Ukhuphiswano Lwenene Bose QC-15?
Enye yezinto eziphazamisayo njengombuyekezi wamakhanda-kwaye njengomtsalane we -headphones-ukukhansela i-headphones - kukuba kunzima ukucebisa nayiphina imodeli engaphezulu kwe-NC ngaphandle kwe- Bose QC-15 . I-QC-15 inokudibanisa inqabileyo yentuthuzelo, ingxolo engenakulinganiswa yokukhansela, ikhwalithi ephilileyo kunye nokuphatheka. Unokufumana i-headphones ze-NC ezibhetele kangcono (njenge-PSB M4U 2) kunye ne-headphone ze-NC ezihambelana ne-NC (njenge-AKG K490 NC), kodwa awufumani into eyanelisayo kwi-QC-15.
Ngokuqinisekileyo andizange ndilindelwe ukuba i-casphone evela kwi-Samsung ingaba ngowokuqala ukuba umngeni kwi-QC-15. Ngokuqinisekileyo, i-Samsung iyinkokheli kumthengi we-electronics, kodwa i-headphones yenye yezona ndawo ezimbalwa apho engazange abe ngumdlali. Kodwa xa ndinikela iNqanaba ngaphezu kokuphulaphula ngokukhawuleza, inzondelelo yam yakha ngokukhawuleza.
Andizange ndifumane ithuba lokwenza uvavanyo olubanzi kwiNqanaba elingaphezulu, kodwa ndandiqhuba imilinganiselo embalwa kwaye ndiqhuba onke amathrekhi wam okuthandayo ngawo. Nantsi into endiyifumeneyo.
Ngokubanzi, iNqanaba elingaphezulu linomsindo ongezantsi kwaye ungathathi hlangothi, oko kanye kanye (kwaye, mhlawumbi, ngabaphulaphuli abaninzi) bafuna kwi-casphone. I-mids, ngokukhethekileyo, yayingcolileyo. Iimvalo zavakala kakhulu ngokwemvelo kunokuba zininzi zentsimbi-ukukhansela i-headphones, ngakumbi kumgca wento endiyisebenzisayo ukuva kwii- headphone ezintle. Omnye umbala wendodana endiyivile ngezwi wayemncinci, kwaye wamkela: ukunyuka okufutshane okanye "ukufika kwintlanzi" kwindawo ephantsi, malunga ne-3 kHz. Oku kwenza izandi ezizenzekelayo ezinjengeJachard Taylor zilula ukuqonda, nangona zenze iirekhodi ezivakalayo ezizwakalayo njengeToto "Rosanna" izandile ngakumbi kunokuba ndithandayo. Kwakhona kwenza isiginci sikaTyloric acoustic sandile. Kodwa kwakhona, ezi ziintlobo zeemibala ongayifumana kwii-headphones ezilungileyo kakhulu kweli xabiso lemali.
Akukho mfahluko omkhulu kwisandi kunye nentsimbi yokukhansela okanye yokucima. Ngokuqinisekileyo ndithande kangcono nakwi-NC. I-NC ibonakala ibinzela i-bass ngokukhawuleza, inika umxube ogqithiseleyo (ngenxa yongcamango lwam, ubuncinci) bokuhlaziya kunye namandla. Ngaphandle kweNC, i-bass yandila i-little boomy.
Ndiyathandabuza ukuba nabani na oza kuhlambalaza malunga neNqanaba laphezulu leenkcukacha eziphezulu kunye nomoya; Ukugqithisa okuphezulu kubonakala nje kuthulisiwe, kungekho okwaneleyo ukutshintsha i-tonal balance, kodwa kwanele ukuba isandi asikho konke okubanzi kum. Kodwa ngokungafanekiyo ngomsindo wokukhansela i-headphone, i-PSB M4U 2 iyona yodwa into engingayicinga ngayo.
Ngokubanzi, ndiza kuthi le ngenye yeefowuni zeNC ezizwakala bhetele ndizivile - kungekuhle nje nge-M4U2, kodwa ziphantse kakhulu. Ingcono kunokuba i-QC-15? Andizange ndibe ne-QC-15 esandleni sokuthelekisa, kodwa i-Level Over ibonakala ngathi iyandile into engakumbi kunokuba ndikhumbule kwiindwendwe zam zifake i-QC-15.
Ngoku makhe sibone indlela elinga ngayo ........

