ukuthi umsindo awukona konke okwehlukile kimi. Kodwa kaningi kunomsindo wokukhansela i-headphone, i-PSB M4U 2 yiyona kuphela engingayicabangela.
Ngokuvamile, ngingasho ukuthi lena yilezi zingcingo ezingcono kakhulu ezizwakalayo ze-NC engizizwile - hhayi okuhle njenge-M4U2, kodwa ivulekile kakhulu. Kungcono kune-QC-15? Ngangingenayo i-QC-15 esandleni sokuqhathaniswa, kodwa i-Level Over ibonakala sengathi izwakala kancane okubandakanya kunalokho engikukhumbulayo kusukela ezindizeni zami ezigqoka i-QC-15.
Manje ake sibone ukuthi lilinganisa kanjani ........

Izinyathelo ezingaphezu kwezinga: Impendulo ye-Freqeuncy
Ukukala i-Level Over, ngasebenzisa i-GRAS 43AG yami indlebe / itekisi simulator, i-analyzer yomsindo we-Clio 10 FW, ikhompyutha ye-laptop ye-TrueRTA nge-interface ye-M-Audio MobilePre ye-USB, kanye ne-Musical Fidelity V-Can isikhulumi sekhanda le-headphone. Ngalinganisa izimpendulo zokuphindaphinda izimpendulo ze-reference reference point (ERP), cishe iphuzu esikhaleni lapho intendeni yesandla yakho ihamba khona nge-axis endlebeni yakho yezindlebe uma ucindezela isandla sakho ngokumelene nendlebe yakho.
Ishadi elingenhla libonisa ukuthi impendulo yekhanda le-headphone ihluka kanjani nemvamisa. I-trace eluhlaza yimpendulo nge-NC off, i-trace eluhlaza okwesibhakabhaka i-NC on. Ijaji lika-Jury lisekhona kulokho okushiwo "impendulo" yekhandaphone. Kodwa i-headphone ehambisa impendulo esiseduze nomugqa wezintambo, mhlawumbe ukuthuthukiswa okuncane ezindaweni ezincane kanye nokunye okukhushulwa cishe cishe ku-3 kHz, kuvame ukuzwakala kahle.
Impendulo ye-Level Over iyamangalisa, futhi iminyene emaphakathi phakathi kwe-400 Hz no-2 kHz (noma ukuphakamisa okuncane nakwezinye izindawo, kuye ngokuthi uyibheka kanjani). Yini okubaluleke nakakhulu ukuthi impendulo ayiguquki neze nge-NC noma ivaliwe. I-PSB kaPaul Barton ingitshela lokho ngempela, kunzima kakhulu ukuyenza, nokuthi iqiniso lami engivamile ukubona lezi zilinganiso zihambisana kakhulu nobufakazi bokuthi uqinisile - nokuthi kukhona umzamo omkhulu wobunjiniyela ngemuva kweNqanaba Over.

Izinyathelo ezingaphezu kwezinga: Ukuhlukanisa
Leli shidi libonisa ukuhlukaniswa (noma umsindo wokukhansela umsindo) we-Level Over (i-trace eluhlaza okwesibhakabhaka) ngokuhambisana ne-Bose QC-15 (i-trace green). Izinga elingezansi ku-75 dB likhombisa ukunakekelwa komsindo wangaphandle - okusho ukuthi, 65 dB eshadini kusho ukunciphisa -10 dB emisindeni engaphandle kule mvamisa. I-line engezansi ishadi, kungcono.
Ngcono kakhulu kokukhumbula kwami, i-level Over iwukuphela kwekhanda le-smartphone engiyihlolile ukuthi lilingana kakhulu nomsindo wokukhansela umsindo we-QC-15 "ye-jet engine band" phakathi kwezingu-100 no-200 Hz. Ngokwezilinganiso engizithathile ezindizeni, yilapho iningi lezinjini ze-jet lihlala khona, futhi i-Level Over yenza umsebenzi omuhle wokuyiqeda. Ibuye ihlinzeke i-QC-15 ukugijima ngemali yayo kuma frequencies aphezulu kune-1 kHz, nakuba i-QC-15 inenzuzo ecacile phakathi kuka-200 Hz no-1 kHz, nangaphansi kwe-100 Hz. Ukushesha ukulalela umsindo we-pink ovela esivivinyweni sami sokuqinisekisa uqinisekisile ukuthi umsindo weNqanaba Over ukhansela kuhle ngaphezu kwesilinganiso. (Futhi, angizange ngibe ne-QC-15 esandleni sokuqhathaniswa okuzithobayo.)
Ngokombono we-ergonomics, i-Level Over ibonakala izinyathelo ezimbalwa ezansi ukusuka ku-QC-15, ikakhulukazi ngoba ayifuni ipulazi ngakho-ke ikhululekile ukuthutha futhi ikhulu kakhulu ukuze ivumelane kahle emasakeni amaningi e-laptop.
Kodwa ngokombono wezimpawu, i-Level Over ishaya kalula i-QC-15. I-Level Over isebenza (namanje izwakala kahle, ngisho) uma ibhethri layo elayishwayo lihlehla phansi, okuyinto i-QC-15 ayikho. Futhi i-Level Over ine-wireless ye-Bluetooth, okungaphezu kwalokho abanye abantu abakutshele ukuthi empeleni izwakala kahle, njengoba ungakuzwa ekuvivinyeni kwami kokulalela okuyimpumputhe .
Ngifisa sengathi ngingaba nesikhathi esiningi sokusebenzisa nge-Level Over - futhi kangcono nakakhulu, indiza yokuyithatha. Mhlawumbe ngolunye usuku ...