Amanqanaba angaphezu kweMilinganiselo: Impendulo yeFrununcy
Ukulinganisa iNqanaba elingaphezulu, ndasebenzisa i-GRAS 43AG indlebe / itekisi isimulator, i-analyzer yomsindo we-Clio 10 FW, ikhompyutha ephathekayo eyenza isofthiwe ye-TrueRTA nge-interface yomsindo we-M-Audio MobilePre ye-USB kunye ne-Musical Fidelity V-Can. Ndiyilinganisa imilinganiselo yokuphendula imvama yecala lokubhekisela kwindlebe (ERP), malunga nendawo kwindawo apho intendelezo yakho inqumla ngayo i-axis ye-earal ear when you press the hand against your ear.
Ishati ekhankanywe ngasentla ibonisa indlela impendulo ye-casphone ifanelana ngayo nesantya. Ulandelelwano oluhlaza luyimpendulo ngeNC off, umkhondo ohlaza okwesibhakabhaka unakho kwiNC. I-jury isephandle kwinto eyenza "impendulo" efanelekileyo. Kodwa i-casphone ehambisa impendulo esondeleyo kumgca weplati, mhlawumbi ukunyusa okuncane kwi-bass kunye nokunye ukukhuthaza malunga ne-3 kHz, ngokuqhelekileyo kuyandila kakuhle.
Impendulo yeNqanaba Over iyamangalisa iphothile, idibanise ngokukhawuleza phakathi kwe-400 Hz kunye ne-2 kHz (okanye ukhuthazo oluthile kuyo yonke indawo, kuxhomekeke kwindlela obujonga ngayo). Yintoni ebaluleke ngakumbi kukuba impendulo ayitshintshi ngokukhawuleza kunye neCN. I-PSB kaPawulos Barton indixelela ukuba ngokwenene, kunzima ukuyenza, kwaye inyaniso yokuba ndingayiboni ukuba le milinganiselo ihambelana ngokusondeleyo kubungqina bokuba ulungile-nokuba kukho inzame enkulu yobunjineli emva kweNqanaba elingaphezulu.

Amanqanaba angaphezu kweMilinganiselo: Isolation
Le tstshi ibonisa ukuhlukaniswa (okanye isakhono sokukhansela isakhono) soMgangatho ophezulu (ulandelelwano oluhlaza okwesibhakabhaka) ngokubhekiselele kwi-Bose QC-15 (ulandelelwano oluhlaza). Amanqanaba angaphantsi kwe-75 dB abonisa ukunyanzelwa kwengxolo engaphandle - okt, i-65 dB kwitshathi kuthetha ukunciphisa -10 dB kwizandi ezingaphandle kweso sandi. Umgca wezantsi usetshati, ngcono.
Eyona nto ingcono yokukhumbula, i-Level Over iyona kuphela iphonephone eye ndavavanya ukuba ingqinelana nokunciphisa ingxolo yokukhansela i-QC-15 kwi "jet injini band" phakathi ne-100 ne-200 Hz. Ngokwemilinganiselo endiyenzile kwiindiza, yilapho ininzi ye-droning yeenjini ze-jet ihlala khona, kwaye i-Level Over inomsebenzi omhle wokuwulinda. Kwakhona kunika i-QC-15 ukuqhuba ngemali yayo kwii-frequencies eziphakamileyo kune-1 kHz, nangona i-QC-15 inenzuzo ecacileyo phakathi kwe-200 Hz kunye no-1 kHz, nangaphantsi kwe-100 Hz. Ukukhawuleza ukuphulaphula ingxolo ebomvana ephuma kwisigxina sam vavanyo iqinisekisile ukuba isandi seNqanaba Over sichitha ngaphezu kwesilinganiso. (Kwakhona, andinayo i-QC-15 esandleni sokuthelekisa ngokuzenzekelayo.)
Ukususela kumbono we-ergonomics, iNqanaba elingaphezulu libonakalisa amanqanaba amancinane ukusuka kwi-QC-15, ngokuyininzi ngenxa yokuba ayifaki iiplati kangangokuba i-bulky yokuthutha kunye nokukhulu kakhulu ukuba ifaneleke ngokufanelekileyo kwiingxowa ezininzi zeekhompyutheni.
Kodwa kwimbono yeempawu, iNqanaba Ngaphezu libetha i-QC-15 ngokulula. I-Level Over isebenza (kwaye isandiva kakuhle, nangona) xa ibhetri yayo ehlawulekayo iphela, leyo i-QC-15 ayikho. Kwaye iNqanaba elingaphezu kweBluetooth elingenasiphelo, enoba kungakhathaliseki ukuba abanye abantu bakuxelele ngokwenene uvakale kakuhle, njengoko unokuva kwi- intanethi yokuphulaphulwa kwamakhompyutha .
Ndinqwenela ukuba ndibe nexesha elide lokuchitha kunye neNqanaba elingaphezulu-nokuba bhetele, ukubaleka ukuza kuthatha. Mhlawumbi ngolunye usuku ...
